Ran fine change oil soon light came on. Just changed oil 400 miles ago check oil light came on and 2 seconds later engine stalled pulled over to the side of the road checked oil full. Turned over and started for a second and died. Then rolled over no attempt to start. Replaced pcm with remanufactured had it flashed at auto parts store and installed by buick. Dealer did not have correct scanner. They had #2 not # 1

Hello,

Ok, so why did you replace the PCM?

Ok, as far as the Oil Light coming on and the vehicle dying soon after, in most vehicles when the Oil Pressure get to low it will shut down the vehicle it's a safety feature so you don't blow up your engine.

Now with the No Spark it could just be a bad Coil. Or a Bad Cap and/or Rotor.
