'96 Chev 1/2 ton 4X (Vortec) won't start after sitting for 8-10 hours
My truck starts fine when sitting for up to 8 hours. Longer than that and you're in trouble. It's the weirdest thing how it starts just fine anytime after it initially runs, but if you leave it overnight you're back to the "not enough fuel" problem.I poured fuel down the throttle box and that did the trick. I've replace the plugs and wires and had a tune-up done. One thing I have noticed is an absence of the high pitched whine when you turn the key ... I always thought that was the fuel pump engaging, but if the fuel pump wasn't working it shouldn't start or run anytime.
What's the answer to this riddle?
