So I was driving last night, 15MPH engine sputtered and died, quickly but not catastrophic sounding (in fact no sound at all).
Presuming operator error (even the best of us stall sometimes?) I immediately went to restart the vehicle. Starter cranks (weakly, seemed as if there was resistance at the flywheel) then stops. Sounds like its engaging but just simply cannot turn as if there is internal resistance.
Well I am in the middle of the street, presuming the starter has failed I decide to roll start the truck (I had just started in 3 mins ago) and I am on a slight downhill. I let the truck roll, popped the clutch, nothing, doesn't seem to crank.
So I parked it, left it, went back today to do some quick diagnostics:
-Pulled the valve cover, pulled the rocker arm
So:
Questions:
Could a failed timing belt cause a failure that would lead to the resistance at the flywheel?
My current plan of attack is to drop the oil pan and inspect the crankshaft
Pull the timing cover and check the belt
Anyone have a similar experience that could share it this way?

-Pulled the valve cover, pulled the rocker arm
All pushrods are straight, all rockers intact, engine turns over by hand
-Used a jump pack with the rocker arm removedSeems to revolve maybe once or twice, extremely slow, then stops up again
I noted that without open valves the compression may cause difficulty in revolutions
Basically behaves the same way as it did with the rocker arm attached
-ruled out fuel issues (new lift pump, again it seems like there is resistance on the flywheel)So:
- Stalled while running
- wouldn't restart with a 'pop start'
- Seems to be resistance on the flywheel vs a starter issue (also a starter would not have caused the rolling failure)
- All pushrods intact, all valves look good (new turner head less than 6K miles ago)

I just replaced it but it doesn't mean it didn't shred somehow
