When I have gone a day or two w/o driving my 98 GT it has a hard time starting. The car turns over just fine and I can hear the engine rev but then it will just die. Starting it while pumping the gas a couple of times gets it going. After it starts it drives fine. After conversing with some local gear heads I was thinking it sounded like the Throttle Position Sensor. Thoughts or advice?

 

got a optima battery? they will do that

 

The TPS is where I would start as long as the car idles fine after its running. If it has trouble idling too then I would pull Idle Air Control valve and clean/replace that.
