Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam.Your car has a failing fuel pump. The pump is a small electric motor inside the fuel tank. As it starts to fail, it might stop and get stuck or the position it hits between contacts. By hitting the tank, he jogged the pump which moved it slightly and allowed to to run.The repair is a new fuel pump and fuel filter assembly. Driving it and hoping that smacking the tank each time will allow it to run will leave you stranded somewhere.
The fuel pumps are a very common issue on this and many cars so its just a matter of the odds. 8/10 you can likely hit the tank and make it run so.
