I have a mid nineties 853h. There was a small fuel leak from the fuel injection pump so I thought I would fix it. ???? Help me dear lord what have I done. So like any red blooded American man I neglected to read the manual section on removing the pump. Pshaw, Who needs a manual right? Umm... This guy apparently. So, I didn't really pay attention to where the engine was (cylinder one should be TDC) when I removed it. I had it rebuilt and realized the mess I was in when I went to reinstall it. I consulted the manual. Oh hindsight, you fickle girl. the instructions say to position the engine and the use a dial caliper tool to set the pump. The problem is I can't find which port should be aligned. So, I took the left cover off so I could align the timing marks. Marks aligned, reassembled, Bob's your uncle! Hmm, I guess I don't have an uncle named Bob. It won't start. Turns over and I get smoke out of the stack, but where's there's smoke there's not always fire. So I suspect that I have the wrong port on the pump aligned. In other words I'm either 90, 180 or 270 degrees out of time. I could take it apart again and advance the engine then try it again but I potentially could have to do that three times. I am hoping that someone here can save me the first two tries. And just tell me what I should be doing. Any takers?
