'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.
TDC/#1 Cyl. on the compression stroke only. There are 2 TDC/#1'Cyl.'s. If you use the Exhaust stroke, your timing will be 180 degrees out. You won't like it. The symptom will be similar to a jumped timing chain. The Piston throw is slightly farther on the Compression stroke. http://fordfuelinjection.com/?p=71
It's a b*tch, finding out the hard way. A lot of people don't know the plugs fire twice, once on the compression stroke, & once on the exhaust stroke. Which is why they think it's trying to run if it's 180 degrees out!
If your referring to the TFI module, that doesn't require Dist. removal. The PIP sensor does! (aka: Stator/Hall effect) The PIP & TFI module are usually replaced at the same time, because of their close interaction, and similar usable life expectancies. Kinda like a preemptive measure. http://fordfuelinjection.com/?p=25
