Well did some datalogging with Auto Enginuity last night. Seems like we are going backwords with this truck. I monitored ICP (desired), ICP, IPR %, ICP voltage, FICM Voltage, and RPM. We replaced the injector and did an injector buzz test and all injectors passed. The truck will no longer start it just cranks, I thought there may be a HPO leak but from the look of the data once the IPR% increases the ICP increases to above the ICP (desired) and stays there until I stop cranking. FICM voltage is also normal. I am having a hard time figuring this one out. For anybody that wouldnt mind taking a look at the spreadsheed from the data please PM me your email and I can attach it in an email.

Update: about 4-5 days ago we got the truck running. Truck runs great now, had a HPO leak replaced a standpipe, and cleaned out the oil rails. This truck had us chasing problems, we finally got all the debris out of the oil system and the injectors changed. No problems
