it shouldnt be that low... EVER.... especially cold. Mine's about 56psi cold and 42-45 at idle warm...

 

checked the oil when i got home and was full started it up still 19lbs..called my ex boss askin himto bring the efi live over and then it went to 0lbs and i shut it off..he said to check the wires before i do anything and i did break the oil pressure sending unit when i put my intake on..it was kinda brittle since it had been on fire before

 

Sounds like you found the problem. FWIW, I don't think the 99-02 PCMs log oil pressure. I've never been able to log oil pressure in my truck.

 

didnt know that it wouldnt i just assumed it did but oh well i know the problem now

 

well thats a relief

 

yeah, glad you figured it out. sometimes stuff messes up after it's on fire
