Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
hello. there is not any fuel cut-off switch on the cavalier. if the fuel pump isn't running... then it's 1 of 2 issues... the fuel pump has failed... or the vehicle is in "theft mode".
if you crank the vehicle and it starts, runs for a second or so, then dies... it's in theft mode. what you can do to get it out of theft mode is...
if it starts and runs normally... you will have to have the lock cylinder and theft sensor replaced.
NOW, if what i've stated above doesn't apply... you can try another "trick". get someone to try to start the vehicle... while the assistant is cranking the vehicle... using a hammer "tap" on the bottom of the tank and see if the pump starts to operate. if it does... then the pump should be replaced.
please reply with your findings.
I Appreciate your knowledge and will try this exercise on the car. This is our daughters car, and she used all she had, plus some we had to give her...;.just to tow the car. She cannot afford to replace the pump at this moment, if it needs replacing.
Thank you very much for your help.
I will accept your answer, although you more or less confirmed my instincts. We did ban gon the tank, and nothing. My daughter was on her way to a birthday party in another state. So, you can see why it was such an expensive tow. Anyway, i believed it was the pump..from the start. We will try this exercise you suggested, and who knows....however, she did go over some railroad tracks and then the car died at the light right after. So thinking maybe the jarring caused it to finally go out, when maybe it was going to go out anyway. I just wish she had been closer to home when it happened. Female out stuck on highway.......far from home...not a good thing ever.
Thank you so much.
Oh, and I don't see the accept button yet, but will keep checking. When i go to "my questions" it still said "waiting for expert reply"..even though you already replied.
you can accept if you'd like on this posting... if you need any further assistance let me know and i'll be glad to help you.
as for the railroad tracks... it is a good possibility that the jarring did cause the pump to fail... but first i'd check over all connections at the battery and the fuse block under the hood to make sure that something, other than the pump, didn't get "jarred loose"... like a fuse or a relay.
