7.3 diesel stall


Still could be the connector. They are very common to have a poor connection causing erratic signals. With the sensor unplugged the PCM goes into a default strategy for the injection pressure which is why it smooths out.

I'm sure, but the ipr is readily available while the connector has to be ordered. It's coming down to the wire, pun intended.

Ipr first, then if that's not it she's going to the shop. I will let you all know what the outcome is so stay tuned...

7.3 diesel stall


ipr is going to cost just over $300 from Ford. Still haven't purchased it, driving around with icp unplugged so she doesn't stall.

in the meantime, my radiator and degas (radiator overfill) bottle both blew. New upgraded all aluminum radiator plus new degas bottle plus oil change and she's back on the road, better than ever. well, once I get that ipr...

If it is running ok with the icp unplugged the ipr is working fine. It is now just getting default parameter settings from the computer. Pretty sure you will be thowing away $300.

Okay, so? With the icp plugged in the fuel injector pressure steadily drops until truck dies. How I know is bdecuase I have a scan gauge hooked up full time through odbll port.

Why then only and again only if and when either the old icp or the new one with icp plugged in does ipr pressure drop until the point of stalling...??

I picked up the ipr today plus paid for an upgraded and beefier steering gear box made by Redhead and paid for a remanufactured steering column. Truck going in Thursday for all repairs.

I sure hope this ipr is it, only other thing it can be would be a weak high pressure oil pump..?? But she runs fine, tons of power with the upgrades..??

I dunno, but we'll find out.
