take the brown solenoid wire off of the starter relay to(termporarily)disable the starter & see if you have fire to the coil positive primary terminal and to "point" of the ECU pentastar connector when you turn the key to start(ign2). Take off all wires from the coil negative primary terminal & w a jumper w alligator clips jump from there to ground repeatedly like morse code & w key on see if the large coil to dist secondary wire held 1/4" from ground is sparking. How far are you from Parsons, my home town?

When you repeatedly grounded the coil neg terminal like morse code you had to hold the coil secondary wire VERY close to ground to even get a spark, correct? Jump 12V from the batt positive to the upstream side of the ballast & see what you get for spark(key on) then repeat w 12V to the other side of the ballast & if you then have a better(blue) spark see if it will start & if not jump 12V to the point of the pentastar plus(the above) to the ballast & see if it will start.

Everything hooked back up with the test light on the coil neg primary terminal(& to ground), it's lit in "on" and in "start" & does it blink on & off when you crank it

Hey you're quite welcome. alright, this means the ECU is not grounding the coil primary circuit like it should. check that it (the ECU base) is grounded good

We've just about got it, an "open" somewhere. double check the connections and the plug ins(& the ECU base)
