I just finished putting ctr pistons in my ls and port matching the head. I put it all back together, it turns over has good spark, timing is correct. I am pretty sure the injectors are not firing, dont have a noid light. when I turn car to on and check the injector plug there is power there. I pulled out the plugs to see after trying to start and they don't smell like gas so thats why I assume that the injectors aren't firing. Its and obd0 motor with same ecu, injectors, and resistor box. I am wondering if anyone has some ideas for me to check. I have check tstat housing ground. fuel pump is running.
