Hi guys, hope you can help me out here! Boat is '97 SS. Just recently had a fuel pump issue. Turned out to be the relay of the computer. Boat ran perfect, even better then before, which was already good. Happy me! Only a week or so, and a couple hours of use later: same issue it seemed (no priming of the fuel pump. Engine turns over but doesn't start). Not so happy me. Figured maybe the relay for the pump went out this time. Changed that out, but no. A friend told me to bypass the relay and connect fuel pump directly with battery to see if fuel pump worked. Tried that, but killed the whole engine. Somehow, I must have caused a short circuit. (Yes I'm an idiot, and I know it, that's why I usually don't try stuff like this myself). Engine didn't turn over anymore; nada. I checked the fuse between the battery and the engine, it's fine. Changed relays again; nothing. Really unhappy me. Had a mechanic look at it today. 3 Fuses (? 60, 15, 12.5) on front of engine were checked and are OK) He found out that the signal from the ignition doesn't reach the pump. He put a wire straight from battery to relay (computer's relay, if I'm correct) to the green/pink wire, so the pump engages as soon as you put ignition on. It now starts giving extra gas, but runs really rough. Doesn't idle. Mechanic says it's the spark plugs, but since it ran phenomenal only a week ago I don't think so. They might not be perfect (had fuel on them) but that's mainly of the rough running today, I think. Or they must have gone bad overnight. My guess is that wiring the pump straight to battery 'confuses' the computer, and that that's why it's not running well. Maybe not, or even probably not since I'm an idiot... but either way I don't think the main issue are the plugs. Any ideas and suggestions?! What might have gone bad when I tried hooking up the pump to the battery? What else to check or try? Thanks all! ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

That is the test connector where the code reader plugs into. It is plugged / housed into that cover,marked ECC TEST,that is just to the left of the red colored alligator clip. What you are doing is providing the ground to the pumps,which is what the computer normally does when you go to start. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

No improvement whatsoever yet. Jumped the pump as in the photo. Same thing: no idling, running rough, lots of smoke from the exhaust. Changed spark plugs, just to be sure, but still the same. Any other suggestions? ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Hmmm, removed jump wire and it started again. But ran same as the time it all went bad: surging at idle. As soon as you put it in gear it stalls. Managed to start a few times like this . Sometimes didn't start, then had to use wires to jump it again, with some extra throttle. Starts and runs super bad/rich, then as soon as I remove wires runs great, then stalls when I put it into gear.  Edit: pump still doesn't prime, but starts anyway, sometimes. ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

No the reader won't test those. Keep in mind the testing of components will not differ from that of automotive ones. Google how to test them, some Mustang sites are really good. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

did you verify that the LP pump was indeed pumping fuel when you used the test jumper to ground? it's possible the LP pump is shot or the screen (internal filter) inside it is all gunked up. I had a very similar problem and the old LP pump worked intermittently. new pump fixed it. autopsy on the old pump showed the screen was all skuzzed up. ------------- As far as I can tell, I'm not quite sure... |

| Just my $.02, but I think the guys here could walk you through some troubleshooting if you provided a little more information and feedback on your tests. It's still not clear whether your fuel pumps are running with turning the key or using the STO and verifying what the fuel pressure is at the rail and whether its holding pressure (to start or running (rough)). I would spend a little more time trouble shooting before I flew someone down and spent that kind of money. |

One thing to remember with all this testing. Electric Fuel Pumps are lubricated by the fuel flowing through them. If you dry start an electric fuel pump you can do damage in as little as 10 seconds run time. Saying you have a new pump in there might mean nothing if it was dry started due to some supply issue. Sorry to pass this on but those are the facts with an electric fuel pump. What do you see for pressure in the system as you try and start? If it is not at full pressure they don't start or if they do they run poorly. ------------- |

Even if it is the ECM it's not the death of it. I had mine running on a 4cylinder Ford ECM with a Moats chip. I think some have had success having their ECM's repaired too, PlanetNautique has the guy's who are up on that.

Oh my god, bummer of the century (well for me it is..) ;same problem again!  Checked/cleaned those connectors again. Spoke with my buddy who got it going last wednesday, he suspected the thick red wire right next to them had something to do with it so I cleaned and wiggled there, but nothing. Boat problems always suck, but this intermittent stuff is the worst!

[QUOTE=TRIP] The culprit The green wire from memory goes back to the dash for the engine alarm cct (SLOW) and the grey is the tach signal to dash. Not sure where that larger 12V red cable is going to though. It may just be the main power wire to dash via dash harness plug. The v drive wiring configuration in your Super Sport is a bit different to the direct drive. Being a 97 SS I assume it has the FCC I think I can see it just below LP fuel pump. Can you get a wider shot of that picture to confirm. Another thing to check is for a extra large fuse in the battery box that is actually the power source for the ECM. PCM did a retrofit that eliminates this extra fuse and wiring. They were a known cause of intermittent problems.  ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

Sander, do you have a battery switch? If so, remove the cover and make sure the internals are still intact, connections good. Then, as I'm sure you have tried, look closely at that red wire, where it comes from and where it goes, look for bare wire shorting. See if there are any splices or crimp on connectors in the area. When you cleaned those contacts and it seemed to be fixed, you may have just moved something else enough to cause it to connect for a while. You wiggled the red wire, try wiggling everything in the area that might have moved with your wire cleaning to see if you can find the bad connection. ------------- '63 American Skier - '98 Sport Nautique |

Reporting back again...   So as you can see the ground-pin got loose. Everything got corroded. Seems like the boat has been used in salt (was told it wasn't). Anyway, got the ecm to a guy who's going to try to fix it. If that doesn't work (and if it does, to have a backup for when it goes wrong again), where do I find a replacement? Don't think you can just replace the 60-pin connector, or can you? As for a new ecm, I think they're not available anymore (?), but I saw some threads on PN about replacements or so, or ways to fix them, not sure.... Gonna try to find those threads, but meanwhile any advice is appreciated! And again thanks for your help y'all!

