I have converted my 2.8 to a duraspark dist and HEI module. It has been running great for the past 2 years or so. I drive it daily to work and coming home the other day it just shut off like you turned the key off as I was cruising down the road at about 60 mph. I pulled over, it would not fire at all. Got it towed to my house and the first thing I did before I went inside was to spray some starting fluid in the carb. No help. I had been pumping the throttle linkage to see if there was fuel squirting. So apparently my module went out since adding fuel didn't help.
Next day I installed a new HEI module. Cranked it over, it sounded like it wanted to run, but would not take off. I figured I had drowned the sparkplugs. I pulled them and they were pretty wet with fuel. Ordered some plugs, but won't be able to get them till tomorrow. So I took the old plugs out, they were very wet. So I took brake clean and cleaned them off and dried them out, and re-installed them. Would not start. I put a little starting fluid in it again, would not start. Not even trying to fire.
I checked for spark, getting spark. I know I have fuel. It was cranking very evenly, but I though I should check compression. Easiest cylinder to check was #4, so I put the compression checker in there, cranked it over and the checker shot way up. But it also tried to start? So I cranked it again and it fired right up on 5 cylinders. Sounded ok, so I let it warm up a little bit.
Shut it off, took the checker out, put the plug back in and hooked the wire on it, then got in and tried to start it. Would not fire at all! I said to myself what are the odds? So I unplugged the wire on cylinder #4, and it cranked right up. Weird? So then I went to plug the wire back on #4 while it was running. Besides getting zapped, it went back on, smoothed out on all 6 cylinders and was it's old self.
Got it off the trailer and back up to put it inside the garage. As I was maneuvering into the garage it stalled on me. I went to crank it back up, nothing, just turns over. I go out and unplug #4, crank it over and it fires right up. I thought I may be jostling some wiring when I messed with the sparkplug wire, so I messed with all the wires while it was running, no change.
Got it into the garage, I think I have some sort of problem with my high voltage system. I am going to put the new plugs in tomorrow and try it. If that doesn't work I am going to take a peek under the dist cap and see what that looks like, and check all the sparkplug wires. Never had something like this happen before.
