Re: Help with starting my truck please..
Ok, vapor lock the incorrect term, vacuum lock? TKO, is this the same truck you've had issues with before? If the venting for the gas tank has failed or become plugged, you're going to build a vacuum in the tank, which will impede gas flow, particularly if you've driven it for a while. Easy check: next time you drive long enough that you'd expect it to start hard, open the gas cap to equalize the pressure and see if the issue still resides.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
