your pick up is computer controlled... it's like "the surveillance state" on steroids. Unfortunately, there are STILL things not monitored by big brother and they always seem to be the things that go bad or if big brother says something is rong...like all government, this thing called PCM won't diagnose what's wrong, it'll only tell you what it doesn't like. That being said...start (no punn intended) by spraying starter fluid into the throttle body n then immediately try n start 'er up...OR..measure the fuel pressure at the fuel rail if you're so inclined.
Check the wires at computer there is a air-condition aluminum hose that messes with wires and melts and causes shorts or could be the crank sensor.
