1994 Chevy Silverado V8 Four Wheel Drive Automatic

I have a 1994 Chevy truck with 350. It idles and runs fine when parked. When I try to drive it, it acts like it doesn't want to take the gas. Sputters and knocks off, and is very hard to crank unless it sits overnight. I have replaced the fuel pump, IAC valve, egr valve and solenoid and fuel filter.

Verify the fuel pressure with a fuel pressure gauge designed for your system if its within specs if okay -Test the throttle position sensor, manifold absolute pressure sensor and also the knock sensor and verify the ignition timing

ANY CHANCE IT COULD BE THE FUEL PRESSURE REGULATOR?

If there's a problem with the FPR while checking the fuel pressure and you disconnect the vacuum hose to it and the pressure don't go up about 8-12psi its no good.
