Erratic Idle, Backfiring (Page 3/6)

I checked the coil. It was reading more or less correct resistance in the terminals. I also replaced the spark plugs since I thought that might be it.
I'm really running out of options here. Nothing seems to be working. Nothing at all.

Its now doing this thing where if I let it sit for a while, it'll start up and then immediately die again. The amount of time it stays alive is shorter and shorter until after about 3-4 times, it won't start at all.

EDIT: I also pulled off the fuel filter and checked that. Clean fuel from both ends, no issues there.

This video here pretty much showcases the same behavior: https://www.youtube.com/watch?v=iGGUQVyGAIw

Re-reading this thread I see no reference to the Ignition Control Module. A common issue if the car dies randomly.

Replaced the ICM. No dice.

I'm heavily considering throwing in the towel and getting rid of the vehicle. At this point I don't think it will ever run again and if it will, I doubt I will have the money to get there.

More information:

Yesterday when I was pulling spark plugs, we tested the spark plug wires too. One of them might be dead and another had higher resistance too. Both were on the same side. I don't know if this would cause the engine to die after starting.

When I was replacing the ICM, I checked the pickup coil resistance and that was perfectly fine.

The fuel pump primes and runs too.

There are some vacuum lines around the MAP. Make sure one has not been disconnected accidentally. Or. unplug the electrical connector on the MAP and see if it runs.

All the local vacuum lines are intact. Unplugging the MAP sensor didn't change anything.

Do you have a spare ECM?
Addition1291 AUG 25, 05:43 PM
Unfortunately, I do not.

Ok. So on a whim I decided to check the distributor cap again. Take a look at these connection points on the inside.



This could very easily be my problem. Thoughts?
