Under your intake manifold. Its a pain to change them, so do them all and clean out thee egr valve too. it is also under there.
vortec trucks have MPI Multipoint fuel injection. yes it's not getting enough electic to the wires to fuel pump
It would not be a bolt in and go swap. They have entirely different fuel injection systems.
well, the 93 has a spider injection unit in the intake manifold. ten bolts and a gasket...
you would need to change the cylinder heads also.See link below
It doesn't have a carburator. It has a throttle body fuel injection and a faulty fuel pump would be my first guess. This most likely has the 4.3 Vortec total fuel injected not the TBI
Above 60 psi if it is a CPFI= Central Port Fuel Injection. wish I am sure it is, all Vortec engines have this CPFI.
Yes it does. It has TBI / Throttle body injection, Fuel system.
1986 fuel injection came out and yes it is fuel injected
This fuel pressure regulator is a component part of the SFI (sequential fuel injection) assembly, sometimes referred to as "spider". It resides inside of the air intake plenum and is accessed by removing the upper half of the intake.
Yes it will bolt right up but the difference is the 1995 is a throttle body injection fuel system. and the 1999 is a vortec witch is totaly different. Intakes and heads are different on both engines.
first efi was 1966, but was not perfected or put into use until much later. the fuel injection on cars to day is port injection, before that was bank injection, throttle body injection, the vortec.
Yes
