Hey guys i need some ideas.
I went out to start my truck up since its cold here in michigan.
Started it up about 5 minutes before i left work. went to get back in my truck to leave work and my oil presure was at zero and the ip said oil low or something like that. check engine light was not on.

Shut the truck down and poped the hood to check the oil.
Oil level was good alittle low but nothing to bring zero oil presure.

Had the truck towed back to my house and its dead sitting in front of my house.

I knoticed that it started making a slaping sound, im guesing this is from no oil.

The motor is a 2004 6.0 with 65,000 miles and no warrenty.

Im a poor college student so anything that i can do my self i will.

After a $70.00 tow bill im not a happy camper that my chevy left me stranded.

At first thought, I thaught oil pump because of no oil pressure.
The tow truck driver said these trucks should have some sort of module in them that controls the oil pump.

Im just trying to get ideas on where to start with out going to a dealer.

Thanks for your ideas

how cold was it out when it was knocking?

was it knocking right away or after it was running for a minute?

right now i'm thinking pickup tube o-ring or oil gauge sending unit

i feel ya on the poor college kid front

Oil pump bypass stuck? If the engine was making noise I'd say you have no oil pressure. The oil sending unit is in the back of the block behind the intake...it takes a 22mm socket if I remember right (although there is a special socket for it that I had to use with my radix). I had a sending unit go bad but it pegged my gauge and the scan gauge said I had 121psi of oil pressure WOW. Depending on if you have a place to do it I would drop the pan and check it. You can check the bearings at the same time.

i'd bet that be the problem #1
