87 4.0 lives again!

I can't believe what I've been through for just over four weeks with this truck refusing to fire and I'm shocked at what finally got it to run again.

 

I finally had a helper to crank the starter from the switch while I jiggled the connectors on the ignition control module and got a quick burst of fire with the engine threatening to start even though it didn't fire up. My helper had to leave so I took the newer ICU off and tried to modify the female tubes to be tighter which ended up being almost not at all. I put it back on and still nothing! I was at my usual complete loss. The ICU was only purchased a couple of months ago and it did work for the first month even though I would have this firing issue after warm ups. The new Napa CPS and grounding cables were good upgrades through all of this as was removing the C101 connector. 

 

Anyway, I got thinking about the 29 year old ICU and dug it out of my scrap pile, cleaned it up with a wire wheel and put it back in place of the new one and guess what? The damn thing has started every stinking time since! I can't believe it. Today is day 3 and I made two trips to town with it starting perfectly every stop I had to make and not even a hint of the firing problem again.

 

I've since lost my receipt for the new ICU so I'm eating it and I bought it at an Advance auto parts store, who I usually trust for decent quality parts. I will be buying any other parts like this from Napa now after reading Cruiser54's appreciation for them from a professional viewpoint. Am I allowed to plug for Napa here? I just did anyway. 

 

I am so thankful that the old girl is up and running again! I'm half way worried about the 29 year old part that "solved" my problem but so be it. For now, I'm not afraid to take it out and go where I need to. If the problem ever starts again, I'll know to trust the next ICU from Napa. 

 

Thank you all for putting up with my crybaby baloney and Cruiser54 for his understanding of Renix ignitions!

Advance should have you in the computer by name or phone number for a a year worth a try.
