93 cavalier fuel pump

I have a 93 cavalier 4cyl station wagon. Is there anyway to access the fuel pump without dropping the tank? They want an arm and a leg herte in Indy to change it out. My problem is after driving for awhile it stops like running out of fuel. If I keep pumping and keep it rev'd it will keep going. After sitting for a short period of time, it starts but does it again.

The pump is in the tank so there is no way to pass that up. And IF you keep pumping it, it will do nothing because it is fuel injected and the pump is what does the pumping. It is not like a carb where you can do that. So your best and only bet is to just get it fixed.

its really not a hard job, get a haynes manual or somthing similar and it should tell u how. Reallyall there is to it is disconnecting the two holder straps, all the fuel lines, and the electrical connection for the pump, than u drop the tank and pull out the pump.

Change your fuel filter while you're at it, maybe it was stopped up and the pump went-out trying to push it through. My fuel pump has been humming/whining for a few years and I know it's going to go, someday, but I think by changing my fuel filter when it first started I slowed the wear on the pump.

Changing the fuel pump is actually quite easy. I got the sedan tho, not the wagon. In other words, i'm not sure if the tank is in the same spot. If you got an air hammer, this is the best way to do it. Take out the back seat, then take out the padding and that underneath to reveal the bare metal. On the sedan, the pump is up closer to the front, so using the air hammer, cut out a square close to the edge where it curves down. Its kind of hard to explain. Anyways, when you cut it out, the fuel pump is right there. Just simply pull it out (make sure u vaccuum around it before you do so your not getting any dirt in the tank) and then drop the new one in. When you close it back up, make some brackets with tin or something. I did that, then welded them in. If your welding, be Extremely careful. I took many percautions when i did so. Anyways, thats how I did it. I'd say it took about 2 hours total. Had i of taken it into a shop, it would of been days, plus all the unneccesary costs =P

wow you did way too much work. i've replaced fuel pumps on a few of my friends cars and it only took about an hour and a half. well my friends truck took a long time but that was a different story, not our fault. i cant imagine it being any more difficult on the cavy only that there isnt any room under the car. i'd just jack it up and put it on floor jacks. but thats just me.

Well. on my car, the bolts that held the straps on the tank were all rusted. And i didnt really want to grind them off or anything. Not to mention, i was doing it with almost a full tank, since its safer. (Its not the gas thats flammable, its the fumes. empty tank = more fumes) Anyways. So my only option was to do it that way. It wasnt all that hard. I had nothing else to do, so i wasn't in any hurry.

as long as it turned out ok, just seems a bit over done. when we replaced the pump on my friends truck he had a full tank of gas...that sucked.talk about a heavy S.O.B. i think jeeps are the easiest cars to work on yet. we replaced a fuel pump on a jeep in like 45 minutes. and tht was at night.
