Fuel pump relay location

try taking off the neg battery terminal for 30 minutes then replace it try wipers.

is the car left or right hand drive .if left hand drive try looking in the right hand side ,also sometimes a fuse will cover more than one item , i would check all fuses

It is located on the firewall on left side to the right side,facing firewall,of the windshield wiper motor. there 2 mounting nuts to remove, then you can swing whole unit down and away from the firewall.

The only part that would come to mind after all of this would be the fuel pump relay. This is located on the fire wall on the drivers side of the car. When that goes bad it does not allow for adequate fuel to cycle through.The other thing would be timing. You need fuel air and spark for the vehicle to fire. After all the test and after replacing the fuel pump relay. I would do a compression and a leak down test. Are you sure that the timing did not jump a gear? You can also look and test the IAC (Idle Air Control) or the MAF (Mass Air Flow Sensor). Also do a test to check fuel pressure. The last Corvette that I worked on personally that had this issue it turned out to be the Fuel Pump Relay. Good luck let me know if you have any further questions.

It is located just to the right (toward the passenger side) of the brake master cylinder/booster.

on the fire wall 1st relay next to brake booster

1st relay on fire wall next to brake booster

There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.

driver's side under the hood above the brake master cylinder ....should be 2 relays there... it's the outer one... they are identical and you can swap them temporarily to check that your fuel pump relay is working.

IT'S NOT ON THE FIREWALL... 1990 Corvette Fuel pump relay is behind the passenger seat, in the small storage box...Take out the plastic shell and it's mounted on the wall ...people answering this had me looking every where...under the dash, firewall etc... If they don't know for sure they shouldn't guess...can upset someone by looking in places it isn't...
