Is there any way of checking the relay on a 1993 z28 camaro. When i got the car i thought the pump was bad so today i changed the pump and it still doesnt work. Then i hooked the old pump straight to the battery and it works. So know i am hoping it is the realy or something small if you have any ideas let me know.I would appericate any help at all.

Also on the pump wires. What one is what? There is a grey, purple, and then a black. which one goes to the pump and then which one is for the gas gauge.

Haynes manual has the answer to the questions. ;)
Purple: Fuel Level
Gray: Fuel Pump Prime
Black: Ground
Should also be a Dark Green/White and a Pink wire going to the relay. DK GRN/WHT is the pump relay control from the PCM. Pink is the power source for the pump (fuse 5: PCM IGN).
See here for a picture of the relay: http://shbox.com/1/fuel_pump_relay.jpg
Either replace the relay, or use a test lamp to see if power's flowing through.

Thanks alot. I bought a Haynes manual this morning. And then i pulled my pump and noticed one of the wires had pulled out of the plug inside of the tank. so i plugged it back up and now it runs fine.Comment

I’m new. I actually don’t own a Camaro or firebird. I do have a 2000 Camaro 3.8 fly by throttle and 4l60e. This is installed in a 1980 Triumph TR7...1 week ago -
