Hello, first time on the boards.

so what do i have..

its a 1986 Iroc (5.0L 4bbl).

the problem i have is no spark to the plugs. My question is, how can i check the ignition module? i have replaced the dist-cap rotar and the internal coil ( not that expensive), pickup coil seems ok. The wires appear to checkout. then i got down to the module, is there anyway to check this or is it just replace it and hope that was the cause. About how much is the module? Is there anything else i should be testing?


The problem all happened when the car had been sitting for a looong time, battery went dead.. jump started it ran for while, battery was completely dead. So had to jump it again.. but for some reason it didn't jump start this time. Ended up buying new battery, and now i have no spark.

Thanks

1986 5.0L 4bbl, 5spd, all stock

There is a thick wiring harness to the pass side of the distributor. There should be an open female connector in there that you can connect a test light to.
The wire might be green, I don't remember, but it's the only open plug there.

This is the coil triggering wire. Test from there to a good ground.
Crank the engine and see if the light blinks. Make sure you plug in all the distributor leads.
Check the coil and coil wire. I've seen the coil high tension wire boot go bad where it plugs into the coil top.

any auto zone can check your module an you can get a hi-po one for about $25. i am asuming this is a computer controlled 4bl, if so the ignition is also computer contrloled check codes.
