Hey guys,
I did a search and nothing of use came up. I would appreciate your help, I'm right in the middle of changing my fuel filter on my 1992 V6 3.1 Liter Camaro. As you know, the fuel filter is under the car and inline with the fuel tank. Between Hanes, Chilton's and the factory service manual, none of them tell me the correct fuse to pull to relieve the fuel pressure before I remove the fuel filter. I'v pulled the obvious fuses but the car still runs, althougth a bit rough. So, if you could tell me the correct fuse to pull I would greatly appreciate it, and also how long does the car run before it dies on its own after pulling the fuse? I let the car run for about 3 minutes and it still didn't die.


Thanks.

James

 

This is easier... Jack up the car so you ca get underneath the gas tank, if you look up at the front of the tank you'll see a connector. This is the fuel pump connector... Unplug it here & you're good to go

 

Thanks for the input Z2point8, however I have a follow up question. I believe you are saying to pull the gas tank connector and then start the car and the engine will die shortly after, thus relieving the fuel pressure. Is this correct?

Thank you.

Actually....The fuse for the Fuel pump is mounted right near the battery on your frame. It is a blade fuse by itself and is VERY easy to get to. Why jack up the car when you don't have to??? Your car will turn over and possibly crank(doubt it). Turn it over a few times to relieve pressure off of fuel lines and then you can do what you have to.

1fastformula,
Thanks for the input, however all three of the books I mentioned above describe pulling the Fuel Pump fuse from the fuse block under the dash by my feet. Are you sure about your advice?

Thanks.
James

 

My 89 was a 350 TPI (before crate swap)...I am not sure if the engine difference matters with fuse placement. Let me tell you a quick story......I was at work and damn car would not start. Thinking it was the connectio to bettery, I cleaned all the posts and noticed a wire going to my wall. Thinking nothing of it (DOH), I did not connect it back and the car cranked, but did not turn over. Went home (very hard to leave car there) and checked out my Hayne's book. NOTHING!!!! Went back to work and a FORD owner told me that the wire was probably your power to the relay to run pump. I rehooked the wire and VOILA.....Car cranked!!!! If you are still not sure of my advice, then pull your fuel pump relay. Driver side has two relays....pull both if you want, but it is the first one.

and take it from me..Haynes is good for telling you numbers like gaps,compression,etc.etc.etc. When it comes to following the instructions.....Take caution

Since you have to put the rear of the car up on stands anyway to get to the filter, it's really much easier to just disconnect the fuel pump at the tank. Crank it over after it's unhooked and it might or might not fire, either way crank it for a minute or so. This will relieve your fuel line pressure.

 

There is no fuse you pull to relieve pressure. Your charcoal filter is a vent and number two you crack the fuel cap to relieve pressure after that there is no pressure. You may have a little a bit of fuel come out but thats fuel that was in the filter. Now you could pull the relay under the hood and the actual fuel fuse but as long as the car isn't running and you don't have the accesory on it won't matter. If you really can't find anything disconnect the battery. The fuel pump relay should be the second one in on the firewall from the drivers side. Or if you want to be really tricky just remove the wire to your oil safety switch and your car will start but not run, but I don't recammend it. Hopefully this can help. Hopefully this helps. Got any further questions email me or something.

 

I never bother pulling the fuse, I just take off the filler cap and change the filter, just a little fuel will come out, liquid unlike air will not compress, so the instant the line is loosened all the built up pressure will be relieved very quickly after just a few drops of fuel leaks out.
