to check the pump have someone stick there head under it u should hear a hum while cycling the key on n off or just put a few dops of gas down the throttle body c if it starts if no go but if it does run occasionally tery the crank sencor on the bell housing

I can't think of a single fuel injected rig that has a choke :roll:

I'm pretty sure ive seen TBI with choke plates before. i could be wrong

No Fuel Injected vehicle has a choke. A Choke is for a Carburetor.

Back to basics. In order for an infernal combustion engine to run, it needs fuel, air, and spark. If it cranks we'll assume the valves work and it gets air. The fuel pump is making noises, so for the moment we'll assume that it's putting out sufficient pressure and volume to at least start the engine at idle speed.

 

I have not seen any mention of checking to verify that there is spark. Check that. No spark could be caused by a bad CPS (crankshaft position sensor), or -- more rarely -- a bad coil or bad ignition module.
