Question about 1992 Chevrolet Corsica

1 Answer

Car wont' start

When I turn the key, the car turns over fine but won't fire / start. I have been stranded and had it towed to the mechanic numerous times but they can't figure it out. They think that the towing shakes the vehicle enough to make it start.. a loose wire?

The crank sensor has been replaced, as well as the ignition module. Also, the fuel pump was checked and was fine.

Is this a recurrent issue for corsicas and has anyone solved the problem? I am scared to take the car anywhere now because it may or may not start when it is time to go.

    I do know from my own experience that if its a 3.1l, the module that the 3-coils mount to goes and causes this.The fuel pump works,has fuel pressure at injector rail,has spark to the plugs and E.C.M is good,but will not start and if you spray a little gas in the throttle body it will start and die.For some reason this module under the coils goes bad and doesnot allow the injectors to open and let fuel into the cylinders.Hope this helps.

I don't have a Corsica, I have a 2003 Suburban but I have a similar problem. Every few months or if the car has been sitting for 12 hours and the fuel guage reads less than 1/2 the car will crank and start for a couple of seconds and then die. You can keep trying but it will not run for more than a second or two. If one hits the gas tank bottom then it will start okay. At other times the car will lose power and the engine will struggle to stay running. If that happens you have to turn off the engine and then hit the tank.

We tried replacing the fuel filter to no avail and other fixes would cost a lot more so I live with it and keep the tank at least half full.

One mechanic thought that something in the tank may be coating the fuel screen and the engine had to be shut off to release it. Our other guess is that a fuel line pressure regulator check valve gets stuck and banging the tank breaks it loose.

If your problem is similar then towing the car might have the same effect as hitting the tank. When you drive the car keep an eye on the fuel gauge. My Suburban's changes readings at times. It's possible that your car thinks it's out of fuel and shuts off the pump to protect it. If your engine dies and you are coasting and you can do so safely, hit the brakes hard. That may shake things enough to help.

I've been told I have a fuel pump going bad and that banging it is only a short reprieve but it's done this for 3 years now so I doubt it.

Car brake lights won t turn off when car is shut down , was working fine before it was towed and now they wont go off. Did the tow person do something as they towed it or is it something in the car? 2007...


It is possible that the brake light connection was damaged during towing... however it isn't likely.

Understanding where the problem happens is critical. You say it happens when the car is "shut down", but is the key out of the ignition? or is the engine just off? it it actually your brake lights? or just the tail lights? some more info would help narrow it down.

Car stalled and died. Cranks but wont start all of the sudden.


You will need to see if you are getting spark to the spark plug. You can remove plug cable a d insert a screw driver and place metal of screw driver within 1/8 of an inch from metal on engine or car. Have someone try to start the engine while watching the gap for spark. Make sure you have good connection in cable. If no spark, then it may be distributed.

Car wont start turns over but doesnt fire


I can almost bet you had a certain shop do the replacement... I won't say but if the shops name starts with a F and ends with a E then They did the same thing to an elderly neighbor who lived close and It was exacly as you discribed, I took it back to them and 3 sets later, they finally got it right.. Their tires **** also!! Just my opinon... Gather your paperwork and call them and make them pay to tow it and Have them repair it... Theres been too many complaints against them for just that one issue!! Stay on them and Good luck!! You paid for a service and a part, The part didn't fail without help from bad Mechanic

2011 hyundai sonata won't start. battery seems fine. loud clicking/knocking when i turn the key. would it be the starter?


Unusual for the starter to fail on a one year old car.
You are having it towed to a dealer for warranty repairs, right ?

1998 Mazda Protoge won't start


One of two things. Starter (or starter solenoid) or Neutral Safety Switch. Check the starter by disconnecting the EFI relay, then jump a wire from the positive term of battery to lug on starter solenoid does it crank okay? If not, then check the NSS, located under the airbox, can be adjusted using the offset bolt, just a tiny bit at a time, still no start? replace the NSS and adjust as necessary.

The security light came on.


Turn off all the accessories in the car, like the ac/heater, radio, etc., then turn on the key to the run position for 20 minutes and the computer resets itself. It should start after that. I have a similar problem and my mechanic told me this and it worked for me. It still happens from time to time but I no longer get stranded for more than 20 minutes and the tow fees savesd are enormous.
