So my truck wouldn't shut off after coming home from work. It's a 1991 f250 7.3 idi N/A with nearly no blow by.
I deleted the mechanical lift that died with a duralift 40222 and installed a new cdr valve from eBay 6 months ago.
First thing I did when this happened was turn duralift 40222 off and that did nothing. After that I unplugged the two plugs on injector pump and she was still idling at 600rpms. I had to suffocate the motor with shirt with trash bag inside shirt. She was not smoking when idling at 600rpms and after truck sat for 30minutes I checked dipstick which was still full which was where she was in the morning before work (I checked oil regularly since it's so old)
At first I thought cdr failed an was running off own own but after seeing the oil still full makes my friend and I think the injector pump failed to shut an was sucking diesel from the filter?
Thoughts before throwing the parts cannon at her?
