so long story short, went to replace throttle cable then went to start and test out, didn't realize cable was too short and started it up with intake slightly open heard a loud click/clank, got cam/crank sensors not synched, pulled opda and replaced just to be sure, did tdc and all, now got a crank-no start and no communication to any code readers, any help is appreciated

@oogah If the cam/crank are out of sync with OPDA it can cause a no start issue. You can also experience a rev limiter if they are out of sync. I am glad you found the issue! If you ever have any PCM issues I know a guy!!

@AndyG Thanks for the tag. Cookie and I spent the blustery weekend feeding our turtles and fish. Cookie is mesmerized by the turtles!
