Do you have a TBI (traditional round air cleaner) or CPI (black plastic cover with orange lettered 'Vortec') engine?
I would get yourself a fuel pressure gauge and hook up to the test port on the CPI engine or install the adapter (not included in most kits) if TBI. The CPI needs 55+ psi for proper operation while the TBI needs around 15-18 psi.

As I said, 55+ is what the FSM states for both the CPI and the SCFI. You really need to get a gauge on it to check the pressure. You will also want to observe the fuel pressure after you turn the key off. If it drops, then you have a leak in the system. And for the CPI motor, this is typically the FPR.
