Security light not on, engine won't crank

My Service engine soon light came on Friday. Got home. Next day, car wouldn't start. Always have trouble with security light, but it wasn't on this time. I tried the 10 minutes in the on position anyway, but it didn't work.

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

The security system (VATS/PassKey) is having problems, it's typical on those cars. You can find a great write-up here: , it was the only thing that saved my Park Avenue.

2002 Grand Am wont start

Without testing we'd only be guessing ,could be any number of thing's . Is the security light lit on the instrument cluster ? A anti-theft system problem would cause the PCM/ECM - engine computer to disable the fuel injector's - no fuel squrit into the engine . Service engine soon light on ? would have DTC'S - diagnostic trouble code's stored that would point to the problem . Your best bet mite be to have it towed to a qualified repair shop.

My Honda Odyssey won't crank

It could be the starter, or the neutral safety switch in addition to the security module.
Have you checked the starter for power, and can you jumper the solenoid to make it crank ?

No, the fuel gauge not working wouldn't have anything to do with your not starting problem , probably the gauge is bad . With the SECURITY light lit , anti-theft system problem ! Service light ????? Service engine soon ? Or service vehicle ? With the light's on code's DTC'S - diagnostic trouble codes are stored . Have it checked , don't guess as to what the problem is. This would prevent the buying of un needed parts .

That would make sense, because when he jumped your car if he left it hooked up for awhile. Then he charged your battery up, so it started the next day. Then you drove to his shop and back it ran the battery down. It's easy enough to test and change alternators you could take it to autozone or O'Reillys if there is one close they can test your alternator. If you have more questions about this or if you would like to try and change it yourself just reply to this post and I will walk you through it.

You have a "Service engine soon" light on?? possible faulty IAC valve or ignition components: cam or crank sensor intermittent failure. Typically these engines experience crank sensor failure which may cause random hard starts, stalling, poor fuel mileage. Note that not all issues will happen if these components fail!! Also cam or crank failure may or may not activate the "service engine soon" indicator.

You are safe driving it for now. but should have it checked out when your Husband gets home. The Service Engine Soon light means that a Trouble Code from a sensor or compoment has been detected by the car's Computer and it need to be attended to as soon as possible. The Trouble Code can be retrieved by a OBD II (On Board Diagnostic II) scanner. Your local AutoZone can read the code for you at no charge.
