97 No Start, Another Ugly One
Looking for any insight you all can give me. New guy here. Hi!
74,000 mile truck. One of the rare occasions where I was actually in a vehicle when it died. It was damp, pissing rain actually, and I fired the truck up. It ran for about 20 seconds. I gave it a slight throttle, maybe 1400 rpms and it died and has never started again.
Didn't want to jump to conclusions so we began troubleshooting. WTS light is working. Fuses/relays are good. No codes, well I lie there was an IAT code but I saw the connector fell off. Put it back and no codes. Using a Snap-On Solus. Checked GPR and it was good. Ohmed out harness and it was good on one bank and moved on. I didn't really think it was an issue due to the way it died so I skipped. I know, I know Im just being honest. Oil resevour full and stays full. Tach moving.
Scan while cranking indicates an ICP that slowly climbs to a max of 124 kPa. If my math is right thats like 17 psi. That aint gonna work. Fuel pressure was building up at the schrader to around 20 psi but that may be another issue. It was less than 1 ms when cranking. .42 ms to be exact. I think it should be between 1 and 6? Pulled the ICP connector and it jumped to 16600 kPa, still no start. IPR was loose when I tapped on it I could turn the jam nut a good turn. Tightened and no change in any reading or behavior. No smoke out of tail pipe when cranking. Injector buzz test sounded good with number 7 being slightly louder than the rest. I pretty much ruled out the IDM (which I was sure it was due to the moisture) Passed on the scanner but you know how that goes. I hate throwing parts at it but I don't have the proper tools to deadhead the HPOP and check. Having said that, I am leaning on trying to fab up a test kit or just ordering a IPR and having at it. Any thoughts?
