To give an update. Sent the ECM out to ACS. Good guys out there got my ECM back quickly. However truck still will only run if vp is hot wired. My insight shows no dtcs. But the key trick still shows p1693. Anyone have any ideas?

All of the computers including the ECM, PCM, Insturment cluster, engine harness and fuse box harness came from the same truck which is whats causing my confustion. i have cleaned and attached then recleaned the grounds several times with the same result. my WTS light doesnt stay on and none of the dash lights flicker at all.

Slightly new here but have looked around, yet still cant find an answer maybe yall could help. I have a 2000 24v that will run when doing the bule chip diesel hot wire to the vp44 test but wont run with the plug. Making me think Ecm. For some background the truck was originally a v10 model converted to diesel. The only part remaining from the gas version is the physical dash and dash harness(insturment cluster was swapped as well). The truck was throwing p1693 code when i had my cheap scanner hooked to it as well as the sending unit code. When i hooked up my nice snap on one it said there was no codes? Anyone have any ideas?
