Testing ecu?

[seven.62]

i am wondering if there is anyway to test to see if an ecu is good or not. I am having problems with my wiring and i think i might have fried my ecu. I can put it in another car because no one locally has a s14sr. so is there anyway to test it with a multi meter? it hasn't smelled like smoke or anything but i would still like to test it.

key on you should have the CEL, if not, startd digging deeper to supply power etc. You can also check to see if the ecu makes ground on the injector wiring while cranking.

well part of the problem is the wiring harness, so i wasnt getting dash lights, injector signal to begin with, so other than plugging it in there isnt a way to test it?
