After not being able to get it running on a stock chevy (ASDU) bin, and still not getting it to run with a howell bin I got from another member, I am looking for my problem.
If you have read my other posts, you may remember it will start and run, but just barely. It surges bad at idle, pops and backfires and dies after about 30-60 seconds, or if you touch the gas. If I unplug the bypass wire (like you would to set the timing) it will start and run (not the best, but semi smooth) it will stay there and run as long as I want, but if I rev it up any past 2000 rpm it spits and misses.
It seems to me there is something bad going on with the ignition. I have the base timing set to 10*, I have it set for that in the bin too. But with it running with the bypass unplugged, and not with it plugged up, makes me think I had a bad ignition module. The one I have I pulled out of a random truck at the junkyard. The truck looked pretty rough, but it was the only one I could find.
Looking at diffrent parts stores, these little buggers are expensive! Is there any way to test these things? I googled it without any luck. I dont want to drop the coin on a new one if its not the problem, but I dont want to buy a cheap one just to see if thats the problem, then be stuck with a cheap module. If it is the module, then I am gonna buy a quality replacement. But I dont want to drop $70 on a module if its not the problem.
I have the module on a nice heat sink with the proper paste between it and the sink. I have a ground wire run from one of the bolts to a good ground, I also used a multimeter to check the ground and make sure its good, and it was. Other than that I dont know what esle to check.