I think the hardest thing will be to find a C1A1 fast. One of the PN guys burned my Moats chip,I had it shipped directly to him so that I was not paying shipping back and forth.

Mark,I had them burn the 290 tune into my chip. At the time the 300 was not being cooperative in its download and didn't seem like it was going to happen any time soon. I thought about getting another chip and having it burned but I feel funny about bothering him,after all he would not take anything for his effort. I did send off a gift card and some giant cable ties to close the ECM back up though. PS Mark I thought the 300 tune addressed a rolling idle issue that some had. I don't know if anything else was changed. Knock on wood mine seems to idle fine so I wasn't as concerned. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Gary the C1A1 variant of the Ford EEC1V must use the same output pins on the 60 pin ECM connector as the PCM GT40. There are many variants of the EEC1V even in Australia. I went to a local wrecking yard and cut the car loom plug and removed the 60 pin connector from a junk ECM to make up an extension cable to relocate the ECM in my Sport to far less "hostile" area under the dash. Trip (Jander??) the pins are easy to replace in the connector just pry out the red insert and the pins are then released. Ford Australia used the EEC1v computer on the 6cyl Falcon for quite a few years and these were very popular cars downunder. The pinout on this ECM was very different to the pinout on the Gt40. I may have a play with this setup and source one of the C1A1 units from US along with the Moates chip and programmer/reader and see what is possible. Would be nice if you could then enhance the tune for other performance upgrades like my Megasquirt ECM.

I would just like to add that the original guy who figured this out had said you could also use a Ford Mustang ECM marked D1L1 in addition to the C1A1.

Aaaaannnnddd the story continues... That took longer than expected, to get the ecm back (kind of to be expected here in Costa Rica; most everything goes slowww...). But on Friday I put the ecm back in and it worked! Went wakeboarding yesterday, rode a couple sets with some friends; all good! All pleased, idling back to the dock... boat dead...   NO WAY! This can't be happening.... Exact some issue AGAIN. The pin of the connector is still firmly in place. Checked the relays, nothing there. This is driving me mad, got it to work 3 times, every single time it works fine for only one day. Haven't been able to buy another ecm and the chip yet, but I'll be working on that today. Fingers crossed that solves it... ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Sander looks like the ECM may have seen too many heat cycles. Once it gets too warm now it becomes unstable. You can prove this by letting it cool for 30 mins or so. Lift the engine cover and wait 30 mins. Then try to restart. After a bit more research it appears the ECM they found compatible is from a 2.3 litre 4 cyl Mustang. These ECM's used the same batch fire method for the injectors as PCM did with the GT40. ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

Here is what I understand Paul from a question on the eectuning.org site Question- "I believe the part number to be F4FF-12A650-LB. The PCM service manual listed the ecm as -12A650- and I checked the ecm last night and could only find a non-ford looking sticker with the other numbers." Answer- "12A650 is the ford designation for ecu, as in pretty much any ecu. F4FF narrows it down to year and vehicle model to some extent. LB is the specific part, for both hardware/software in this case. The number that will help us help you is the hardware code from the label. Hence the request for pics. Any other EEC with the same hardware code can be chipped with software from your part." "EFI-MA39C is the hardware code,E290 or 300 is the catchcode which encompasses software and hardware by association". The ECM's marked with C1A1 or D1L1 are the ones to use which Rock Auto is not telling you. https://eectuning.org/forums/viewtopic.php?f=2&t=22155" rel="nofollow - Here is the original thread on eec.org,they are the guy's who helped the OP figure this out.

Update, again: had the ecm checked by a lab where they confirmed it went bad. Luckily in the mean time had ordered an ecm off Ebay and bought the chip that I had shipped to Tom from PN who put the software on it and sent it off to CR.

Which tune is Tom doing for you,the 290 or the 300? I had him do the 290 for me since the 300 hadn't been cracked yet.

I'm not even sure, never discussed that. Assuming the 300 though since that's the updated version, right? So no reason to use the 290 then. I'll check with him though and will let you know if it does turn out to be the 290. ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

| I went through this whole forum and found that some of the issues fixed it for a couple of days and then I was back to square one. I found my problem. Please see my video for details:https://youtu.be/9Cg3aFHsPZU |

Justin, this is a very cool discovery. I would have never stumbled upon this as an issue. Congrats on the solution. I would be very curious to know if this was a widespread manufacturing issue with the ECU. ------------- Bud 1999 Sport Nautique |

That's awesome! Congrats on the fix. That's an obscure one. Nice sounding exhaust too.
