Re: 95 Jimmy 4.3 Vortec starting problems - weird
Getting the plenum off isn't hard, just tedious with all the other stuff you have to unbolt first. I had a similar hard-starting problem on my '96 and it ended up being the fuel pressure regulator which is right in there on the back side of the injector assembly. Measure your fuel pressure...if it's below 57psi, change the regulator. Hope this helps!
