Have crank but no start condition . Just replaced the
altenator and throttle body. Not getting an engine check
light at startup. I checked with multimeter all fuses and
replaced pcm relay. I do have power to the alternator but
am clueless as to how to trace back to the pcm.
Keep thinking its wire issue. Truck was fine until the repairs. Want to chase back voltage to the pcm. Then further if needed..
Found a bad connection at alternator pin. Replaed and check engine light is now on at startup. Still wont turn over. Pulled a coil and no spark. Checked voltage at maf and is 5v. Have a scanner and it is not reading any codes???
