I have a 1993 GMC Sierra pickup that has just started to act up. It ran fine one day, and the next it day it wont start. It acts like it is flooded. I changed the fuel filter, cap, rotor, module, coil, and spark plugs and it still won't start. The throttle body is alternating pulsing fuel into the engine, but no start. If I hold the footpedal down to the floor, it tries to start but still acts flooded, and tries to start.
Any Ideas?

Verify the fuel pressure if its within specs if okay and there's injection pulses-Double check for spark
