On that particular model, you'll have to unbolt the rear end enough to lower it to gain access to dropping the tank. Use a jack and lower it about 6 - 8 inches. Once you're done that, you'll be able to remove the gas tank and access the fuel pump to replace it.

    Run a jumper wire off of the battery and remove a little of the insulation off of the power wire to fuel pump. Touch the wire with your jumper and the pump will either hum or it will not.

Fuel pump pumps when cranking but does not prime, also the injectors are not opening.


There should be a valve on your injector fuel rail. looks lie a valve stem in a tire. , depress the valve and see if fuel sprays out. you may want to get a fuel pressure gauge to check and see what kind of pressure you getting if any at all. ,

The fuel pump on my 1995 Firebird Formula quit running. I've even tried feeding 12v directly to the grey wire on the fuel pump relay and it still doesn't run. Can a generic fuel pump be installed...


No, the fuel pump in the tank needs to be replaced. It's not too bad to remove the tank, hopefully you don't have much gas in there though.

Good Luck!

Cranks but won't start fuel pump not coming on


put a small amount of fuel in the intake near the throttle plate then crank and see if it fires, if it does then it's a fuel problem, if it does not fire then pull a plug wire and put a philips head screw driver into the plug wire hold it 1/4 inch away from a good ground then have someone crank it over, you should see spark and it should be blue, if not then you have a ignition problem a bad coil or cam sensor but need to know what you found out on the two tests I told you first to give you a direction to go.

1989 Firebird won't start unless gasoline is sprayed in throttle.


your electronic fuel injectors should have a similar connector as another make sure you didn't connect the wrong piece to you electronic fuel injection wires, the connection should be a 2 hole plug and should run from the coil to the intake
