Been a while since i posted anything, but my 6.9 has been stored up for a while, decided to take it out for a run it drove well for about 5 miles and limped home the rest of the way, after got home would not start, cranks over but will not fire, i put a different distributor in thinking this might be the issue, but i failed to mark the old dist. just totally slipped my mind, so what is the proper procedure in setting timing for a new dist, i am starting all over again, in other words pulling dist out and re installing, help please!!!!!!!

eating breakfast and typing without any reference material, but the simplest set of steps would be...

hand crank to TDC on piston 1 where both cam lobes point away from the head (both valves closed). Watch the direction the rotor's moving as you crank it.

Put the distributor in so that the rotor's leading edge is at the #1 mark on the distributor. (Check that the mark has your #1 wire).

At starter speed (about 200rpm), you can time the motor to something like 0 and get it to start if that was the problem.

For next time, use a timing light before pulling the distributor. It can quickly tell you if the ignition system is providing a steady pulse chain.

first thing to think about is a bad ground. The factory ignition module is not just a giant heat sink, those three screws that hold it to the body ground it as well. The various screw connections to the resistors can be loose or corroded too.
