This makes sense to me.. I have no way to jack the car up though. A buddy of mine has a lift though and I should be over at his place next week.

Hold up a minute Ace.,. you've been given some incorrect information.

I have no idea where this guy got his information or maybe he's dyslexic, but the pump is located under a hatch in the trunk. And you don't jack anything up to open the hatch. Unless his suggestion is to fill the tank and jack up the front of the car to look for leaks around the o-ring at the top of the tank. His post is about as clear as mud.

Now..this goober is a buddy.. however he doesn't quite remember that the pump primes the cylinders in high speed mode, not low speed. See your fuel pump runs at two different speeds based on what is going on. At key turn on to start up, it's high speed mode to provide full pressure and prime the engine to start. Once idling, it's in low speed mode which uses a resistor to give it less voltage to run slower. This resistor does go bad and the symptom is the car starts then dies in 2-5 seconds. The way to test/get around the low speed mode is to bend the tab on the relay. When you get into the throttle heavy or wide open, the pcm commands full speed on the pump.
