75 fuel injected 1.8. It's happened twice now. Pull into the gas station, fill up, then the car won't start. It will turn over but not catch. Both times, I waited a half hour and then it fired right up. Any common things I can check?

Most common problem is the fuel pump ... not the fuel pump itself, but the check valve in it. D-Jet, L-Jet, CIS system are designed to hold 20 or so lbs of fuel pressure in the system for 10 - 20 minutes so the fuel does not boil in the pump. Pump doesn't like pumping vapor.
Hook a fuel pressure gauge into the system and see what happens to the fuel pressure on hot shutdown. If the pressure bleeds off rapidly, it's the check valve that has failed. |
