Question about 1991 Chevrolet Camaro
I have a 1991 RS Camaro that, I believe, needs a new fuel pump. It needs a few other things, but I think that the problem it is having is because of the fuel pump being bad.
Here it is: My car wants to start, but all it does is just keep trying. If I spray a little starter fluid into the throttlebody, it will start a little bit, then it will stop after it burns up the starter fluid. I look closely, and the fuel injectors aren't shooting gas into the TB. If this is a fuel pump issue, awesome. My Fiancees car was having the same problem, her dad took it in, and they put a new fuel pump in, and it works...so...
So, my question, is how do I put it in. I heard something about taking out the gas tank, and that really sounds like something I would have to do if I had all day and a bunch of tools that I don't have. I don't know where it is, or how to put it in, if you guys could help, it would mean a lot.
My car gets better gas mileage than the family van, and I am tired of shelling out money for gas every 20 miles.
If you could help, I would really apprecieate it.
Hi yes you have to remove the gas tank to get to the pump.once tank is out remove ring holding the sending unit.then remove unit replace pump then reinstall in tank then put tank back in. and try to start.

First of all you will only have voltage for 2 seconds after key is turned on from the fuel pump relay. after that when you begin to spin the engine over oil pressure then builds up and closes the contacts on the oil sending unit causing the fuel pump to stay powered up as long as it's spinning or it's crunk and running.
so while you check for power on the tan with white stripe at fuel pump , have someone bump the engine over, if you have power up until about 2 seconds after they let off the key then check ground to pump if it's ok then you'll need a fuel pump.
If you don't have voltage when it's spun over then check the red wire coming from the oil sending unit the same way you checked it at the fuel pump.
If you have voltage then check inline fuse beside the battery. if fuse is'nt blown then check for broken wire from there to fuel pump.
If you don't have voltage from red wire at oil sending unit then check for voltage on orange wire at sending unit, if you have voltage on the orange wire and not on the red wire while someone is spinning it over then replace the oil sending unit.
If you wanna do a quick check that makes sure your relay isn't the problem Go to your 12 way diagnostic connector under dash by stearing wheel. and touch a battery hot wire to pin G if relay is ok the you should hear the fuel pump come on.
