Hi, Have posted a question some time earlier about my truck on start up running rough or erratic for short period then clears up and runs fine. Could any one enlighten me on what the overflow valve on the fuel pump does and could this have anything to do with my problem. I would really like to solve this issue.

Hi Joe, someplace within the last month on this site there was a thread going about a gent that had stuck injectors in his DM series truck. There are special tools out there available to force them out but I would soak the injector hole cavity with a penetrant oil for a couple of days to possibly loosen them. When reinstalling injectors be certain to coat the outer body with an anti seize paste prior to installation so they don't do it again possibly.

Here's a quick link to get you started. There are about three threads pertaining to this gents problem, and solution.

Thanks Rob, very helpful I thought about loosining the nuts a bit but was'nt quite game.

That pulley thats pictured looks good but not quite sure how it operates.Thanks again

Your injectors are suspect. I'd pull them and send into the fuel shop for calibration/rebuild.

They seem to be stuck in the head solid got 2 out of 6 free any hints?

Thanks Joe
