I've got a friend troubleshooting a D6H Sn 4GG00334 that just died on site. Operator said there was a pop and everything stopped. My guy checked all the usual stuff, air filter, fuel supply and tried bleeding the injectors. Says fuel only dribbles out when he pumps the hand pump and the same when he turns the engine over. I'm thinking there is a problem with the pump and it needs to come out. Before I tell him to do that, I was wondering of other issues. How does this pump get timed to the engine? Last time I did one of these of these it took a timing on the end of the pump shaft. Here is a photo of the pump.
