Good evening, is it still necessary to make the resistance test from the ECM and harness connector? Is this also the correct way to check is there is a signal pulse from let's say the crank sensor or the ignition coil connector to the computer? I am thinking I do not have spark at the coils due to having a weak signal because I have power and ground. Thank you.
