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...
