If the "check engine" or "service engine soon" light is flashing, it could be the engine is miss firing. This could be caused by a bad spark plug wire or spark plug. How old are they? After changing the plugs on my 2001 Olds Alero (at 125k miles) I noticed the engine occasionally miss fired and the "service engine soon" light started blinking. I used a timing light to determine which cylinder was miss firing and changed that spark plug wire. Advise would be to change the whole ignition wire set, but I was cheap and just changed the one wire, which cost $23 from a GM dealer. That was 14 months ago and the car runs great.

Usually its your alternator, the light comes on when your charge voltages drops below a certain level.

It is located in the exhaust manifold between the front of dash and the engine. Its a little difficult to get to and requrires a special wrench to remove it.
Good luck, let me know.

The pressure means nothing as far as the state of charge. You need to have the system completely evacuated and recharged with the specific charge weight for that vehicle. Only then can the pressures or anything else mean anything.

Oldsmoble Alero ignition security problem

It doesn't have to be the security. a dead battery won't let the car crank either. With a security problem the car will crank but not start. The security can be reset if the battery is charged and up. Turn the key on ( do'nt crank ) the security light will stay on if it needs to be reset. If it remains on leave the key on for 15 minutes around then it will go out. turn the key off and then turn it right back on, the security light will be on again. Leave the key on till the light goes out again, then turn it off then turn it back on , wait again when it goes out turnthe key off then right back on then crank the engine and it should start. With a scanner the code will be security neweds to be reset. Thia is all anyone can do to reset the security and it's what you were charged $450 for. Following directions.
