Anyways, opened up the IDM and everything was dry & visually looked vine. Nothing blown that I could see.
Tomorrow I'm going to ohm out the injectors & check all the harnesses. Today was more mechanical, tomorrow will be a wiring nightmare. Hope to have some suggestions soon
I'm not sure, just bought the truck this past Tuesday. She has around 240xxx miles. Oil level is normal tho & it's not completely black or smell of anything.
So here's the deal, I bought the truck, ran great at the guys house, great about 10 miles down the highway on the way back. Got a Engine Temp light & pulled off. The radiator drain plug was wide open. All of the coolant gone. Tightened it up, filled her up, and let her cool off a bit. Fired it up and pulled up to a pump out of the rain for further inspection. Didn't seem to be leaking so I got in to start it, ran about 15 seconds and then shut off as if I turned off the ignition. Tried again, ran about 5 seconds and shut off... Then just cranked and cranked. Installed a new battery (one was 4 years old, other was 6. And yes I know I'm supposed to replace them in pairs, but I was 45 mins from the house with only $120 lol) but anyways, didn't change anything but the crank speed. Also replaced the CPS at that time, no change. Sputtered here and there. Towed her home, replaced the other battery. Ran for about 30 seconds and shut off... Unplugged the ICP and she ran fine for almost a full 20 mins. Shut her off, tried the next day, ran for about 2 minutes & went back to only cranking????? im so confused
What's the fuel pressure when cranking? What are your ICP and IPR Duty Cycle when cranking? Here are the pinpoint tests for P1293 and P1294 if you want to do them:
AB20 DIAGNOSTIC TROUBLE CODES (DTCs) 1293 AND 1294: CHECK FOR VOLTAGE ON HIGH SIDE CIRCUIT
DTCs 1293 and 1294 indicate an open circuit exists on the high side circuit between the IDM and the injectors. The following table lists the circuits to inspect while performing these pinpoint tests, based on the DTC retrieved during the KOEO On-Demand and Injector Electrical Self Tests.
DTC_________High Side________Injector Bank
1293_________1087 (O)_________Right
1294_________878 (PK/Y)_______Left
Key off. Disconnect both connectors on the bank with the code. Key on, engine off. Measure voltage on the suspect high side circuit Pin C on the injector vehicle harness connectors to battery ground. Is battery voltage present?
Yes: GO to «AB21».
No: GO to «AB24».
AB21 CHECK INJECTOR RESISTANCE
Key off. Suspect injector valve cover connectors disconnected. Install Rotunda Glow Plug Injector Adapter 014-00935 or equivalent. Measure resistance between high side and low side injector terminals on the adapter tool. Is resistance less than 5 ohms?
Yes: Fault may be intermittent. GO to «AB15» (back above).
No: GO to «AB22».
AB22 CHECK HARNESS FOR OPEN
Remove valve cover. Disconnect injector harness connector. Measure resistance between injector connector and exterior gasket connector. Is resistance less than 5 ohms?
Yes: REPLACE injector. RERUN Scan Tool Diagnostic Test.
No: GO to «AB23».
AB23 DETERMINE WHETHER GASKET OR UVC HARNESS HAS FAILED
Disconnect UVC harness from gasket. Measure resistance across each contact in the gasket. Is each resistance reading less than 5 ohms?
Thanks I aprriciate it. The ICP was unplugged so it was at 2450 psi or so. The IPR was at 15% at idle. I'm just going to tow it to a show instead of throwing parts at it. I need to have it finsished and drivable because I'm boring a vehicle right now lol thanks for the replys
