Well, I know this is not a Chevy newsgroup, but the procedure in my Chilton
manual for my Chevy S10 is vague. It says to relieve the pressure before
working on the fuel system. It says to first loosen the fuel filler cap.
Then, if it is a TBI system (whatever that is) it has an internal bleed
feature. If it is a MFI system, it says to loosen the fuel line outlet
fitting on the fuel filter. Simply let it drain. Is that all there is to
it on a car like that?

Throttle body injection: there's only one injector, and it's
mounted on the throttle body (sort of below where the carb
would be if it had one).

Multi-port fuel injection: there's one injector per cylinder.

Sounds reasonable -- especially since the shop manual says so.

The fuel pump is in the gas tank. Loosen the gas cap and that
drepressuizes the whole thing. The pressure will be relieved through
the fuel pump into the gas tank. Filter is up agains the firewall.
Loosen the top nut first.

Only if the fuel pump has defective valves. That will NOT depressurize
the system if everything is working correctly.

The GM prodecure to relieve the pressure for the throtle body and mfi
S10 engines is to remove the gas cap and wait five minutes (as
explained in the manual) The fuel line pressure is relived through a
pressure relief orifice that allows the fuel back into the gas tank
once the pressure in the gas tank is relieved by opening the system to
the atmosphere.
The exeption is the 2.5 liter 4 cylinder engine (few s10 were equiped
with it). In that system, you pull the fuel pump fuse and start the
engine. Once it stalls, the remaining pressure is releived into the
intake manifold through the injector.
