I'd start out by changing fuel filters and making sure you've got a good steady stream of fuel to the pump. Then recheck your timing. Make sure to turn the engine in the normal direction of rotation as you line up the mark on the flywheel with the pointer. The backlash in the timing gears can throw off timing several degrees if you turn the engine over backwards to line up the timing marks. Also check the return line to make sure you got all of the chunks of flex ring cleaned out. If all of this fails, pull the pump back off and send to a injection pump shop. It is rather difficult to confirm that an injection pump is working as it should after repair without a test stand.
