ECU/ Check Engine Light

[jbchase]

Hey, any one have a clue on my Check engine light is flashing on and off. When I hook the Datalogger up I can connect to the ECU but can't see any engine code and none of the sensors are reporting back to the ECU.

Thanks

Does your datalogger work?
Have you tried reading the codes the old fashion way with a multimeter?
