It started and ran for several days with no problems. Then yesterday it would crank but not start again. I turned the key to on and I did not hear the fuel pump prime the system. I did hear a couple of clicks under the hood. Also when I turned off the key I heard a series of about 6 clicks right in the engine area. I checked the fuel pump relay and the fuses under the hood and everything was OK. Is this a PK problem, an ignition cylinder problem, or maybe a BCM problem? Is the fuel pump acting up? When I cranked the engine the Security light stays on for just a few seconds and then goes out. If this is a PK problem will the fuel pump still kick on or do the fuel injectors just cut out? Do I hear the F/I clicking under the hood when I turn the key off? I never heard this before. Any help would be greatly appreciated

Welcome to AF
It sounds more like a engine starting running problem.
You have to have spark and fuel pressure first thing to check.
Try running a post in the Alero forum for help on it.
If Triped.
The anti theft system cuts injector pulse within or after a couple seconds of engine starting.
If light comes on with a key on buld check and then goes out it it should be OK.
