1998 Gems P38 dead in the water. I've had some issues recently starting the truck. Seems to not hold pressure overnight and won't turn over the first time. Usually catches on the second. Recently however, it's been very difficult to start. It would vary, but most commonly just stumble and die the first couple times. Initial idle has been strange as well. When it would catch the second or third go, it would idle at 1500 until it warmed up. I didn't like that for a cold engine, so I would shift into drive as soon as I could and just putter along slowly u yup warm. Figured it was the stepper and that I would change it out in the next day or so. I'd say it was also down on power, but how can you really tell in one of these ?
Fuel pump pressure hasn't always been great, but good enough at around 32 PSI and varying with throttle. Now it's zero. I also checked the filter and I have a spare just in case. I disconnected the filter and left the low side open to see if I can get any fuel out of it when I turn the key. Nothing. I carry spare relays and none of them got the fuel pressure to the rail. I'm alone, so I can't listen for the click of the relay, but I can't imagine all five spares are bad.
Am I missing something? It's got to be the fuel pump, right? I have a rebuild kit on board, but I'm going to have to cut the rear seat to get to it as my fuel tank is brimming full. Anyone got any other ideas? Thanks in advance for all your thoughts.
All the best – Dave
