usual causes are 1: dirt/water/crud in any or all parts of fuel system 2: old fuel pumps crap thier diaphragms and bits get stuck in carby 3: most sierras are very old, and reco carby is needed. With my old Sierra, I cleaned entire fuel system, including tank, then fitted a high quality long life inline filter (efi commodore I think) A new fuel pump, and extra fuel filter after pump, and did a minor carby reco kit. Never had a carby problem again. A bit of metho in fuel once a month helps break up water, so it goes through better |
