Default HELP my fuel pump and injectors do not run on my FAST EZ-EFI

Hello

I run with Multi-Port Retro-Fit EZ-EFI kit on my 428 cobra jet
I have a problem, I have no negative to my fuel pump and my injectors, they will not start when ignition on.

There is power to my ECU and if I even made a negative contribution to the pump and injectors they will start.
I have RPM signal input on my handheld.

What could the problem be?

I hope you can help me

Regards
Jesper Pries

Default Sounds like you are missing a ground

Jasper I don't have a wiring master in front of me but there should be a relay to the fuel pump The neg wire should go to a frame ground. The same applies for the injectors. Need to see if there is a pos or neg controlled from the ECU. Most are now ground controlled and have a battery or charging power to the injectors. There should be a relay for this power usage too. e-mail FAST and they will walk you through this problem. Rick L.

If your pump won't pump, the injectors won't inject---------------------fix the pump-----

Most ecm control things by the negative or ground sides and Fast people over the years
(computer geeks,not mechanics)have used different terms to describe automotive electrical circuits--------
