80 258 ignition ques

[johnnyreb]

So I have a ignition ques. I have an 80 CJ5 with AMC 258 i6 / 4.2l . Does it hace an ECM or just the motorcraft ignition module? I hate the mess of wire running to and from the dist. I have even considered instaling a points dist upgraded to a pointless module to reduce it to one wire. That idea also has appeal for me as I can keep a spareset of points for back ups. I like simplicity.

Post a pick of the left and right side of the engine so we can see how it's set up.

If your dissy as points I don't think you have a ECM. If it does it will have O2 sensor.

 

[johnnyreb]

it doesn't have points. it has the brain box on the wheel well. where would the ecm be located and what year did it start? i don't see a o2 sensor

Shouldn't have an ECM.

Only electronic ignition.

Do yourself a favor, get a one wire DUI.

Interesting rig.

I'll look into the DUI.
I presume you are referring to my avatar pic?That's dad's racing jeep from the 70's.

Yours wont have the "computer". That didnt come about untill '83 and it would be located behind the dash right around the glove compartment.

Thanks petescj. That'll cross nutter bypass off my list. I thinking maybe using some of teamrush's upgrades too. Since it technically dad's jeep (says it's ours), GM parts are most likely out, he doesn't care for them.

The Team Rush is a great upgrade for the AMC 258 i6 / 4.2l I highly recommend it.

I have read the teamrush write up. although the msd box maybe a little out of the budget right now. So maybe cap wires and coil right now. Plugs are new, so regap plugs is free.
