    I tried what u said I found something very interesting. As soon as I hooked it up everything came on like I turned the key to "on"

    Still won't start with the jumper wire. Gonna try and warranty the distributor. They won't just swap out icm they want the whole distributor.

    It was backfeeding to the keyed side of the switch once the jumper was hooked up. If you disconnect the power feed to the resistor from the ignition it wont do that, but no harm done. If you don't have one of these, get one. https://www.amazon.com/Lisle-20610-I...e+spark+tester
    Fastest way to check for a no spark or weak spark. Checking in open air is not the same as checking in a cylinder with compressed air and fuel. The amount of power needed to spark under those conditions is far greater. At 12 bucks you can't afford to not have one!
    I think warrantying it is not a bad idea. Electronics generally fail fairly quickly, or last a long time. Just like a rebuilt engine, or a machine tool. My number one rule of diagnosing is always suspect the new parts. I've been burned too many times assuming because something is newer it is still good.

    Got my spark tester in. And nothing. While cranking no spark at all. When u turn the key on I get a faint spark and the same when I turn the key of none while cranking.

    It sounds to me like a bad icm again. I would warranty that distributor. The wiring should look like this little sketch. Make sure your icm isnt hooked up to the 6volt side of the ballast resistor. That would probably burn it up

    yes it would - dc circuits with low voltage draw more current to make up the shortfall, which cooks things...

    I've got one on my truck. I recently removed the back braces tho. They took up too much bed space. I've got my lights mounted on the other part.

    2nd distributor is back in and running. Test drive went good. Drove it to work this morning and as I was in the McDonalds drive thru the temp gauge started climbing. A/C was on and they were running slow as normal so I'll be monitoring that now.

    Glad to hear she is up and running again! Check your fan clutch. With the engine hot if you shut the truck off and then try and spin the fan it shouldn't go more than 1 revolution. Thats the rule of thumb I know, but someone more familiar with these trucks may have a different amount of rotation.
    I run a rigid mounted dirt track fan that required drilling out and retapping the water pump flange. Cools the truck awesome, but the water pump isn't made for that much thrust load. I got about 30 or 35k miles out of the first water pump it was mounted on
