so there's no way at all. that the computer will let it run and just smell rich or leaned out or anything hu?![Think... :think:](https://board.marlincrawler.com/Smileys/marlin/think.gif)
It might turn over and run, but how well would have a lot to do with how far out of timing the gears were placed, and were they both placed the same way. The one above one was early and one was late.
The ecu can only adjust the timing w/in its set parameters, same w/the rich/lean air/fuel mixture, and only for properly installed/working equipment, not installer error/equipment failure. If one/both cams were off a little it might run alright, but if it was running the engine lean you would burn the valves rather quickly one/both heads.
It is easy to check, just set the engine to TDC, pull the cam gear cover and see where the gear marks are on the backing plate.
What is the symptoms you are having? Did the engine run for awhile then let go?
