'91 5.0L distributor/timing problem?
The distributor mounted icm shorted out. So I got a new one, but I forgot to mark the rotor alignment on the distributor housing. I did mark the distributor position in reference to the engine. So what should I do now to get it running? It almost starting when I put it back together but I'm assuming the timing is off now. Thanks for any help.

thanks. yes I do have a haynes. I'm just not much of a mechanic and everything is new to me. what's the best way to turn the crankshaft manually. do i have to use a breaker bar on the pulley bolt as mentioned in the repair manual?
Just to clarify a couple of things. Your distributor has a TFI module, that attaches to the outside of it (unless remotely mounted). Neither type, require Dist. removal for replacement. Your Dist. also has a PIP sensor (AKA: Stator, hall effect) which does require Dist. removal to replace. It's normal practice to replace both (TFI & PIP) at the same time because of their close interaction & similar life expectancies. So, as for determining TDC/#1cyl., 1 complete cycle is 720 degrees. TDC/#1 occurs twice. Once on the compression stroke & once on the exhaust stroke. You want to work off the Compression stroke! Exhaust stroke TDC/#1 puts your timing 180 degrees out. Piston throw is slightly higher/farther on the compression stroke. Haven't had to do this for a long time, but I believe that's the drill! If you want to see some really crazy stuff, 180 degrees out will provide it! http://fordfuelinjection.com/?p=71
