It happend when I changed my headgasket about a year and a half ago. It was working b4 I swapped the headgasket so idk wat tha problem is! Is there a fuse that's hidden that I should check? I tested everything from the ecu output to switching switching ecu cluster and distributor. I was thinking about just running a straight wire to the cluster from the ecu. Would that work?

 

check the blue wire coming from dizzy.

 

What would I check 4? Voltage?

 

That or make sure you didn't snag the wire when you changed the headgasket.
