1G No power to injectors

[EG Hatch]

Hi everyone. I picked up a mostly stock 1990 laser yesterday and it was running fine until I swapped in injectors and an ecmlink ecu.

I am measuring no power to the injectors, as well as none to pins 102 and 107. The battery backup and pin 63 both have constant 12V with ignition on. I tried swapping mpi relays and resistor packs for known working units, and I even put the stock ecu/injectors back in. Same problem. No burns in either ecu.

Help please as I am at a loss here.. I guess the CAS is next.

It was the CAS as I was able to hear the injectors all clicking when I plugged in a different unit. Sorry for the wasted thread.

It's never a waste bro. I've been dealing with this issue on my GST for a while and noone else has posted the cause in their forum. So here we are 5 years later and you may have saved my ass.
