JEEP GRAND CHEROKEE BACKFIRE PROBLEM

1996 Jeep Grand Cherokee • 126,000 miles

My jeep backfires through the intake. I have cleaned the fuel rail, replaced fuel filter, distributor and wires seem ok. Replaced ignition coil. Ran injector cleaner through. The o rings look ok. Will replace the fuel pump if I can use one off a '97 ZJ V8 to my '96 ZJ I6?

Check the ignition timing.
