Hey guys.

Been working on the truck, the coil pack that controls the passenger side spark plugs will come and go. It does not put out any spark, but once I start driving, it'll work, stop, work, stop... It's quite frustrating.

Checked the firing order, and it's correct. I've changed my plugs, plug wires, and the coil pack to see if any of those were the culprits...So far, no justice.

The plug that goes to the coil pack, I'm wondering if it's bad or has a break in the wiring that I should track down and repair.

Anything else I should check?

Thanks everyone!

What engine/year?

 

I'm dumb for not posting that to begin with.

2.3L 4-banger.
1994.

 

I can't remember if that truck has a lower part to the coil pack, when you took the coil pack off, the thing you unplugged it from. that may be bad.

 

Thanks for the suggestion. I'm working all day today, and have the next 2 days off. So I'm going to do some diagnostics. It goes through a harness, so I'm not sure where the next hop from the coil pack is. I planned on checking it out though.
