Fitech with ZERO rpm on handheld - Won't deliver fuel

[DadofThree]

Yesterday I was trying to get my car running again, and am having trouble getting a rpm signal to the fitech.

My blue fitech wire is on the coil negative post, and I'm getting spark to the distributor. White fitech wire is getting voltage during start. I have a summit ready to run distributor with the summit recommended coil.
It will burn the prime shot, but I can see that no other gas is going into the barrels when turning the key.

Dave, my MSD dizzy has a tach output wire that feeds signal to my FiTech, maybe an option if yours has one

Good luck,

John

Seeing your other thread about the hot alternator brings a question to my mind. Is the battery fully charged? During cranking the voltage may be dropping too low for the ecu to function properly.

Facebook has a Fitech page that is chock full of info on the system and different issues with fixes. You may want to try that?

Battery is fully charged with charger hooked up while turning over.

Fitech FB Group says that they thinks that the ecu is dead. :(

After some testing with Fitech Technical Support, I'm sending it back in for ECU repair. I'm actually relieved because I've been pulling my hair trying to find the solution on my own. Hopefully, when I get it back I'll be ready for a gokart (silver lining). :)

Keep us up to date, I’m using a fitech unit and hope all goes well with it.

Hi Dave,

Sorry for your bad luck. It would be interesting to find out what caused the ECU to fail.
