Can anyone please help? I am having problems. My 01 sl2 wont start and the gauge says that the car is empty (before this problem, everything was working fine). I know that I have more than a half tank of gas, the car continuously turns over but wont start. I replaced the fuel pump and still it wont start (not to mention that the tank was more than half full at the time). I checked all the fuses and relays and everything seems fine. I am not even getting gas pumped to the filter. Does anyone have any suggestions.

The fuel pump and the fuel gauge sending unit are both in the tank. Check the connector there. You'll probably need to drop the tank. Obviously, your fuel pump is not working. Confirm you're getting power to it, if you are getting power to the connector at the top of the tank but no fuel is flowing, you must have a bad pump/sending unit. Or, something came lose inside.

Thanks for the info. If the sending unit goes out would that stop the fuel pump from working? I replaced the Fuel pump with a new one and the car still does not start. I am guessing that it isnt getting power. Could the BCM be bad? I have been reading a few posts about the BCM.

So if you turn your ignition to the on position.. do you hear the fuel pump run.. buzzing.. for a second or two.. "turn the car radio off"... if not.. go back to the fuel pump.. if there is go under the hood and follow the fuel line in.. you will see a Schader valve.. with a "rag of cloth" to catch the fuel...if depressing.. if there is fuel... your next option is to see if you have spark at the 1/4 coils... if there is none... change your CPS .. crank position sensor..

I changed the Fuel pump, but I dont hear it buzzing. I know everything was connected correctly. I even tested the old pump and it works. I checked all the fuses and relays, they all work. When I dropped the gas tank, it was full of gas and the fuel guage read empty. I have no clue what I should do next..........any help would be great.

not to say this is your problem, but if the pcm is not communicating with the instrument panel cluster, then the gage will read empty. make sure you have no fuses open, (all fuses, pcm, ign., etc...), and have someone check your bcm and pcm for codes or lack of communication.

Get a test light and have someone turn the key on for a few seconds while you stick the test light in each prong of the connector. One of the prongs should get hot for a few seconds each time you turn on the key. If not you need to find where you are losing connection.
