Long story.
Got a new Walbro bout 4 weeks ago with the Whiplash group purchase. Installed the pump by dropping the tank, pump primed, engine ran. No problems at all. Went to school for a week, came home that holiday weekend, and while driving car just shut off.
Check fuses, the relay, all checked out. Pump would not prime or anything. OK, bad pump.
Whiplash sent me a new pump, which I installed today. Only took me an hour and a half, I got mad skillz.
Got it back in, pump primed, car starts and idles.
Drive down my block and maybe 300 ft down the next road, car dies. Adam and I proceed to start to push the car, and while taking a break, he gets the idea to maybe smack the tank.
Hits the tank, pump now primes, we continue on to the JSFBOA meet.
On the way home, after maybe 2 minutes of driving, not even out of the lot, car dies. Try to smack the tank again, some luck. Car would prime, but die after a minute of running. Pump woiuld then not prime.
After a few minutes of me thinking to myself why the **** I bother with this damn car, I go to prime it, and it does it with no bangs to the tank. Test it a bit, and figure what the hell, lets go.
Makes it all the way home, not a single problem.
Cliff notes:
Two brand new walbro pumps, same symptoms. No fuse blown, relay checks out, battery was just taken off charger. Stock fuel pump ran flawless for 75k miles.
Ideas?
