Me and my buddy just put a new icp sensor in my 2004 f250 psd. Turns out the pigtail is really messed up too, so just left it unplugged for now. Went to start the truck and it does nothing. All the dash lights come on, but when the key is turned it doesn't do anything. Any ideas?
Ae you saying now that it won't crank over? Check fuses, batteries, and cables. If it is cranking over, is the idiot oil guage showing oil pressure? Maybe the pigtail is shorting out and giving the pcm no info, even unplugged.
