Fuel pump is good, changed out throttle position sensor, changed spark plugs, checked for spark while cranking and it's good. Anyone have any ideas for something else I could check or replace?

. Check for codes.

. Check/replace the Crankshaft Position Sensor.

. Check/replace the Ignition Control Module (ICM).

How did you determine the fuel pump was good?
Did you test for fuel pressure? You also need injector pulse (that's a little trickier to test).
