Question about 1985 Chevrolet Citation

1 Answer

Car won't start

This car still won't start. It has a new battery, and we have replaced the fuel pump, two relays, coil, distributor, ignition control module, plugs, and the fuel filter. Engine has spark, and will start with gas poured into the carborator, but will not run after fuel is gone from the carb. There is no power to the fuel pump. Tried looking for a rollover switch in the trunk, but there isn't one. This is a daily driver for our son so there is limited money available for repairs. We are VERY frustrated! Any suggestions would be great.

    Yes the fuel line was disconnected and there is NO flow from pump. No change when choke is fully closed.

  • oto_six Jan 05, 2009

    Will try your suggestion about safety neutral switch. Fusible link is ok, changed it out. Fuel pump connector/wires fairly easy to get to, tried unplugging it, ran a jumper wire from the battery to the fuel pump connector and the fuel pump ran, but when it is plugged back in to the wiring harness, there is no power to the pump.

  • oto_six Jan 05, 2009

    Is the fuel pump on a variable speed? Would this make a difference in wiring it directly?

  • oto_six Jan 05, 2009

    The pump is in the tank, and cannot see a fuel pressure regulator in the line.

  • oto_six Jan 05, 2009

    Thanks for looking into this for me. I will be back tomorrow night to see what else you have as suggestions. I am fine with the wait, since I really need to get this running.

  • oto_six Jan 06, 2009

    We weren't able to look at the car today, it's in a relative's garage in a nearby town. Winter weather makes it tough to work on the cars outside. Hopefully work will be done early enough tomorrow for us to get a chance to work on the car. Thanks again for your suggestions, and I will post as soon as I can answer your questions.

  • oto_six Jan 10, 2009

    The car is running!!! My husband hot wired the fuel pump to be sure it was good and it is working. He traced the wiring back, and found a section of wire that was corroding. He replaced the bad section of wiring and the car is running smoothly.



    Thanks so much for your persistance in helping us with this problem. Our son (and mom the temporary taxi driver) are very happy that he has something to drive again.

  • oto_six Jan 10, 2009

    Umm, taxi service now focused on my other three children... two of them are teenagers with driving permits and one just turned ten. I think taxi driving will be part of my life for quite a while to come.

    You disconnected fuel line at carburetor and checked for flow from pump? Does it help at all if you hold the choke fully closed?

Only other 2 things that come to mind are safety neutral switch, try starting in different spots, neutral, hold key to start & move shifter slowly through the gears. Other is fusible link under hood may be bad. How hard is it to get to fuel pump connector/wires?

    If it were me, and the fuel gauge is on a separate circuit, I'd run my own fused jumper wire from an open cavity in fuse panel, that is only powered with key on. I'm not trying to be smart, but if you've checked & verified that all fuses, links and relays are good, you could spend forever chasing this down. Any schematics I could find, don't show anything other than a relay for fuel pump, and you've tested them power in & out right? Did you by chance try to follow power out wires from relays, to see if you could follow any of them back or down and back toward the pump, or at least look for same color wire at pump connection?

  • Mike Butler

    Do you see a fuel pressure regulator anywhere in the fuel line?

  • Mike Butler
    Mike Butler Jan 05, 2009

    Just double checking, is that pump in the tank or in line.

  • Mike Butler
    Mike Butler Jan 05, 2009

    So i'm thinking there is a return line for excess fuel back to tank, which tells me it's unregulated continuous flow, probably 5 to 10 psi, max. with it being carbureted. Something just struck me though, we/I need to check and see somehow, what if any, safeguards there were in that system in case of an accident, like a trip switch or something for that pump. That may be what we should be looking for, or at least confirming whether it does/did or not. I hate to make you wait but I will speak to my buddy at work tomoorow, who was with GM for quite a few years up until recently, and drill him on it, and get back to you tomorrow. Sorry about the wait, unless another tech jumps on to confirm my suspicions.

    Well, it turns out the guy I wanted to talk to isn't back until thursday, but after looking in to info on the pump, I did find that some of those pumps are wired through an oil pressure switch. That may be your case. If it's wired though an oil pressure switch, im guessing that perhaps, your oil pressure switch is faulty, or it just hasn't run long enough to build the oil pressure up enough to activate the switch. How long did it run, when you powered it with jumper wire, long enough to build up oil pressure? Does it look like maybe your oil pressure switch has an extra wire or 2? If you go on the autozone.com site , you'll see that they list a fuel pump for that car that requires use of an oil pressure switch. That makes sense on what would shut pump off in accident situation. Engine quits, so does pump. Did you by chance buy it at autozone?
