I've got a 22R in an 85 truck that won't start. I believe the cause to be no spark because when I spray either into the carb it won't fire up. The signal generator is showing 156 ohms which looks to be within specs. The primary resistance on the igniter is .6 ohms. My Haynes book says that should be .4 to .5. The secondary resistance is 8.96K ohms and is within the specs of 8.5 to 11.5K ohms. Could the .1 over of resistance of the primary mean the igniter is bad?

This engine was running fine until I degunked it... I checked the dizzy and all electrical connectors for moisture and they all look fine.

Thanks

Gary

Only real info i have came across about ignitors. The one in my 83 went south a while back and i stumbled onto this a few months a go and saved it for the next time.

Good Luck

 

Thanks for link, I may try go this route!

 

Stupid question; you're not getting any spark at all? is it at least getting to the distributor?

 

On your question about 0.1ohms over... its ok. Within measurement accuracy of your DVM.

 

I was getting spark from the coil to #1 cylinder, but not to the rest. I replaced the plugs and wires and she runs fine now. Never heard of wires going bad overnight like this. Weird.
