CHEVY FUEL INJECTORS FLOOD THROTTLE BODY

1990 Chevrolet Cavalier

Engine Mechanical problem
1990 Chevy Cavalier 4 cyl Front Wheel Drive Automatic 160000 miles

The problem started as a no-start, engine cranks, would not fire. It behaved as if it were fuerl starved. My mechanic, a man with years of experience, has replaced the injectors, throttlebody, coil, crank position sensor, ECM, and temperature sensor. After the injectors were replaced we always get the same result.

If we deprive the engine of fuel and use engine starter fluid, the engine starts and runs until it is out of fuel. If we connect the fuel line, gas floods the throttlebody as if someone has turned a water faucet on full blast. The throttlebody floods in less the a second. The mechanic forced a ground on the fuel injectors and they worked properly. HELP PLEASE.

The computer grounds the injector thru its driver circuits might not be switching
