2003 Oldsmobile Alero.
I came home from work and my car was working
fine when i turned it off i forgot to switch it to park
and after i turned it off i then switched it to park.
Then a few minutes later the car wont start and
the engine wont even cranks over.

I thought it was going to be the battery but all of
electrical stuff works. When i turn the key
everything is off but the security light, once i let go
off the key all the lights come on including the
radio. You cant here a thing when you try to start
it, so i wonder if theres an engine kill or
something. Thanks and please write back as
soon as you can.

Could you clarify something. When you try to
start, it does not crank. When you release the key
and it is still in the off position, is the security /
theft light on?
Problem with my 2002 Olds Alero 3400 V6.
Changed Battery, Brakes, Oil change. Can't figure out what it is?

Car will turn over but will not start? Battery's been tested, spark
has been tested, electrical system has been tested and is not
reporting any errors, you can hear the fuel pump hum when the
key is in the on position. The car will start sometimes and not
others and it seems if you leave it awhile and try again, it starts
again. There are no indication lights for anything on the dash
board panel. Tried removing the gas cap and starting it and it did
not work last night, but then after that, we put the cap on and it did
start..could it BE a gas cap issue? Or maybe the fuel filter itself?
Not sure if that would cause a fail to start or not...need some
suggestions pleeeeasse! Thank you.

No, the gas cap cannot cause your
Oldsmobile to not start. You
may have a no spark problem caused by a bad ignition module or
crank position sensor. You need to find out if there is spark at the
plugs first of all. Then if there is fuel injector pulse signal. If you are
sure the theft light is not on, then these are the first things to
check out.
Oldsmobile Alero Will Not Crank Over Or Start

Question: I have a 2002 Oldsmobile Silhouette that will not turn
over with the key..but will turn over, start and run when using the
auto start..not sure what to do...  

Answer: Do you know if the auto start is the factory start system
or a non-factory auto start and alarm?

A non factory start...I have also checked all the fuses.

OK. This system bypasses some parts of the factory system.
You may have a security system problem, or even a problem in
the non-factory system. When you try to start it with the key, and
then let go of the key, is the theft or security light on or blinking?

The security light comes up on the display but does not stay on
or blink.

OK. I would suggest removing the aftermarket system. That can
be your problem. We have seen the modules for these systems
go bad and not allow the car to start normally.

I will try that. really perplexing as I have not seen this before.
Thank you for your time..I do appreciate your help.

Your Welcome. God Luck.
