    1999 f150 4.2 swap with 3.8 mustang block

    on the advice from a friend mechanic, there's two diodes in the fusebox under the hood.. sometimes they don't get a good connection. they're black and look like small fuses, basically took them out and put them back in the same place and the truck started up. really a weird fix. but it worked.

    which camshaft synchronizer tool to use on 1999 F150 4.2 V6? grey or yellow?

    well that didn't work either. would crank and kind of hit every once in a while, then kick back randomly. so is still out of time. not sure what to do.

    which camshaft synchronizer tool to use on 1999 F150 4.2 V6? grey or yellow?

    that makes sense to me.. if its at TDC then the tang should be in the center of the notch. having tried both tools that sets it barely in the notch on one side or the other... this is definitely worth a try. will do it tomorrow, weather permitting. thanks brother.

    1999 3.8 V6, timing marks on harmonic balancer, where is TDC?

Now, I just got to get crank synchronizer tool to set that and should be...
