SOURCE: trying to locate fuel pump relay for 1991 corvette- coupe

The fuel pump relay in the 1991 corvette is located under the IP on the pass side.
Open pass door, unscrew two screws under the glovebox (you will be upside down in the car), take off the fuse panel, unscrew third screw to plastic plate underneath glovebox, pull away carpet (velcro), pull down plastic plate (watch out for the wiring to the lamp), then under the glovebox you will find a number of fuses and relays if you dive in under there DEEP, prob 4 or 5 in a row, not really sure wich one, but one in the middle is the fuel relay, and they are the same (interchangable).
Take a look at --the12volt.com/relays/relays.asp--
It´s those relays we are talking about.

Have a1995chevy corvette fuel pump does not work fuse not blown in fuse box but theres no current at the fuse for the pump an some other fuses what could cause this problem?


Have you tried resetting the fuel shut off switch? Check the fuel cut out relay switch out with one of the other relays that are the same and see if you get the power. What are the other fuses for that do not have power as some wires supply multiple devices.

I have a 1989 corvette with greenwood package that cranks for about 50 seconds before it will fire, runs at a ruff idle, and after it is hot and running for awhile it will shut off and be really hard to...


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.

Getting to the tail lights of an 89 corvette


I have a 1989 Coupe and I removed the fuel door and the fuel boot and reached in through the access. You have to have skinny arms, though. It's a tight fit. I've read where some remove the inner fender, possibly the spare tire too or remove the rear fascia. Never tried those since I have skinny arms and can reach through after removing fuel door and boot.

Rough idle


The cam or crank sensor is going out when driving at high speeds. I would have those parts check, and have the fuel pressure check , fuel filter change to be on the safe side.

Good luck
