1996 GMC C1500 • 327,000 miles

Engine stopped on the road, had to tow it home
Check for spark at spark plug and I have spark. Checked
For fuel flow at intake manifold and have flow but don't know the pressure I don't have a gauge. Engine turns over but won't start. Is there anyway to test for power at the fuel injector? Also this is a 5.7 liter engine 1996 does this engine have one injector or is it multi port with 8 injectors.

Actually it's called cpi but it should have 60-66 psi if you spray carb cleaner in the throttle plate and it starts it's pretty much a fuel pump but you can rent the gauge at a lot of auto parts.
