So WTH decided to see if it would start up and it did!!! Woohoo it is fixed miraculously... Started putting everything back on to the cart (covers, air box, etc...) after finished it would not start! Checked for spark and none! Kept trying it and it would spark one time and that's it and it wasn't consistent either. Thoughts????

Is the plate that the ignitor and solenoid mounts to rusty looking ? I have removed many and cleaned to get a good ground. It is common on these carts

Trig123.... I have cleaned the plate and grounds, thought about running a wire from the negative battery to the plate... thoughts?

Can't hurt. Give it a go
While spinning it over with spark tester connected try wiggling the plug in connection that goes down to pulser coil. I have seen them not make good contact and cause your problem.
Did you ever test the pulser to make sure it is generating AC voltage ?
Unplug your pulser connection and stick the two leads of a DVOM on the two wires . Set your DVOM to the lowest AC scale on your meter. Spin it over. 1/2 volt is what it needs to fire.

The dude at the cart shop said the pulser coil is fine it had 1/2 volt. I tried a ground cable as mentioned and nothing changed. Strangely enough though, I checked for spark one time and it was firing! I actually got the engine started and running. I finished putting all the parts and pieces back on the cart and tried it again and nothing! Pulled the spark plugs and it would spark one time and that is it. Confused....

Hey. Did you ever figure it out? I had a similar issue on my brother's cart a while back. (96 txt) and it was this connection. (See pic). The male pins that push in had spread the female pins apart to far and were not making a constant connection. I was having the same spark experience you did and it kept starting and dieing. Then my old man was moving wires in that area while I was cranking it over and it started and died a bunch of times until we pin pointed the right connection. Hopefully this help you out or someone down the road.

Flushers- So I think I have found the problem... I took and cleaned the grounding areas (again) on the bracket where all the ignition components are mounted. Buffed the areas to the bare metal and made sure everything was tight when bolted back down. Another issue was the pulser coil was not putting out the right amount of voltage. Adjusted the air gap on it and it fired up after the before mentioned was done. These things are on a negative system so the grounding is important!!!

I was told about the pin issue you had as well, checked them and all were good.

If anyone has these problems of not firing, do yourself a favor and start with the grounds, it will save you a lot of anguish.
