GT40 fuel pumps inoperative

And just in case it matters to the whole troubleshooting process, here is the sequence of events:
- skied one pass and boat died at turn island; restarted, died, restarted died, restarted but died while pulling me out; restarted again and died again; pulled it back to my dock
- at the dock it would start and die, so I figure it is a fuel problem
- put new filter in the FCC, which of course drained the FCC; the FCC was pressured and I had to use the Schrader valve to relieve the pressure before changing the filter
- tried to cycle the pumps to fill the FCC but neither pump would cycle
- shorted the STO to ground per thread instructions and neither pump comes on
- replaced both relays with BorgWarner relays from Oreilly and no change
- have pressed each of the reset buttons numerous times
- starter still turns the engine over but no pressure builds in the FCC

I have downloaded the PCM GT40 manual from the site and it is not the same as my GT40. I am guessing the manual is for a newer model GT40 than mine. My FCC is the spin-on type, at front left with HP pump inside FCC. The manual indicates a 20A circuit breaker located on/near the LP pump. I do not have one of those. And both my ECA and fuel pump relays are identical, unlike what is in the manual. I have so far been unable to locate a manual that is the correct one for my GT40.

thanks for responding, but it did not die when I turned around; it died before the turn island.

Neither fuel pump is running and I don't how to further trouble shoot that.

Poor Man's GT-40 troubleshooting guide

thanks again for replying. I have checked the kill switch, but did not bypass it. Based on the sequence of events it is highly unlikely to be the culprit.

I reviewed the guide you linked to (and thank you) but did not find anything on there except that the relays may be bad. I had already replaced both with no joy.

thank you again for taking the time to reply.

I would fully check out the lanyard switch

PIP sensor is worth checking.

Do you Need the PCM GT-40 manual? You seem quite competent at delving deep and their manual is incredibly detailed   I have a copy on my iPhone. Pm me your email if you want me to send it to you.

Another thread to peruse

Check out this thread Mark,lewey2001 really has a handle on these gt40's. If this does not help maybe he will see this and comment. Can't imagine the wiring diagram is for a newer gt40 than yours,they were pretty much done with them in 2001. Mine is the odd ball with the tubular intake and no FCC which was a 95 only thing

thanks for the responses. I will bypass the kill switch and do some voltage checks.

The manual thing is confusing to me. The engine drawing 2A-2 (p12) is not what I have. I have two identical relays and three circuit breakers in the back of the engine. I have printed the fuel system pinpoint test pages and will wade through that. It may be a while before I get back to this as I have to go out of town for a while. I was hoping to order any needed parts and have them here when I return but it appears it is not going to be that simple.

Thanks for the thread references, but I have read all of those and they were of some help. As far as I can tell there is no place in those threads which tell me where to go if the pumps don't run when I ground the pin on the STO connector.

Thanks again to all of you that are trying to help.

a courtesy reply for the suggestions on the lanyard switch...
I installed a jumper around the switch and nothing changed. Won't be able to get back on it for a few days now.

Check your wire connections in the pump. Didn't someone just find corroded/ broken wires in the pump at the connectors not to long ago.

Well the trouble shooting book says not to be jumping around and at this point I would test at the relays if the main power was present and go from there. It also says that in the event of pump or circuit failure it will throw a code. For that he needs a reader like this one
The relays are the same,one is for the ecm the other is for the pumps

When I first got mine I disconnected the battery,replaced some ends on the cables. Went to launch and no start,everything worked,engine just would not fire. Brought it back home and between Quinner and his tool box and Gun driver on the phone found out I connected all the black wires to ground and all the reds to +. Little did I know that the one black was the + feed to the computer and fuel pumps, go figure I now put a red marker sleeve on that wire so I don't forget between the 6 months of down time.

this section 2A is one of the things I find confusing about the manual. It shows the fuel pump relay and EEC relay being different and in particular shows the FP relay only having four pins. Both my EEC and FP relays are identical and have five pins.

I don't know if my model is newer or older than what is represented in the manual; nor do I know where to get info that is accurate for my 2000 model year.

You guys are trying to help and I want you to know I do appreciate it. I won't be able to get back to the boat for over a week to try anything, so don't think I don't appreciate suggestions just because I cant try them now.

I may go ahead and buy both pumps just so I will have them. They are going to go out someday anyway and I have plans to keep this boat for a long time.
