distributorguy Posted April 19, 2019 Report Share Posted April 19, 2019 Your new plug wires are junk, or you didn't pull the boot back and fully insert the wire into the coil. Plug wires should be under 1000 Ohms per foot. A lot of new ones can range from 2500-5000+ Ohms per foot - junk. New NGK and a lot of the "build your own" wires use good low resistance wire. The only way to know is to test them with an Ohmmeter on the highest setting. 500 Ohms shows up as .5. 1 Quote Link to comment

If what you're saying about pulling back the boot is true, would it still run under dry conditions? 1 Quote Link to comment
distributorguy Posted April 19, 2019 Report Share Posted April 19, 2019 Yep, but you'd be stressing the coil. Test your wires. NGK used to make them with over 7000 Ohms on the shortest wire. If you got some that have been sitting on the shelf a while, you found the culprit. 1 Quote Link to comment
Stoffregen Motorsports Posted April 19, 2019 Report Share Posted April 19, 2019 I found this out the hard way last summer while on a trip to the Rubicon. My coil had a crack in the nose, where the coil wire was inserted. During a very deep water crossing (halfway up the radiator), the water got in the coil and almost drowned me out. 1 Quote Link to comment
banzai510(hainz) Posted April 20, 2019 Report Share Posted April 20, 2019 (edited) put the old stuff back in. Try that first. Coils most never go bad!!! Weird not running in rain? condensation under the distributor cap?????? Previous owner of my truck said the gas gauge would rise when wet/ rain out. Find out fuel neck and tube was looseenough to let water run in the tube and tank. filling with water and rusting out and getting rust in idle jet Love NGK wire sets insert and feel the click of it going on tip of plug Edited April 20, 2019 by banzai510(hainz) 1 Quote Link to comment
Thegreek Posted April 23, 2019 Author Report Share Posted April 23, 2019 Ok...so I pulled the boot wire closer to the coil which made it nice and air tight, and put dielectric grease on everything spark plug wire related including coil.....and put the old coil back on......drove it 3 hours in downpours......FIXED!!!!! THANK YOU! 3 Quote Link to comment
