SOURCE: my car wont start some times it does some times it

If the battery is good and the alternator is charging, check to see if you are getting good voltage at the starter. It could be the starter or it could be your battery cables are needing replacement. I assume you have cleaned your battery terminals....that's actually the first thing to check.

The reverse light switch on the 1994 Pontiac Grand Am is part of the Neutral Safety Switch or also know as Transmission Range Switch.

One reason GM vehicles dont start, especially when the weather changes isdue tofaulty antitheft systems. Next time this happens, look for a light on the dash that says secury or antitheft. Picture might look like a car with a padlock thru the window, If you see any of these lights, that will explain why it doesnt start. This link explains.

Won't start. Turn the ignition and nothing. The engine light comes on and the auto theft light comes on for a few moments and goes off. I tried the couple things suggested in the owners' manual...

if nothing happens when you turn the key the problem is most likely the ignition switch and housing(had mine replaced 3 times already. firstr time at 12,000 miles) what you can try is hit key with rubber mallet while trying to turn but this would only be to get it started so you can drive to a chevy dealer(dont waste your time at any old repair shop for this). Hope this helps.

Hello i am experinceing some problems with my 2003 toyota corolla first my run light stay on with the key off the key out of the ignition i gather from forums thats the head light switch since it only...

It sounds like you are suffering from a bad case of "Killed The Battery" The ignition switch will not turn your headlamps off if you leave the light switch turned on. This is a problem I see all the time with "Auto" headlamps. Most people turn the headlamp switch to "Auto" and leave it there. This is fine. The headlamps will stay on a minute or two after the ignition is turned off then they will shut off automaticly. What happens is that the headlamp switch gets turned to the "On" position and when you get out of the car you expect them to turn off automaticly but they don't....Dead battery! Then there's the case where the headlamp switch itself lies to the body computer (The guy in charge of turning the lights off) about which position it is in...You have no idea that it is doing this...Dead battery!
The radio is most likely inoperative due to the battery going dead. It is probaby waiting for you to enter the security code to unlock it. If you don't know the security code you will have to take it to the dealer to get them to unlock it for you. (The antitheft system thinks you were trying to steal the radio when the power went off) The clock is going to be off because it has to be reset just like the clocks at your house when the power goes out.
