No, the vortec will be about 60 psi. The 1990 throttle body system will be about 15 psi.
Check the pressure regulator, fuel filter and fuel pump.
52 psi
no the vortec is computerize and that runs the fuel pump At a greater pressure than be atained by a mechanicle fuel pump.
gmc sierra 1996 feul pressure test
That is were the fuel injectors are at, and the fuel pressure regulator is on the rear of it.
60 to 66 psi
An electrical fuel pump.
About $14.00 for a good 1.
Above 60 psi if it is a CPFI= Central Port Fuel Injection. wish I am sure it is, all Vortec engines have this CPFI.
It is in the throttle body.
Blown fuel pump fuse, faulty fuel pump, or clogged fuel filter.
A 1995 S10 with the 4.3 L TBI requires 41 to 47 psi fuel pressure.
