    Can anyone tell me the exact timing on my truck? I recently put a new motor in and my shroud isnt original and that's where the timing set should be. If anyone could help me out I would appreciate it. Thanks

    O degrees...

    ...be sure to disconnect the tan/black single wire connector (outboard of brake booster), otherwise the computer will attempt to compensate, and then reconnect when finished.

    Yeah, it's 0 degrees. Timing is controlled by the computer. To set it, make sure you disconnect the ESC from the computer. Should be a single wire I think under the dash...

    If you don't have a timing mark on the front cover, you're not going to be able to tell. Sounds like your going to have to pull the driver's side valve cover and look for TDC on cylinder #1 and figure it out from there.
