2003 Oldsmobile Alero
question = 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 the 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.

Hello and welcome.
Could you clarify something.
When you try to start, it does not crank. When you release the key
and it is still in the "ON"  position, is the security / theft light on?

question = 2002 Olds Alero, six cylinder
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
