Also, when cranking, does tach needle bounce? If not check to make sure cps is plugged in and?or swap out cps with known good.
yes my oil pressure gauge does rise when cranking. oil level is fine in both areas. i also replace the cps sensor thinking it was the problem and nothing

replace with a new oem cps it was only $20







they told me it could be the idm but dont want to waste $200 on a rebuilt unit. will the 1997 7.3 idm and pcm work on a 2001 7.3
