My guess is the stress may have taken out the lift pump then. Disconnect the output line from the lift pump. Thats the part the finger pump primer is mounted on and see if fuel squirts out when cranking the engine. When you report what you find with this test others can suggest things.
If nothing is coming out of the lift pump take the input line to it and submerge in a container of fuel. See if pump does or does not pump it.
Another thought was maybe a fuel filters contents where agitated by the unusual increased fuel volume. Might have plugged up. So if lift pump produces flow I might consider them. The worse senario of the timing chain going is not an issue at least. That is great.

Now if the lift pump will not pump fuel with you supplying it with a container of fuel do not leap to the conclusion it is the lift pump. It probably is at that point yet another test has to be done to make sure the lift pump activation system is still there.
