To start off the car is a 95 Sunfire with the 2.2 and a 5spd. I need some in site as to what this can be. I was driving the car yesterday and all a sudden my battery light came on and stayed on for about a minute. The light then went off and after that my lights got dim and bright for a minute until that stopped as well. I thought all was fine and maybe that it was a fluke but as I pulled up to the gas station the car bogged out right at the pump. Thinking the fuel was low I refilled the tank and went to start the car to no avail. I then had a friend come down to give ma a jump and that didn't work either. I took the battery and alternator to advance auto to have them checked and both the battery and alternator passed, the battery once and the alternator 3 times. Now I notice a strange sound when I go to start up the vehicle almost like a squeal when the motor is turning over not a belt squeal but almost like something is rubbing that shouldn't be. I still need to fully charge the battery before I can give it a start but I am wondering if anyone has had a similar issue, especially with the squeal sound when the motor is trying to turn over?

I don't care what their tester says, that sounds suspiciously like the alternator to me. Especially since they are known for failing on this motor.

Well yes and no to the alternator. The BCM had to command the alternator to turn on. So for like 5 seconds after you start the car you're running on battery power until the alternator is told to start making electricity after the engine is running. I'd check the wiring to the alternator that none of it is frayed or coming apart. The squealing when you start the car may be that the BCM is always telling the alt to make power, therefore it would be under full load when the car starts. Understand the alt is spinning all the time but it has to receive voltage from the BCM for it to start generating electricity.

First I must ask with BCM stands for? But beyond that I am thinking that I am leaning toward the battery as I have the same rational toward how the alternator kicks on after the vehicle starts. But the thing is I can not seem to get enough juice out of this battery to get the motor to start! I checked to see if I am getting spark and I can smell the fuel getting dumped into the combustion chamber but I am not getting a full start out of it at all. It get like a half crank and then dulls out on me and I don't understand why. Its almost like the motor is seizing up but it gave no tell tale signs of a seize up at all before the initial dieing out as described in my first post on this thread. I think the issue with the alternator was a loose wire that I fixed when I put it back on but now I cant test my theory of that being the issue cause I cant get it to turn over. I just had the starter tested today out of pure curiosity and of course it was good as well. I guess just leave the battery to charge longer maybe?

Squealing = loose belt? Hows your serpentine belt and tensioner looking?

And FYI, the BCM doesn't control the alternator... the PCM does. BCM = body control module.. you don't even have one on a 95 (they didn't get put into the J-body cars until the 2000 model year).

Alright here is the update on my findings, slow progress I know but I have a busy life. I sprayed some starting fluid down into the intake manifold and kept cranking that puppy till it finally fired up. There is something loose inside the motor or maybe something out of whack but none the less its time to pull it and see what needs fixed! Its almost like whatever was lodged in there prevented the motor from turning over but when I sprayed the starting fluid in there it provided enough combustion to actually get things moving. So I will be removing the motor and replacing what needs replaced and if the price is right and the funds provide maybe some unnecessary power add ons. None the less project sunflower begins!
