87 240 DL was barely running, now won't turn over

Well, thanks for the suggestions brickboarders. I unplugged the AMM and tried starting up but it's just not happening. I'm just wondering, and forgive my ignorance, would a blown water pump bearing cause the car to run poorly at first and then to die like this? Since there originally was a whining noise coming from the water pump area perhaps this is all related. Also, I'm noticing a lot of exposed/cracked wires in different parts of my harness and another one coming off the ignition coil. Is it time for a new harness? This was a CA car that I brought with me back to Boston so this was it's first winter and it didn't seem to fair to well.

    Have you made sure that the alternator is putting out? "Was barely running and now won't turn over". One of two things,1) something else is causing it to run poorly and you simply ran the battery down cranking it over or 2) the brushes in the alternator have finally worn away and now it is running off of the battery, as the state of charge gets lower and lower in the battery the car runs worse and worse until it runs no more and of course will not crank over because the battery is dead. I would charge the battery back up, get it to crank over and run and then check you charging system output. You could even simply pull the voltage regulator out of the back of the alternator, two screws, and see if the brushes are worn away. If they are you will see that the inboard brush is worn away more than the outboard and the short one will not have that bright shiney surface on it an more. Just a thought.

      I'm sorry, what I meant was the engine turns over but won't start. There's a lot of gas fumes. It'll turn and turn and then almost catch but goes back to chugging. I don't want to burn out my starter, and it's pretty obvious that no amount of hoping is gonna start this thing now. The last time it started it ran like hell and sounded like it was running on two cylinders or something. It was rocking and shaking like it was going to bust off the mounts. What next?

        There's a lot of gas fumes
        "
        The fumes and "chugging" make me think "excessive fuel". The ignition is probably OK, because if it's totally NG, the fuel system won't operate.

        But I suspect that, by now your plugs are soaked and too wet to fire. I suggest you remove them and see. Clean them if possible, or put new ones in and try again, briefly to see if symptoms improve noticeably.

        If your battery is up to the task, you can clear out the cylinders by first pulling the 25 amp blade fuse near the coil, then cranking it (with plugs out) for a few seconds.

        Excessive fuel is most often due to a faulty ECT sensor (or wire), making the FI system act like it's about -40° and injecting too much fuel. Testing the ETC requires a DVM to measure the sensor's resistance and to verify the wire from sensor to ECU. If this is something you can do, post back for more info.
