9 to 13 LBS.
A 1995 S10 with the 4.3 L TBI requires 41 to 47 psi fuel pressure.
Yes it is fuel injection. It is called a TBI / Throttle body injection.
YES, that would be a TBI / Throttle body fuel injection engine.
The fuel pressure regulator in that 96 GMC 4.3 TBI is located in the throttle body.
If just the fuel pump has failed you would still have spark. But, you could have serious electrical problems that caused multiple problems that included the fuel pump circuit and the ignition circuit to fail.
That is the round thing on the top rear of the TBI. The thing that looks like a carburetor.
9 to 13 LBS. PSI It must have no less then 9 and no more then 13
do you have TBI ?
TBI or TPI? 305 or 350?
Yes it does. It has TBI / Throttle body injection, Fuel system.
Its not a good idea cause this will have more pressure., the tbi its a low pressure compare to the iroc -z tpi
41 to 47 psi. _____ 10 to 12 PSI as it varies slightly from factory. The answer provided above applies to 1995 and up s10s with the 4.3 v6 and the newly added MPFI fuel injection system. In 1992 the fuel injection system was TBI (throttle body injection). TBI fuel pressure was set at 10 to 12 PSI from the factory.
