Disconnect neg battery cable, safely raise vehicle, place floor jack under tank, loosen gas tank straps and allow tank to slowly drop halfway, disconnect( this is the hard part) fuel lines,and power connections at tank. Drop tank. With a brass hammer/punch carefully remove retaining ring/seal.Reverse to install. I have bought used low mile fuel pump assemblies at a salvage yards ( $75.00) because this new will cost you $300-$400 at the dealer. Don't use a cheap pump replace the entire assembly because this is a float/sender/pump/support in one. Replace your fuel filter too.
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.
On a 1995 GMC Jimmy with a Vortec engine, the fuel injectors are located within the intake manifold, specifically under the upper intake manifold assembly. To access them, you typically need to remove the air intake assembly and the upper intake manifold. The injectors are mounted directly to the lower intake manifold and are connected to the fuel rail, which supplies them with fuel.
you would need to change the cylinder heads also.See link below
It is in the throttle body.
the simple answer is YES. though, a 94 would be either a t.b.i. system or early vortec. if it is a vortec, the swap shouldn't require a p.c.m. reflash- however if your 94 is a t.b.i. you will need to change the intake and fuel delivery systems to handle the 60 p.s.i. operating pressure for the vortec engine.
A 1995 S10 with the 4.3 L TBI requires 41 to 47 psi fuel pressure.
Follow tube from fuel tank
57 - 61 psi for the 95 jimmy 4.3 vortec so it is probable the same
in the tank
A blown fuse.
It's fuel injected, No carb.
It would not be a bolt in and go swap. They have entirely different fuel injection systems.
