the problem i am encountering is with my 1995 isuzu fuel pump (i believe) the problem started when i tried to start my truck with no luck... the engine turned over adn there was a spark so i narrowed it down to fuel. i replaced the fuel pump after checking all fuzes and replacing the fuel filter. The truck started right up. The next day i filled up with gas and the truck would not start again. I then took the truck the home and drained the fuel tank. took the pump out and checked everything. i hooked up my multimeter and everything checked out. hooke it back up and the truck ran great, however when i filled up again i had the same problem the truck would not run...! any suggestions would be great!
