Super Jet No start

[JHD]

Installed ADA head. Checked compression. Primer wouldn't get fuel to carbs and turned over multiple times trying to start. Dumped a little fuel in the carb. Started, ran for 5 sec, died and now I get nothing. Battery is good. Replaced s/s switch last spring and appears to be good. Where do I start?

Well its fuel starvation, so did you cross fuel lines up, or is tank seal missing, or dodgy one way valve. Fuel tap not turned off ?

Not fuel. Once it started it sucked fuel through the lines. Primer now pumps fuel to carbs. Start button does nothing. Electrical problem. Nothing happens when I push the start button. Nothing.... Fuse in the E box is good. I did disconnect and tape off the heat sensor but it started after that.

I had this exact same thing happen to me earlier today, I disconnected the battery, reconnected it and it started up immediately, it's worth a try.

Disconnected battery. Engine turned. Put s/s switch back together. Nothing. Disconnected battery again and again I get nothing.

if you dont hear the relay clicking. its most likely either a bad start switch or bad ground from batt. really just gotta chase it down with a test light or meter. not really gonna get an answer here. id start by opening ebox and checking for 12v at battery side of starter relay.... if u have 12v there then ur start switch prolly isnt sending 12v back to relay. try jumping the 2 prongs on the relay

Disconnect the clear start stop plug.

Verify you have 12 v on the red wire.

Jump red to brown on the E box side of plug.

If it turns over, issue is in start stop switch. If it still does nothing, issue is in e box.

Check all cables. They go bad. Trust me. And it can be intermittent. It almost always is when they do.

Thanks guys. I'll dive into it this week and let you know what I come up with.

Yami S/S switches are known to fail.
