RE: Peterbilt 386 starts and dies immediately
UPDATE:Not sure if anyone cares but I thought I'd give an update. After testing and inspecting I have found the fuel shutoff solenoid is only getting 9v at connector, when measured with good ground voltage is 12v. Removed ECM engine harness connector and insured wiring is under 1 ohm for connector. Seems like ECM has short on ground circuit and is causing voltage drop. Im trying a test ECM and will update accordingly. Thank everyone for your suggestions.
