Take the cap and adapter off the top of the distributor.
Turn the engine by hand (crankshaft bolt) until the pointer in the distributor points to the rear about where number one wire was on the cap.
Then look at the pointer down at the crankshaft damper an position the engine where the pointer points to Top Dead Center (TDC).
Do not move the engine until after the new distributor is in place.
Remove the hold down bolt and pull the distributor out.
Drop the new distributor in and have pointer pointing to where number one wire would be on the cap.
Start the distributor hold down bolt until you can just turn the distributor by hand.
Remove the SPOUT shorting bar.
Hook a timing light to number one wire after you put the rotor, cap and adapter back on.
Start the engine and turn the distributor until the pointer points to 10 degrees BTDC.
Tight the hold down bolt and recheck the timing.
If still at 10 BTDC put the SPOUT back in and check to see that the timing moves some.
If so remove the light and you are done.

You should have a non-roller flat cam so it would be a cast gear.
Steel gear is for roller cams.

The smaller portion of the gear will have a rough cast texture for the cast gear and the steel gear will have a smooth machined surface.

I hope you pulled the SPOUT out when you timed it.

Sound like the fuel pump relay is bad or the computer has a short to ground on pin 22.

The fuel pump relay is on the drivers fender apron:


Pull the EEC power relay out of its socket and the fuel pumps should stop.
If they do not you have a bad fuel pump relay.
If they do you may have a bad EEC power relay also but your fuel pump relay may still be bad too.
Lets not talk about the computer yet.

Great thread guys, and just the info I was looking for. I don't have my manual yet and have to change the distributor on my '96 F-250 XL with a 4.9L 6 cylinder. Does anyone know the timing I need to set for in my case? Thanks in advance.

John
