Hello all, Will a faulty fuel sending unit cause the fuel pump to not engage? I replaced the fuel pump recently and I know it is good. (when I put power to the harness the fuel pump kicks in) but I get no pump when I turn the key. I have a feeling that the sending unit is toast, because the fuel gauge is reading wrong. I am trying to track down if that could cause this or if it is the relay. Thanks all.

Re: fuel sending unit question
OK so I replaced the relay and nothing changed. I am finding that I am not getting power to the harness at the plug that goes to the fuel tank. I have unplugged the harness at the body (above the axel) turned the key on and tested with a test light. Any thoughts would be helpfull. thanks againRemember that sometimes, silence is the best answer.<br />Warren White<br />1996 PoloGreen Coup <a href=\"http://vampyr.settanni.net/\" target=\"_blank\">http://vampyr.settanni.net/</a> <br />\"Jealousy\"<br /> CTFBA member of the month Sept 03 -
Re: fuel sending unit question
Have you checked the fuel pump fuse? When you say you "put power to the harness", are you meaning that you jumped 12V to the harness that goes right into the fuel tank? If so, then it seems to me that you have either a blown fuse or a broken wire/bad ground in the circuit. This may also be causing your sending unit issue. I would not think that the pump working or not would be affected by the sending unit transmitting a certain level of fuel.
Since you already tested the harness with a test light and found that you have no power, you need to trace the problem back to the fuse panel. So I would (1) check the fuse. If the fuse is good, (2) check to see if you are getting power at the fuse. If that checks out, (3) see if you are getting power at the relay. If you are getting power at the relay, then you may need to check the wiring between the relay and the plug at the back for breaks or corrosion. As a last resort, run new wires and splice them in.2002 Silver Firebird A4<br />T-Tops, Leather, Y87, W68, Chrome Wheels<br />Bone StockComment

Re: fuel sending unit question
thanks Rob, I actually just looked up the wiring diagram to do just that. I am NOT getting power to the inbound side of the relay, so it is upstream of there somewhere. The fuse "LOOKS" good but I think I might replace it anyway just to be sure. It is odd because I do have power to the fuse. I am going broken wire hunting when the rain stops. Again Thank you VERY much for the help.Remember that sometimes, silence is the best answer.<br />Warren White<br />1996 PoloGreen Coup <a href=\"http://vampyr.settanni.net/\" target=\"_blank\">http://vampyr.settanni.net/</a> <br />\"Jealousy\"<br /> CTFBA member of the month Sept 03Comment

Re: fuel sending unit question
Did you ever completely miss something and feel like a total *** when you found it? All of the trouble I have been having (minus the fuel pump) was due to a missing fuse.. AAAAARRRRGGGGGGG I have been checking the wrong fuse all along. Now I feel like a complete moron... Oh and apparently I have an indestructible camaro.. Sitting for almost 3 years, fuel pump replacement fresh fuel and a new fuse and it fired on the third crank..Remember that sometimes, silence is the best answer.<br />Warren White<br />1996 PoloGreen Coup <a href=\"http://vampyr.settanni.net/\" target=\"_blank\">http://vampyr.settanni.net/</a> <br />\"Jealousy\"<br /> CTFBA member of the month Sept 03Comment
