You use a pressure gauge on the fuel rail underhood.

When you say "hard starting" is the engine cranking normally as in starter is turning the engine at the expected speed?

Ok - back to a pressure check. I don't have the range of norms at hand but know many Chevs are fussy with the right minumum pressure.

Also: Recently noted around here from friends in biz was a bunch of problems with wiring connections at plugs in the wires to the fuel pump and gauge on GM vehicles causing erratic problems and confused testing for a while. Pins on connectors showed that greenish/blueish corossion build up when opened up for inspection on those,
