Fuel System I have a '91 Firebird Formula, and for some reason I can't get the fuel pump to kick in, The pump checks out ok, and so does the relay and the fuse. My question is, could it possibly be in the ignition switch, and if so can it be bypassed until I can get a new switch?

There are 2 fuse boxes. One under the hood (Cover removed)

The other one is under the dash driver side near the kick panel. The power for the fuel pump is through the ignition fuse and the PCM that controls the fuel pump relay.

pull the fuel pump fuse and relay it wont come on then. hope this helps

Check in the engine compartment relay box. See my tips at http://www.fixya.com/cars/r6022358-relay_check and let me know if you have questions

It sounds like you may have burned out your fusable link. It's a special wire that comes off the starter solennoid and is designed to burn off in the event of an overload. DO NOT REPLACE IT WITH REGULAR WIRE, THIS IS A LEADING CAUSE OF CAR FIRES.
You will want to check for what caused the overload condition that caused the fusable link to burn out in the first place.

i have an 89 formula firebird replaced fuel pump this morning and pump only is getting 6 volts instead of twelve. can't hear pump either..what do i do next

check your wiring from relay to fuel pump commector. possible cause is 2wires rubbing together causing the relay to kick in and out. if your wiring checks out ok then the problem will be in the fuel pump trying to short out. use ohm meter and test light to check wiring and pump.

The fuel pump relay is located on the engine driver's side of the firewall. It is held by a bracket with two other relays-primary and auxiallry fan. The fuel pump relay is between the 2 relays. It should have a test lead extending from the connector.
Good luck and thank you for using Fixya

the relay for the fuel pump is in the engine compartment,you can try to remove it and put it back in,while the key is in the run position.if you hear the pump working try turn ignition off and on untill you develop fuel pressure.

Check your fuel pump relay

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.
