Have you checked the fuel pump relay? Those are very shoddily
constructed IMHO, and could cause a problem like you describe. If you
remove it, pop the cover off and look at it you can see if it has
failed solder joints. If you do decide to touch them up, watch out for
leaving any loose balls of solder in there to cause a short and destroy
the fuel pump driver in your ECU like I did. I still have spare
transistors btw, if anyone needs one.
