it has something to do with the passcode security feature on the car. To fix it you leave the key in the run position for about 10 minutes unitl the securtiy light shuts off and then start the car normally. This could be one of 2 things either the key is worn or the passcode module is shot. Get a new key before you go and spend $300 on the parts. There are more answers on www.automotive forums.com If it does not start turn the key all the way to off position then turn it to the on position, at this point the security light will start flashing for between 10-15 min. Once it stops flashing or goes away turn the key all the way off then try to start it. If passcode locks you out , security light will be on. I don't think that the engine will even turn over. It could also be fuel pump. When you turn key to on position , fuel pump in gas tank should run a couple seconds (hear a hum).

If you run your cars gas tank to almost empty alot, the electric fuel pumps fail because the fuel acts as a coolent. Also check the fuse block. The fuse block on my son's car was removed and it was found to be very corroded. The engine would turn over, but not start. The ODB II reader could not read any codes. The problem was worse when it rained. There must have been a leak that caused water to corrode the fuse block.

This could be the voltage regulator. Both the positive from the battery and the starter would be connected to it.

My sunroof quit working too as you described. Turns out it was the overhead switch that went bad. Had mine replaced for $95 installed. Works like a charm now!

Do a fuel pressure check. I had the same problem and it was my fuel pump.

If it turns over but seems to buck & choke you may have the wires on in the wrong order. Did you do them one at a time? Does it try to start?

User Avatar

No. It is highly dangerous and could cause an explosion and serious injury.

If the car won't start it is usually the battery, starter or could be the altenator. What are the symptoms when you try to start it, is there any power?

User Avatar

The standard procedure is to admit your initial hypothesis turns out to be wrong and then proceed to explain why it was wrong and what really happened. Science is all about learning from your mistakes.

it might be the alternator, try and get it tested. if the car won't start the battery will also be dead, you could replace the battery and drive it to get the alternator tested at an autozone or advance auto parts for free.

I currently have an 2001 Alero and it has 200800 miles one it. I have not had to replace the engine or transmission. The only issue is the fuel injection. I pay that is all that goes wrong.
