    Not much luck yet with wiggling wires opening up the harness. Cleaned several ground connectors. Any more ideas?

    If I take the battery cables off for awhile, will that give the ecm a reboot???

    Is it possible that if the high pressure oil pump. The o rings failed or the pump. Itself , the ecm doesn’t want to connect to the ipr valve. Because I have no voltage to the ipr

    Check the 5 amp fuse in the fuse box for the ignition supply to the ecm. Pull it out and check the pins for any corrosion. At key on, you should have power here. From here it goes to a 12 pin connector near the intake at the engine. Key power goes to pin 9 of this connector. Look for wire K78M, 16 gauge violet in colour. Check for key on power here.

    Little screw up: I had the ignition key in the on position...pulled a few relays.... and now no power in the ignition and dashboard is dead. (Not smart). Any ideas on that one?

    Pulling those with the key on really won't hurt anything. If the dash is now dead, I think you just put one or more back in the wrong spot. It is easy to put them back just one tiny row off. One nice thing is there are no extra terminals in the sockets themselves, so pull the relays one by one and really make sure you put them back in and the pins of the relays go into terminals in the sockets.

    All relays are kind of bypassed, there is power at the ipr valve. Oil sensor below the ipr. And Idm has power to. Still not building up oil pressure. Rpm at 150 while cranking. And the oil pressure gauge is stuck on 40 psi. Didn’t moved yet
