Lol your right. There is no oil pressure provision in the ecm.

Just to prove my point two weeks ago a truck came in with no oil reference on the gauge. G80 was broken clean in half...the oil pressure sensor wasn't even connected to the ecm and the truck drove in the shop?

thanks for all the help. ive been talking to alot of people and have been sayin it sounds like the lift pump isnt givin the truck enough fuel for the injection pump to properly work. i was wanting to know what kindve aftermarket fuel pump besides an airdog or fass. im on a limited budget cause im gettin this truck ready to sell. i was lookin into the holly black fuel pump. i was wantin to know your guys suggestions, thanks

 

Just my two cents but if you are about to sell the truck, i wouldnt cut corners to get it running so the next owner has to deal with it. I don't know about the holley black pimp but my buddy just out a raptor on and it was cheaper than fass or airdog.

 

Before my airdog install my lift pump was shot no fuel at all and my truck would run and start not quite sure if lift pump wouldn't let it run unless you have a bad vp44

 

Can anyone help me? '02 5.9 24V. Brand new starter, 1 month old batteries, load test fine, no corrosion. All fuses under hood and in cab check out, no pinched crankshaft wires. Dash lights come on in "on" position, key is turning as normal with some resistance from "on" to "start" (as it should) and still nothing...
What could the problem be? I'm thinking maybe ignition switch or coil? For the likes of me I can't seem to know why it won't turn over....

 

With a multimeter check if you're getting power to the starter. If not it could be the starter relay
