    Question truck wont start after sitting 9 months

    this truck has been sitting for 9 months, former owner was having stalling issues and quit driving it. they said it would die then restart after sitting for a while. we purchased it as is. now it will not start at all.
    we have replaced the pmd, checked the fuel shut off sol, cleaned all grounds, drained and flushed fuel system with new fuel, tied unplugging optical sensor, we are getting no fuel to the injectors when cranking, thinking possibly bad ip. we have checked the glow plugs and have 2 new batterys, have not scanned the codes yet. thanks.

    Sounds like you have covered all the bases. The symptoms sound like classic PMD failure. Since you have replaced the PMD are you sure all the connections are good, especially the ground on top of the IP? Also be sure to check all the fuses under the hood, namely ECM A and ECM B.

    OK ...
    Your LiftPump is pumping fuel right to the input of the FuelInjectionPump. The EngineFuelShuttoff clicks clearly when the ignition is keyed Off, or On.
    The engine cranks , but no fuel sprays/weeps/bubbles from the union where you loosened the line nut atop an injector ... and you gave it a few attempts at cranking , totalling at least 45 seconds.

    -Could be a dead FIP (and it would be DUE , at 144,000Miles). It might be worth inquiring of the previous owner if the FIP is original.
    -It Might be worth replacing the CrankPositionSensor , or removing it and cleaning (wipe off) any metal filings across the magnetized/metallic probes at the tip/end.

    -Scanning codes is a good first step on any electronic-controlled powerplant.

    that sounds like it could be a broken wire in the PMD harness ..........
    I originally bought it
    to put the engine/
    trans in my Bronco

    You say clean gnds, verified how ??? and did you get them all, new PMD, new new; or used but good new, if new where did you get it from, did you replace the resistor in the replaced PMD

    FYI 8th digit of VIN determines S or F
