My truck snapped the crank. It broke the block so I bought a used block out of a HD truck and dropped it in. It cranks over, I fixed the codes it was throwing, but won't start. I have no way to set the injection pump back to where it was because the housing broke, and I used the one on the HD. I thought perhaps it was 180 out, so I pulled the valve cover, it's on the compression stroke, and I pulled the water pump and the dots align on the gears. There are 3 wires that I have no idea of their purpose, or what the connect to. Can someone tell me what they are and where they go to? Maybe that's part of the problem? Thanks G
