Disconnect the fuel pump connector and install fuse to see if it blows. if not then the fuel pump is drawing too much amperage causing the fuse to blow.

SOURCE: replace fuel pump on a 2001 chevy cavalier

First, if your car still runs, pull the fuel pump relay, and start your car, letting it run until it dies. This will depressurize the fuel system. Then you must support the fuel tank, and take loose the straps that hold it up. Slowly lower the tank until you can unhook the tank filler hose and overflow hose by taking the clamps off and sliding the hoses off. lower it some more, and unhook the fuel lines; they require you to insert a special tool around the edge of the connection, however this can be improvised with screwdrivers or a piece of plastic or metal bent into a C shape. Next unhook the wire connection. Once you get it down, it's easiest to empty as much fuel as you can; as this will help you get it back into place. The fuel pump is inside the tank, which locks into place with a 1/8th turn. You will need a hammer and a brass punch for this job, as it needs to be tapped around to unlock. It will then lift out. Compare the two pump assemblies. The inside parts can be slightly different, but ensure that the fuel lines are IDENTICAL and the wire connection is IDENTICAL. The new one will come with a new silicone seal. Ensure that you don't put the new one in in such a way as the float doesn't bind, otherwise you'll be doing this procedure again if you don't like guessing how much gas you have. This can be a challenge to wrestle with putting the new one in, as you have to push it down to compress the new seal, and turn it to lock it. Once you get it started, you can let up and use the hammer and punch again to tighten it the rest of the way. Next, put it back together just as you took it apart, and don't forget to hook up the wires, hoses, and fuel lines. No tools required for the fuel lines, they just snap together. Once everything's tight and hooked up, put gas back in it, and if you haven't already, put the fuel pump relay back in. This you can do as soon as the car dies, and is completely optional if the car won't run at all. You are now ready to start it up, but turn the ignition on to the run position, wait a few seconds for the pump to pressurize, and then start it. Have fun, and feel free to ask any questions should you have any.

Cavalier '99 the fuel pump fuse blow only if the car is in drive and press the break pedal or pull the hand break, if I run the car on drive is OK if I do not put the brakes. On reverse and park i

Thats wild.
The fuel pump - injector circuit is on one fuse and the brake circuit is on a different fuse. I can't think of a way the two would be connected other than something wrong with the fuse box.
If the pump fuse blew when you hit the brake pedal, it could be something shorted in the harness, but that would not explain the parking brake.
If there is nothing wrong with the terminals in the fuse box, and no sign of trouble with the wiring around the brake pedal, you may have to hunt the wiring harness back to the pump to look for bare wires.
It might be easier to run a new wire from the pump relay to the pump outside of the main harness.
They make circuit breakers that can take the place of regular fuses, but that would only be a temp fix.

My 1999 Chevy Cavalier's fuel gage does not go above quarter even with a full tank. Why?

in my experiance with chevy's, it's the fuel pump that they use. most of the time you can simply go to a shop and have them adjust the float inside the fuel tank and you'l be fine, it is generally the same price as an oil change. what your describing could be answered by this. i hope this helps.

L999 Chevy Cavalier keeps blowing fuses and won't start

you have a SERIOUS electrical problem. - '.
BUT which fuses keep blowing - that is where we need to start.
1. is it the ignition circuit. - - does starter motor turn over when you trun the key.
2. is it the starter relay circuit.
3. is it the starter motor circuit.
4. is it the computer circuit. - - do you have fuel pumping to the engine and cylinders.
5. none of the above. - - do you have spark at the spark plugs.

1991 chevy cavalier- stopped running going down road. Replaced fuel pump and fuel pump relay-ran for two weeks and the when making a stop,cut off again and won't start and is blowing the fuel pump fuse...

Sounds like a short between the fuse panel and the fuel pump relay. This can be from the fuel pump relay itself through an exposed bit of wire, or even a defective relay which seems to happen more than most times. Check the wiring to the relay and wrap or tape anything where bare wire may be exposed. Disconnect relay and try a new fuse. IF the fuse doesn't blow, then the problem source is the relay itself that is defective.

Hope this helps!

88 chevy cavalier only starts when i poor gas in the throttle body then it runs fine

Sounds like you have one of two problems. either a clogged fuel filter( the easy one), or a fuel pump problem. The fuel pump problem could be as simple as a blown fuse, bad wire connection, or it could be a bad pump. Hope this helps.
