Default intermittent spark loss-ignition module

having an issue with losing spark almost every other time i try to start my jeep. i have a 360 with stock dist, ignition system. replaced cap and rotor, do have 12v going to distributor. is this how ignition mods act when they are going bad? bad distributor? anybody else ever run into this? any help would be greatly appreciated. thanks

let me guess. everything painted to perfection? you are loosing grounds. you need to check all connections and add cleated washers under connection where they meet paint.

my pal had this happen on his mustang. wouldn't start due to paint.

Worth looking at i suppose. Should have mentioned the problem just began after 3 years of running perfect. Guess i will go ground hunting first, thanks Yetti

did some troubleshooting and its looking like the ignition module. should have known, i replaced one before. my question to all is can anyone recommend a good new unit that will be more reliable than the used one i bought? i tried a motorcraft unit from evil bay and it lasted about 1/2 mile, thats what made me buy a used oem and it lasted a year. dont wanna put any more used ones on. thinking about mounting two on inside fender since these are shit parts. thanks again for any info

Maybe I have just gotten lucky, but I have had great luck with Duralast from Autozone. I have a TFI upgrade on a 304, and my current ICM is easily 7 years old. THe only reason I replaced it 7 years ago is that I was doing the upgrade.

Stock ignition? Stock Coil? Coils will stop working when they get hot, if they are going bad. And, you should not have 12v going to that coil. There is a resistance wire that feeds about 8v IIRC.

coil checked fine. your right, not 12v, i goofed. it lit up my 12v tester, didnt get out the fluke. i think i have it narrowed down to module or pick up coil. if its the mod i think im going msd.

The aftermarket Stock replacement ignition modules have been know to cause issues in the past.

My 360 i skipped that crap and ended up going with a HEI Distributor Setup. Send it 12v and go
