You can put an external electric fuel pump on it, make sure you get a fuel pressure regulator to match OE fuel pressure

what yo may have is a flow pipe problem, it the pipe from the pump to the tank top. it does happen some times when you change the pump. with the engine running put your ear to the tank you probably hear it dripping back into the tank from the pump. sometimes can be herd some times not depends on how the seal has gone on the connector will give you ruff running and will not start as pressure is to low also cut out at speed. also to add when ever you need to change the pump always change the filter as you can dislodge muck stuck to the bottom of the tank and it will fill the filter more quicker.

Just wondering exactly where to cut an acces panel for 91 firebird fuel pump......yes i am going to reseal it


What Automotive College did you take a class
in vehicle butchery?

By the time you cut the body up,anyone else
would have the fuel tank dropped & be replacing
the new pump.

88 firebird doesn't get fuel, I replaced the fuel pump and did a test run and it works, I also replace the fuel pump relay, and Im still not getting fuel.


I would check the fuel pressure regulator, fuel filter, there might be a centrifugal cut-off switch. No output from the crankshaft position sensor would probly cause that. When you turn the key on you should be able to hear the pump run for a couple seconds. If not, could be a short circuit, loose connection, that sorta thing.

The pump is in the tank. The tank has to be droped to replace it. Pumps can go bad at anytime without warning. A failing pump you may not have noticed but can go bad when sitting. Try checking the autoshut down relay and fuses assiciated with the pump. Seems its not getting power or has failed.

How can i replace the fuel pump without droping the tank itself any advice in cutting access above the pump?


i do not recommend cutting above the tank you can do alot more damage.the tank is fairly easy to remove and is the only safe way i know to change a fuel pump.

cars wont start without fuel so it could always be A) fuel pump B) fuel filter C) fuel injecters dirty. any one of these will cause fuel not to reach your spark plugs and cause then eng not to start

I was driving my 91 dodge dakota 5.2 l v8, when i ran out of gas. got it towed and it has been stored for a month . i spent all day trying to get it going and it would just not turn over. droped tank fuel...


just wont turn over and not starting are two different things.
if the engine will not even turn then it has indeed locked and is in engine heaven.

if its turning over and the starter is working in turning the engine over then use a little starter spray fuel in the intake.this test will conferm fuel or ignition problem.

keep me posted
thank you

Replacement of fuel pump on 91 firebird


i suppose this would work but then u would have water and debris blowing in and it would rust out. i would rather put 3/4 copper pipe into gas opening and slide rubber line through pipe past flap into gas tank and siphon gas into buckets and lift car on jacks and get a buddy to help lower tank or use floor jack and block of wood to lower tank and not destroy floor and create new problems

1995 firebird 3.4 fuel pump is inoperative


You can but if you ever lose your prim when parked over night or a few day's you may have a starting problem. The other thing too is that your going to have to run new wire's and keep in mind where you live might give you second thought's if there is snow in your area if your going to run it in the winter. That poor fuel pump is going to be exposted. You should be able to do the fuel pump in under 3 hours buy dropping the tank. Good Luck.
