Question about 1997 Chevrolet C1500
I don't know liter size of engine? I need fuel pressure spec?
If you have the spider fuel system, that system is noted for problems. Usually the start up fuel pressure is 60--66 psi, after it is running, it will run with less pressure.
There used to be service bulletin on the spider fuel system for sticking poppet valves on first start up of the morning. Then it would usually run fine the rest of the day. The fix was to clean the poppet valves. The cleaning procedure I saw was a shop procedure.
If it isn't a fuel issue, engine cranking, the vehicle systems get battery voltage, engine running the systems get alternator voltage, that can be several volt difference. Any applicable trouble codes?

re-torque the intake manifold bolts in the proper pattern. also check that the hose from the filter to the throttle body is hooked up correctly with no air leaks

There is None to my knowledge.. Ive done thousands of them.. Its way too hard to explain.. I did my first one by the seat of my pants.. only advice I can give is : Dont mix up the pushrods!! If ya do,, it'll warp valves bc the intake and exaust push rods are different lengths

THE FUEL PUMP IS BAD.
if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.
and i doubt that you are seeing enough fuel pressure to run a vortec engine.
low fuel pressure equals a non running vortec

That normally means that you have a issue with your gas cap try replacing your gas cap first then diconnect the negative terminal of the battery for about three minutes to clear the memory and start the truck again
