Haven't checked for voltage yet. Does the ignition module signal to the ecm? then tell the injectors to fire in time? I will check for 12 volts at the injectors tonight hopefully. I was thinking I read on one of these threads where one of the guys had the same problem but I couldn't find the solution anywhere.

there should be a ride wire that runs to both injectors thats the power wire. one injector wire is dark blue the other dark green these are the trigger wires from the computer.
