There is a shaft that used to drive the dist... & pump. It now drives the pump only. I'd suspect that you have something wrong. heh. Take out all the sparkplugs(at least 4 if you have a dual plug system), take off the cover that you removed to attempt to turn the pump drive shaft. Using a screwdriver, jump the small wire on the solenoid to the positive (red or battery side) big terminal. Be prepared for spark and the engine turning over. It should turn easily, and should rotate the shaft in question. If not, the pump will not pump. Viola. At least you'll know if the shaft turns.. There should be a 'dummy' distributor plug to hold the top end of the pump shaft, and it would be rather large compared to the pump shaft, as it would have a driven gear to mesh with the dist drive shaft turned by the timing belt...
