GT40 No Start

If you look at the picture it’s way harder to twist than whatever you showed us all twisted up

When I bought my SS, I had a dealer replace the HPP and hose before I brought it home. I had to replace the LPP about a month into ownership. The hose is much heavier than the one yo showed us all. That thing looks horrible.

I was planning on asking your opinions on fuel hose to replace that. I have bought fuel hose before for random stuff from ACE, they have a good selection of hose. But when I bought marine grade for the fuel line on the 83 I went to a boat supplier and it was not cheap, but that stuff is way beefy compared to that little hose. It looks to me like ordinary automotive fuel hose.

I’d go and get PCM’s kit anyway, it’s a heavier hose and clamps to match. Used to be a dollar didn’t see how they could do it for that, it’s now 12

At least you can ski at sunrise to sunset and then some—and weekdays are
Golden if you’re an early riser!

Wishing the best.

I’ve burned about 250 gallons of gas on Deep Lake so far this season. The chain has been a nightmare the last few years with rain and flooding. Good thing you’re on high ground, Gary! Maybe Quinner will throw a party and I’ll see you again soon!

Good one. It is probably pretty high up by you guys too, but much more swim-able no doubt.

Unfortunately we are no-wake everywhere around here because of the recent storms, I was lucky enough to have my mom come and hang with the kids today so I could get out there and install the new interior and do major detailing. I was not dreaming last night, I was up all night until the wee hours cleaning up the mess made by 8 weeks in two different shops. Which leads me to the explanation of the problem. Here is my conclusion and process last night which led me to it. I will attempt to present it somewhat completely but it was quite an ordeal as you know.

Started by checking voltage from lead all the way to the HP pump itself along the way refreshing connections as nicely as possible. 12 volts to the HP pump without a doubt. So why is it not moving fuel? Inspect that little hose, it is in tact but somewhat soft from sitting in fuel, notice that it has a little crease from where it might have been folded/twisted, simulate what might happen if the filter binds in the can when it is being screwed on and sure enough that thing folds like it was stuck that way for about 8 weeks.


So I flipped it, (this was about midnight so I'm not going to ACE to buy fuel line) thinking it will not likely kink spinning in the opposite direction. I also trimmed a bit off the end to have a nice tight fit and be sure it didn't bottom out in the can and push up to kink also. Screwed on the can so carefully that I was sure the filter didn't bind. Now I have positive without a doubt voltage to pump and no way that hose is the problem. Why is the fuel not dumping out the return in the tank?!

I decide that I need to go back to square 1, lots has happened in two months and who knows, better start at the beginning. Check the screen in the fuel pickup in the tank. That is where I notice the most disturbing thing, there is no anti-siphon on the pickup! Look at the return and there it is, someone (not me) took them both apart and reassembled with that on the return, no way for fuel to flow into the tank. I am so excited I am sure that I have figured it out, make them correct, turn the key to hot and the fuel is dumping out the return. Yes I have done it, time to celebrate, turn to start and nothing. Are you kidding me!! Maybe if they had that wrong what else did they do? Look carefully at the fuel lines routing from the FCC to the injectors, try to remember what I read, it goes passed the regulator and then to the Schroeder valve? or the other way? I'm delirious because it must be 1 am but I'm going to flip those to see, what is the worst that could happen? Hit the starter and it starts and runs like new. Run into the house to tell my wife, get reprimanded for smelling like gas and sent back outside, go back outside shaking with excitement from the accomplishment. Wow.

So after that I spent some time winding down and preparing to put in the new interior cleaning up the mess and whatnot.

Sidenote, that was Friday the 13th and there was a full moon so I walked down to the lake to sit on the dock and enjoy. I noticed the neighbor's jetski was not on the lift, and I am the guy he usually asks to pull it and I haven't yet. So I go grab my light and find it floating down the way, take a walk down the shoreline to secure it then, finally, take in the view, what a night!

Lessons learned. When you are stumped, take the time to restart from the beginning, do not assume anything.

I admit that it is likely when I installed the new HP pump at the very beginning that I could have twisted that tube and that is all it was all along. Do I regret going through all this? Heck no. I needed to pull the boat to do the interior and this was the golden opportunity, that is why I threw in the towel so willingly and passed it off at the start, the timing was perfect. Also, when we bought it I wanted it to like new for next year, engine gone through thoroughly, many shakedown cruises and no bugs, and for the interior to get done. I can now say that goal has been met for sure. I have always loved looking at this site, but mostly soaking up info without much opportunity to use it, but after the support I got from everyone here to figure this out I feel a deep and sincere appreciation for the Correct Craft Family and have never been prouder to be a par of it. Thanks to all of you.

Waiting with bated breath, for the answer to the problem.

There had been a change over the years because the older style could leak. I’m sure skidim has the picture of latest version

It should be 39 +/- 3 psi.

You probably have a fuel injected car hanging around that you could test the gauge on to see if it's accurate if you know what the car system has for a pressure spec.

Or you could get a loaner gauge from a parts store and compare readings.

It's simple to hook up, they don't cost much and can keep you from throwing money and parts at it.

It seems to me that you still haven't put a fuel pressure gauge on it recently.

Without knowing the fuel pressure with the key on engine off and jumpering the pumps with the STO plug, you really don't know much at all

What's the pressure with the newest HP fuel pump installed

You could randomly throw a distributor in it as the easiest way to resolve a PIP issue if there is one, since the distributor has to come apart completely to change the PIP sensor

Or you could randomly throw a TFI 4 module at it too, but they're all shots in the dark.

So............I'll yell it kinda loud      WHAT'S YOUR FUEL PRESSURE?
