Ok I have an 84 Prospector. Has been having starting issues for quite some time. Once started runs like a champ but sometimes I have to turn it over 4-5 times or more before it will get going. Talked to a big Dodge dude at the local parts store and he pointed me over to the ICM and it sounded legit so I swapped it out. After I replaced the ICM it fired up on it's first try. 30 min later after turning off to refill the tank no go. Took 4 tries, 2 laps around the truck cursing it out then a couple more before it would finally get going. Has a tested good battery, replaced all plugs, wires and distributor and the fuel pump was replaced a year ago in another trouble shooting event. The only thing I can say that I think may be an issue is it has seemed that if no other electronics are on, brakes are not on that it seems to fire easier. Am I missing something?
