gconcilio Posted August 1, 2011 Share Posted August 1, 2011 Does anyone know what I should read on the D2-9 terminal of the diagnostic connector on an 88 2.5L? I am trying to figure out why I have no spark. This terminal is on the output of the ECU "timing" output. I have no spark off of the coil, and no signal to the two pins on the coil. I am running out of ideas. Any help would be appreciated. All grounds have been checked, the CPS has been changed and is in spec. My next move is to buy and replace the ECU.
