    Probably leaking from the throttle shaft, could be from the timing piston too. Pull the pump and inspect it and have the right seals fixed, not too bad a job.

    Yeah, it's probably leaking from the throttle shaft. That would be causing your hard starting problem. It'll probably keep getting worse until you get it fixed.

    How many miles are on the pump? You might want to replace the pump or have it rebuilt. If it's got low miles, just replacing the throttle shaft seal will suffice.

    Thanx, everyone for response, i don't know how many miles are on the pump, i recently bought my truck, i think i'll use it until i get enough money for a rebuild, how much do you pay for a pump rebuild?, thanx.

    Here is the best price I've found so far:

    A member over at the Diesel Page just had a pump rebuilt by this company, and he is very happy with the results. They rebuilt his old 6.2L pump to the new 6.5L 4911 specs for $175 plus shipping. When I had my pump rebuilt locally in 1996, it cost me around $350.
