    The TunerPro download page does not have an .adx file for our ECM... We have the $99 / xxx6299 ECM http://www.tunerpro.net/downloadBinDefs.htm#GM Ugh

    ALDL cable arrived and connected to laptop okay. Which OBD1 scanning/collection software do you recommend?

    Thanks! You guys are amazing! A real perfect storm of mechanic's errors, here. A little embarrassing, actually! ;-)

    Not sure! I asked myself the same question! We live in Maine right near the ocean... Lot's of fog recently and truck has been sitting halfway in our barn door with hood open... Salt air must have got to them. It certainly eats everything else here!

    Will do. Got her running with new plugs... Pic attached of totally fouled plugs with only 100 miles of testing and then cranking after IM gasket job. Wow!! Thanks!!

    They were new right before the intake manifold gasket job... literally 100 miles in them... had double checked gap a week ago and reported condition in my post... checking them all for spark quality and will clean them when I finish this post!

    See my response about checking rotor movement? It seems like it is connected and has "minimal" play... I have no idea what the accepted "slop" in the system is but there is not much in this one.

    Would a new one that came with a new distributor go bad right away?!?!

    Following your logic and suggestions, here, I pulled the distributor cap and rocked on the nut holding the harmonic balancer. Interestingly, I could turn it clockwise (normal motor direction) and distributor responded immediately. However, the nut came loose when I tried to rock it counter-clock...

    with the plugs all looking a little different, I'm sure the age of the motor would indicate that there are some inconsistencies with valve seats etc. I have not done a compression test as someone walked off with our compression tester. Again, except for the conditions of intake manifold...

    '92 K2500 5.7 TBI - Crank for days and no start after intake gaskets...

    Thanks! No. Only did intake manifold gaskets at this time. Did not go deeper into motor as no other symptoms were present. Timing light is dead on the mark and does not jump around at all... Ran great right up until the problems described here, before the gasket job. Thoughts??

    Thanks! Yes! Marked wires and cap before taking it out... Dummy proof!

    '92 K2500 5.7 TBI - Crank for days and no start after intake gaskets...

    THANK YOU! Great suggestion. Will do. Plugs were replaced as part of the process a few months ago and definitely look darker/wetter than "normal for low miles on them. NOTE: Old plugs had about 12K miles on them and were mostly tan/brown and a just little "burnt" at the electrode tip when we...

    Grateful to have found this Forum!

    I ran a '69 Pontiac with a 350 "back in the day"... Learned most of what I know about old school wrenching from that car and the few that followed her. Recently got into vintage GMC truck world with my teenage son... We bought a "barn find" '92 K2500 and have been having fun with the basics -...
