Your diagnosis is correct. The check valve in the fuel pump is letting the gas drain out of the line from the injector rail, and cranking for a long time then starting is indicative of this. Replace the fuel pump.

SOURCE: outlander 2003 timing belt broke?

its not broken yet but its stretched which is why it backfires like it does....if it were broken all it would do is spin and nothing more

SOURCE: car starts run good for a little while then dies. On the road car acts like it is running out of gas.

Do you have gas pressure at the fuel line going into the injector? If not, do you have gas pressure at the fuel filter at the gas filter by the passenger real wheel? If not, do you hear the fuel pump kicking on when you turn the key? If you don't have high pressure (spray) at the rear filter, but you hear the pump, then you need to drop the tank and change the filter sock at the pump, which is a pain ;-( If you don't hear the pump, then check the relay controlling that.

Sounds like you have carbon buildup in the exhaust system. Check your vacuum pressure. High pressure reading means exhaust problem.

You need to have your exhaust system checked. Backpressure can cause serious engine damage if not corrected in time.
