Question about 1999 Pontiac Sunfire

1 Answer

1999 Sunfire 2.2L wont start

Wont start - ran fine, shut it off, 2 hrs later, turn the key and nothing. Will not turn over. Added new parts: new ignition switch, battery and starter. Theft light not blinking - tried to reset but didnt work (ignition on 10 min., off few seconds, repeated 3 times). Just got the car, dont know anything about the radio and the theft system so I have no idea about "codes" being entered in the radio. Ran great before this, no other problems.

    Auto or stick?

    Automatic trans. Now suspecting the relay directly wired to the starter. Thanx for any help.

  • tweetybabean May 16, 2010

    Just replaced the relay wired to the starter - still wont turn over.

  • tweetybabean May 17, 2010

    Tried to start in neutral, didnt start then either. Checked electrical, starter relay is not getting power and the ignition switch is new (will check if the "new" switch is bad or not). Installed a push-button to start it, going to the mechanic on Wed. May try to by-pass the relay. Thanx for the help.

    Radio turns on, but no sound & same with OnStar. Nothing in the manual about a mute feature. Just bought the car yesterday and stereo & OnStar worked fine for 24 hrs.

Try starting it with the shifter in neutral. You might have a bad
Neutral safety switch.

    I can look up the wiring diagram if you need me to.

  • tweetybabean May 22, 2010

    Thanx for the offer but I took it to the mechanic I bought the car from - he's getting the diagram and will trace the wiring. He said he took it to the dealer (LaFontaine, Highland, MI) for the recall and the mechanic didnt know what he was doing and screwed it up (it wouldnt stay running afterward - they refused to correct this also - so he had it towed from the dealer to his shop) and he fixed the screw ups. He believes there's a pinched wire or short resulting from the poor workmanship at the dealership and will fix it at no cost.

New battery In mercedes no power

I'm not a car mechanic, but, it sounds like you might want to check the fuse to the ignition switch, and, if that fails, it might be a problem with the Start Safety Switch on the transmission. Good luck.

Battery light came on and car wont start now when i shut it off

will engine crank?? if not, recheck battery cable connections. if vehicle ran until shut off, tells me that your charging system kept vehicle running until vehicle was shut off. alternator light can be related to faulty alternator and or bad battery.

Car Won't Start

More then likely when you replaced the water pump and starter you might have installed the starter wrong or it's defective if it used to start before the repairs u did but now wont. Also, Why did your car overheat in the first place? might not be a problem with your water pump but perhaps a bad headgasket. Might wanna get that checked.
