Okay, going by what you described, are you sure that you have the timing marks lined up? Second, did you check for spark? I have now clue of the miles or anything else, but if it just stopped running, it's probably the ignition module located under the distributor cap.

Well it sounds like your in the throw money at it mode so try the fuel pump next.

Fire, fuel or compression! More info needed!

What model and year if its stock? If its not stock what is the fuel system and ignition system? Was there a major issue with the timing chain? By the time a chain is bad enough to cause a major running issue the rest of the engine is going to be pretty worn out too. Its really rare to have a chain break so that too would point to a zillion miles and a work out engine.

Possible ignition module inside the distributor is bad.What year truck is it? Possible ruptured fuel line just above the fuel pump just inside the tank. Plugged fuel filter under and on the frame. Lose battery connections.

Do you have power at the Distributor on the red wire when the key is on and in the start position too? Are you aligned right on the timing chain and distributor? Did you check the coil? Does the engine get spark? Have you checked the camshaft or crankshaft position sensors if it has them? Did you check the oxygen sensors if it has them? Does the engine get fuel? Does the engine have the right amount of fuel pressure? too many possibilities. Check some of this and get back here for more help.
