Chevrolet Repair: No Power to Fuel Pump, oil pressure switch, chevy express 3500

Question
I have a 2002 Chevy Express 3500 with a 5.7L engine and it will not start.  The fuel pump does not run.  I got no power to fuel pump connector at harness that plugs into fuel pump. checked relay, fuse. all ok. relay clicks when key is turned on.

Does the vechicle have a fuel/oil pressure switch sensor located on it somewhere?

Any suggestions?

Answer
if they relay click then your getting power to that point.  and i think there is a fuel pressure relay there too. , hmm.   have a garage or dealership go over it and see if you can find it. short of getting a mutilmeter and testing wire that are al over. i think the dealership stands abetter chance of finding it..
