duh sorry 04 olds alero 140000 4 cyl 2.2

The service engine light will be on until the engine starts. Then it will go out if no faults are detected.

Does the engine start and stall, or does it just crank but not start?

Customer: replied 4 years ago.
yes it will crank but will not start

Since the plug are hard to get to on this engine, have you tried starting fluid while cranking the engine?

Customer: replied 4 years ago.
starting fluid into the ir air cleaner port. not starting still. no spark i think

The most common problem on the 2.2 engine is failure of the ignition control module. You can check AC voltage signal into the module on the Yellow and Purple wires from the crank sensor while cranking the engine. You can also make sure you are getting 12 volts DC into the module on the Pink wire with the key on.

so far so good one more question please. if there is no power to the ign. control mod is it a bad ign. switch

If there is no power to the ign mod and all the fuses are okay then yes, this would indicate a bad ignition switch.
