i just got an oil change and the computer reads that my oil pressure is at 0psi
wut could be the problem?

check youre oil filter if it on ok check youre oil level check for noise (maybe the wire for the sending unit is bad ) engine noise or lifter

If the filter wasn't on, oil would be all over the place! I'm gonna ask a stupid question, but it has to be asked. You were doing an oil change, did you put oil in? Sorry, I hate to ask those things.

It isn't an issue with the oil pressure sending unit (or it'* wiring) because when they go out, or there is a short in the wiring, it'll read maximum pressure due to the infinite resistance in the circuit. As such, he'd be seing something like 99psi.

From a mechanical aspect, if you're not getting oil pressure, that'* indicative of pump failure, which by now, if that were the case, you'd also have catastrophic engine failure.

But if you pop off the oil fill cap, peer in with a flashlight, and see if there is fresh oil in there, that means the pump is infact ok, and that oil is getting to the upper portions of the engine.

In which case, it would be indicative of an electronics gremlin

i do indeed have engine failure
my car wont start and before that it putted all over the place and the rpm'* wouldnt go past 3 and occasionally it would shut off while i was driving

Warranty? If its a GXP, you must.

Never mind, I just read in another thread you have a 96 Aurora, didnt you get a DIC warning for low oil pressure. It chimes at 4-5 PSI.

If it says zero, then, yes, its time for a new 4.0 or send the car away for parts. As mentioned in another thread....

That would be indicative of the motor or something in it seizing due to lack of lubrication and cooling (oil acts as a cooling mechanism too).
