Starts and immediately stops
My dad calls me this morning saying that his 2000 GMC will start and immediately stop. He tried it multiple times with the same results.
I know on older cars with points, there is a bypass in the starter to pass current to the ballast resistor to give the coil full voltage during cranking. Sometimes that would cause problems exactly like this. But there can't be anything like that on these new trucks, right?
Anyone have any ideas?

does his security light stay lit or flash like its supposed to? If so, it could be that the ecu or bcm (dont remember which) isnt sensing the resistance that its supposed to from the ignition (key hole thingy). If that were the case it would most likely mean a bad key hole thingy (ignition module?).

Didn't mention anything about revving up. I'll ask some more questions when he gets off work. VATS sounds like a real possibility. I thought they ran about 15 seconds before dying with the VATS.

Mine does that every once and awhile , sometimes at a stop sign to . But I can keep it running if I push the throttle down a little more than before & use the brake to keep the rpm's up at stop signs . Dont know what the deal is .

If it immediately dies out no more than one second after it turns over, it's very likely to be VATS related. Bad switch may be cause, or it just may need to be relearned.
