THERE IS A SHRADER VALVE LOCATED JUST BEHIND THE INTAKE MANIFOLD. LOOKS SIMILAR TO A PSI VALVE STEM ON A TIRE. REMOVE THE CAP AND RELIEVE THE PRESSURE JUST AS YOU WOULD ON A TIRE.
Bump the starter, in other words turn your ignition(key) to start just long enough to turn over engine but not start. This is the metheod the haynes manuel uses for a 95 Nissan 4x4 w/fuel injection. It releases compression in the FI system, but since the engine isn't running(if it's running it needs more fuel pumped from gas tank)and since all FI is computer controlled...no more fuel is pumped becase the engine isn't running.
I own a 95 silverado 5.7 and when I turn off the engine, the fuel pump stops running and there is no more pressure in the fuel lines. It's most likely the same on your 93.
The old stand method - Pull the fuel pump fuse, turn the engine over with the fuse removed (engine may run momentarily as it uses up the remaining fuel) and viola no residual pressure in the fuel system. Don't forget to put the fuse back!

How do you relieve fuel system pressure on a 2001 Chevrolet Silverado?
Remove the gas cap, and then look for a Schroeder valve on the fuel rail. If there is no valve, then you cannot relieve the pressure. Just be prepared for a spay of fuel when you take the fuel filter off. Wrap a rag around the coupling as you loosen it.
