[QUOTE="machoheadgames, post: 435551, member: 18789"] that is unlike any PCM issue I have ever seen anyone experience, the number one failure is the capacitors die and then it won't start (cranks, but does not run), unless you wait for the check engine light to turn on and the PCM to fire up the ASD and fuel pump relays. the other semi common failure is the alternator voltage regulator goes bad. HOWEVER, it is an electronic device and can potentially fail in many different ways. I would remove the PCM, take the lid off of it (just a few screws IIRC) and look at the circus board. See if anything looks like it exploded in there. I would think if anything went bad, it should be fairly obvious since you heard a pop loud enough to be audible while on the highway. I bet you'll find the issue in the PCM based on the symptoms. [/QUOTE]
