[QUOTE="P49Y-CY, post: 16352450, member: 10216"] got some info on what this was (and still is) lol. to answer my original question, it is def a fuel issue. the car was driving for a while, but for the past month or so it won't even start anymore. so i bought the wiring manual, and started to take the car apart so that i could check out every wiring harness on the car, if need be. and i did check, and all the wiring is good. there is continuity on every single wire related to fuel delivery in the car. when i jumper the fpdm connector to bypass the pcm, the car starts right up and idles. so, since it is getting good power, and i have swapped out the fpdm from my other car (known good), my conclusion is that the pcm is not sending its duty-cycle signal to drive the pumps, and i need to figure out how i am going to change out this pcm. that is one part i don't think i can swap out myself because of all the pats and gem module software changes needed. this is by far the longest my car has been down since i bought it. but it definitely has been a learning experience [/QUOTE]
