Distributor not turning
I just purchased a 94 e150 with an inline 6. I have no experience with this engine at all.
I purchased it with the PO saying it was a no start because of the computer.
so I checked for spark, No spark. I then replaced the ign. module and coil, still no spark.
Then like a shmuck, I checked what I should have checked first, the distributor. crank, no spin.
Usually I would instantly blame a timing chain, but I hear this only has gears, no chain.
What is the likelihood that this is a broken gear?
Possibly the rotor gear pin?
also if anyone has an exploded view of this engine so I can get a visual, I would much appreciate it.
thanks

It could be a sheared pin in the distributor gear or the cam gears could be stripped or missing a few teeth... The cam gear is a nylon coumpund type gear and the teeth can strip..
I suggest you pull the Dizzy, Check the shear pin in it and try to visually see if the cam is rotating..

I just bought an '81 and have the same problem. When I try to turn the rotor by hand it wont turn that way either. Does this mean its the cam gear? I'm an old Pontiac v-8 guy so I have no idea how the distibutor down low on the side of the motor is driven by the cam gear. Did anyone have an exploded view of the motor. The Haynes manual I bought doesnt discuss how the distributor is driven anywhere I can find. Thanks, Tommy

Tikler-- the distributor is driven from a gear that is part of the cam shaft. The dist shaft has a gear pined to it and also drives the oil pump. You may have a bad timing gear. Pull the valve cover and see if the valves move when the engine is turned by---- HAND---, don't try to use the starter as I am not sure the valves clear the pistons at TDC if one of them is open due to a stripped timing gear. You won't have to move the crank far to tell if the valves move.

Thanks stractor. I'll give that a shot. I always wanted one of these trucks and I'm determined to get this one running again.

Ok. Thanks for everyones help. All info led to pulling the timing cover and sure enough, plastic cam gear with 10-14 missing teeth. I have bought a gasket set and a set of steel gears. The crank gear has screw holes for a gear puller but I dont see how the cam gear is supposed to be pulled without damaging the cam. Also, what holds the thing on? There is no bolt. I'm fairly sure this is a stock setup so I guess it's pressed on? Any tips on this procedure would be greatly appreciated. Thanks, Tommy

I would still pull the distributer out and check the teeth on the gears to make sure they are ok. I replaced my timing gears after they exploded and then two months later the distributer gear blew up. I replaced that and then the gear on the cam broke and had to replace the timing gears, cam, oil pump and the distributer. Things like that really p!ss people off. It is really worthwhile to check.
