I'm still battling an occasional no start issue. I haven't put this 94 5.0 truck on the road yet and am still tinkering with things but this no start is puzzling to me. So far I've replaced the fuel pump, Delphi unit, fuel pump relay, rebuilt the tbi and installed the cfm technologies fitting and fuel pressure gauge to monitor that. Also fuel filter twice. Just to make sure. Also replaced tps and set it according to instructions I got on here using my meter. had to elongate the mounting holes to get it correct. Anyways, it all worked fine. Haven't put ten miles on it since November. Around March it wouldn't start. No spark, replaced module, good to go. Then the other day I go up, no start. I was busy and tried it again a couple days later, no start again. Yesterday morning I was going to do the tests on coil and module as per instructions I got on here and it started right up. Anyways I shut it down and it seems like it's sluggish trying to get going again when you try to start it. Cranks fast but doesn't fire right away. I am curious about the fuel pressure sequence. I turn on key, fuel pressure goes up to 10 1/2 or so then drops to zero. I didn't have anyone to crank it to check but what does fuel pressure do when you start to crank? It should go back up, am I correct? Can someone explain the fuel pressure sequence from key on to crank to start? The original problem was the tps sent a signal the motor was flooded and cut fuel pressure. I could give it a shot of starting fluid and it would run just fine. I did wiggle all the wires under the hood prior to trying to start it yesterday so that made me wonder if I have a wire bad somewhere. Right now, this dang truck is so unpredictable that I'm afraid to put it on the road. My son in law got stranded six hours out in Idaho once with this no start, then got it towed and ignition system replaced. He went out hunting the next weekend again and same dang issue! Lol. Anyways if anyone has the fuel pressure sequence I'd be grateful for that info.
