ok i have a 2019 silverado with the 6.0 engine i bought it at a auction with no key had a key made but couldnt get it programmed fooling with it i did the 30 min. relearn the truck started and ran fine but the service theft light was still on so i got in the truck to drive it and check it out and when i drove it around the block the oil pressure dropped i was not but 4 mins . from my house so i kept driving it and when i got home the engine died and would not start back it will turn over i looked under the hood oil was everywhere the oil cooler line had came off the little clip that holds it in was gone i filled it backup with oil and it would not start so i had the key man come out and program the key so the theft light is off so i thought it was because of the theft light it had some reason why it would not start but its off and still the truck just wont start i cant figure out what happen i thought i had done ruined the engine running it with out oil pressure but it did not lock up or make any knocking noise when i drove it back home it just cut off and wont start any ideals what is causeing the truck not to start it has no codes?

 

aint got no gas in it

 

yea i put some gas in it tryed to check fuel pressure but no where on fuel rail is there a fitting hooked up my scanner and it does not read fuel pressure either fuel pump is running

 

If you have compression and spark which I'm sure you checked before posting this, then spray a little bit of starting fluid in the air intake and see if it tries to fire.
