still chasing gremlins!!!!!! 5.0 no spark!!!!
I finally got a chance to get back to the truck, with the haynes manual in tow this time in order to chase things in thier order of priority. in the process of going through what i had before, i found a couple of changes. First, when checking for test light flicker at the tach/ground terminal of the coil, the light is bright, but no flicker this time. it checked out ok for continuity between the terminal and the #2 slot on the control module. i went through all the other checks and everything checks out ok(voltages,resistances, grounds,etc.) the other thing that changed, is that fuel pressure at the schrader valve with key on, is now 95 LBS, not the 40 i had before.i also ran another koeo self test and came up with 121 and 123 codes. i just can't figure this thing out!!!
