89 GL, intermittently shuts off, with no predictability and won't restart. I Figured out that if I tapped the fuel pump it would start up again and go fine (On a six hour trip, it would stop about every 2 hours) The pump was getting power, so I put in a new pump, and presto, no problems for about a month, then all of the sudden it started happening again, three times this week already. And still if I tap the pump mount, it starts right back up and will run fine for a couple days. During all of this time the car has been doing this thing when I fill up at the gas station, I get back in the car and start it up and it immediately dies after starting, I figure it is connected somehow. Gas seems clean, (no rust or anything visible from filter) and the wiring looks and tests good to the pump. I am at a loss right now. Can anyone help me put the puzzle together???
