Did this start only when you changed pumps? If so you either kinked the hose or or the O-ring is not sealing. I doubt it's electrical because a short at the pump will shut the car off electrically.
yea it only started after i installed the pump, drove fine before that. it's possible the o-ring isn't sealing because after I installed the pump i found a little plastic spacer on that i guess fell off of the old pump, i wasn't sure exactly where it went on. so basically if the o-ring doesn't seal correctly then I'll basically be running lean right?
well shit, I just paid $120 for a afpr yesterday thinking that was it.
