86FUBAR Posted January 28, 2011 Share Posted January 28, 2011 I wouldnt say the carb is in need of a rebuild , it may be something is as easy a clogged fuel filter or a bad pump . You have already established that you have spark by spraying brake cleaner in the intake and firing it up so next you need to check fuel pressure and the filter , to check the pressure your gona need a pressure gauge . If you ain't got one go down to the parts store and get a vacuum/fuel pressure gauge as it's two tools in one . Disconect the fuel line from the carb and slip the ruber hose over the end of the hard line and secure it with either a hose clamp or zip tie and have a friend crank it over , it should be around 5-7 psi . If it's within spec pull the filter housing off the back of the carb and inspect / replace the filter . Now what I recommend you do is remove the hard line from the carb to pump and cut hard line in a convenient location near the front part of the engine and then cut the the inlet portion of the hard line and leav enuf room to install an inline filter with ruber hose and ditch the internal filter as they are difficult to get at and the filter housing is easily cross threaded . Also by doing this you can "T" into the line and check the cranking / running pressure which is how I prefer to check it. Link to comment Share on other sites More sharing options...

Pete M Posted February 6, 2011 Share Posted February 6, 2011 I've been told that the FI system in an early 90s Camaro is fairly easy to wire in. Bonus that it comes on a 3.4L v6 that goes right in to your truck reusing the mounts and exhaust and trans. :D Link to comment Share on other sites More sharing options...
