Greetings: I really appreciate your website. Thank you for making your knowledge available to the rest of us. Here's the whole story on my G20 Beauville Van. I parked it one night after doing some minor electrical work (installed some driving lights). Next morning, she would not start. Long story short, I've got what appears to be decent fuel pressure at the base of the throttle body. If I jump the FP Relay, and crack both fittings just enough, I seem to get a really strong spray.
I've gone through all the fuses and breakers. I am confident they are fine. All have proper continuity. I get a good reading from the Crank fuse as well when turning the engine. On a couple of occasions, the van did start (after I replaced all the fuses but noner were blown...?), but would sputter horribly as the FP Relay would flutter. Eventually, the relay would not stay engaged and she would stall, not to start again. That's what lead me to believe the PCM may be bad. I thought that by pulling all the fuses, and power was cut from the PCM and other components for enough time to "reset"--if that is possible. Cannot duplicate this process again however.
I have replaced the FP Relay jsut for grins and giggles, but that wasn't the problem either.
The van will start if I pour fuel directly into the TB. Obviously, she would not run past burning whatever fuel I pour down her throat.
I have replaced the PCM under the drivers seat to no avail. Also, using a long screwdriver to my ear, I cannot hear the injectors triggering.
I don't think it's the oil Pressure Sensor as the FP Relay should first activate regardless, as I understand it. I am convinced the problem is electrical.
I understand it may be possible that the fuel pump is the problem as it may not be creating ENOUGH pressure, even tho it sprays a healthy stream when I crack open the fittings (when jumped as stated above).
The only thing I can think of is maybe a fuseable link some where, but I thought the only ones were to the starter, and those seem fine. I hope you can tell me what else to look for. I can't afford to take it to a shop, and I'm a pretty fair shadetree mechanic. Maybe I pulled something loose under the dash while wiring the driving lights, but I fail to see what that might be. It's really a great van even after all these years. She has some rust, but the inside is nice and clean and I really need to get her going. I look forward to your response.
Many thanks,
Chris Baker
