Engine Performance problem
1986 Oldsmobile Firenza 4 cyl Two Wheel Drive Automatic
Ok so I was sitting at a red light. All of a sudden my car cuts off. It didn't sputter, or stall, it just cut off. Still had power, but the engine wasn't running. So I pushed it into a parking lot. In the parking lot, and over 3 days, we changed the alternator, ignition module, distributor cap, spark plus, and ignition coil wire. Still couldn't get it to start. So we had it toed.
We got it where we wanted it and started working on it again. After we got it stable we tried spraying starter fluid into the carb, pouring gas in it. Nothing is working. The whole time we've had to keep jumper cables connected because the battery will go dead from trying to start it over and over.
I think maybe the timing chain could be off, but I don't know. And if that is it I don't know how to get to it.
Any suggestions on what could be going on and what to do about it? Thanks!
