can't get truck to start

[countrymoparguy]

So after fixing a leak from an o-ring on the back of the injection pump, truck won't start now. I pulled the pump, replaced o-ring and threw it back in. Primed the system, got fuel to the injectors. Cranks good, getting fuel but won't fire. Any suggestions as to what to check next? Thanks for the help. It's a 93 also.

Which oring did you fix? How much apart was the pump when you had it off?

Keyway not in the timing gear correctly is the first thing to check.
