ok, so when i crank, it fires up great and dies after about 3-4 seconds

so these parts came off a running m42 (drove into garage):

tps, crank/cam sensors, AFM is new from local recycler, fuel pump is confirmed working still as gas does come out of the fuel lines when ign+ is on

what else could be wrong? what could cause the ecu to cut engine after 2-3 seconds?

So the car doesn't idle at all? Be a little more specific to what is going on, it might also be a good idea to check your actual fuel pressure. If you aren't getting good pressure, the car may start up and run for a short bit and then bog and cut off, just a thought.

hmm. it will not idle at all, it fires up, runs for 2-3 seconds, and dies.

i thought AFM, but thats been replaced.

it does have fuel and the regulator was replaced. is there any way the fuel pump could be dead?

it dosnt change with throttle at all, so im pretty sure its not a mechanical falure, it seems like the ecu is dis-alowing the engine to continue running after 2-3 seconds

could it be crank angle sensor? do thoese things die gradually or randomly?

Idle control Valve clean and working correctly?

My bets are on the crank angle sensor.
