I have a 1995 Oldsmobile '88 that has several problems. The first noticeable is that it wont start up, the engine cranks but won't start. Also, the power locks and power windows don't work but the radio and lighting does. Added to the power locks when I press the lock/unlock button I can hear a little buzz coming from the doors, guessing the little mechanism is trying but can't.
This is actually the second time this has happened to me, the first time I had it towed to a mechanic and he replaced the connector for my battery's positive terminal since it was corroded and that work fine for about 3 weeks until now. When I checked under the hood, I noticed the part he replaced was rather loose in the terminal so I tightened it, but that obviously didn't fix the problem.
Other things to note I guess would be that both times this has happened the car initially started and I could drive for a bit, then the car would turn off. Now it wont start at as mentioned. Also the mechanic's initial thought was that the connector wasn't able to make a good connection due to all the corrosion which was why he replaced it. And the check engine light does come on when I have the key in. Hope, this helps you guys help me figure out how to get running again. Thanks.

If the check engine light doesn't come on when you turn the ignition on, that probably means the ECM isn't powering up. You need to trace this problem by first checking the power and ground circuits to the ECM. If it is a ground or power problem, you need to trace it to the source of the problem depending on which circuit is missing power or ground.
You'll need a schematic or ECM pinout diagram showing which circuits on the ECM are power and ground feeds.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

The check engine light does come on when I turn on the ignition. I began checking the grounds and from the ones I could easily trace they were fine. I'll check back on it later to find the others.
Edit: Worked on it more today and noticed the alternator was cranking more slowly until the car ultimately lost power. It now has no power to it what so ever, I will try and get the battery tested. I have also forgotten to mention that the problem with no starting nor power locks, etc. happened both times after initially starting the car driving it a short distance then the car engine stopped along with power locks and windows. I have a hunch it might be the alternator gone bad. It is the original alternator to the car too.
