"95" s10blazer 4.3 vortex 229,000. miles... had fuel pressure regulator replaced 45,000. miles ago by mechanic $$$ ... lately been starting rough but runs good when going .... mechanic says i need fuel pressure regulator again ... can they go bad that soon ?

i'm pretty much mechanical myself ... is hard to do it yourself ? ... seems alot to remove to get to it & wondering if there's any sites that shows step by step?

anyone ?

 

its pretty simple to do..unscrew the 10 bolts that hold the upper plenum in place and remove the plugs from the sensors.they are all different plug ins and only go 1 way remove the 2 vacuum hoses from the rear of the intake and 1 from the front and remove the throttle linkage and set it to the side..the fuel injector spider assembly is under the upper plenum and the FPR is held in by a torx screw on the left side of the spider
