Will NOT start hot.

3) Attached timing light to number one plug wire, cranked engine, no strobe. When car does crank, the strobe flashes while cranking.

Huh?

Ordered the Pertronix Dist and Coil today. Hopefully this is the end.

Installed the Pertronix Dist and Coil, took all of 15 minutes. Truck fired right up after install, let it idle for 30min or so while I set the timing and cleaned up, shut it off, waited around 10 to allow for the heat soak, and it fired right up. Did this several more times after driving, let it sit and idle, shut it off, wait 5, then fire it up. So far no problems.

Just to be safe, I am going to relocate the elect pump to under the pass side seat, and wrap the fuel line in insulation. Hopefully after all of this I am good to go again.

After replacing plugs and wires, after adding an electric fuel pump, and adding a fuel return line, the hot starting problem in my case continued to deteriorate to the point where it would just die after idling for 15 minutes. So, at this point it became easier to diagnose. Spark check confirmed the coil was indeed dying as it heated up. I added in the ballast that came with the new coil on the assumption that the old Lucas coil being replaced had an internal ballast so it would probably do no harm. So far the truck is running better and there is no trouble with hot starts now. I still notice some hesitation going through the gears after a hot start, and idle is stumbling a little. I should have checked spark from the get go, but I was not wild about fumbling around under the hood in the middle of traffic, and I usually drive alone any way. A bonus is that the tachometer now works. I'm thinking the tachometer jumping around is a possible diagnostic tool if it is wired to the coil...
