I am stumped on this, my ecm isnt grounding out the Injectors so my car won't run. the fuel pump is good, fuel filter, injectors (if I ground them out myself they work good. also the check engine light won't come on. I've tried a different ecm from a buddy and it still didn't work. I checked all the grounds, they have about 1.3 ohm resistance. Plus the ecm is getting plenty of power. I was wondering what else I could check for? any help is appreciated
