If car sits for more than a few hours, the car will not start if immediately attempted. If you jump right in and turn the key all the way to start, the electronics will freak out, the engine will turn over but not start. The vehicle will stutter a bit. The electronic tachometer goes all the way to redline and then returns to zero. If you wait a second and start again, it starts and runs fine.
If you get in the car, turn key to on and wait a few seconds, the car starts fine. It only goes crazy if you start immediately after the car has been sitting for hours.
Cannot find any information online that mimic this problem. My thoughts are it must lose fuel pressure as it sits so it takes a second to re-prime the pump and reestablish pressure? But there are two fuel pumps, no fuel pump relay, no fuel filter as far as I can tell. Is it bad pump? Bad FPCM? Bad injector allowing fuel to leak into a cylinder?
