Truck won't start after head unit replacement. *** solved ***

Man made errors or not, with the lead and assistance from @Dm93 and @TnShooter, it almost certain that’ll come to a happy ending.

With everyone following this thread and that epic engine teardown / rebuild / teardown / rebuild thread, we hardly have any time to argue over how often we should change the oil in our trucks.

There are some damned helpful people on this site. Helps a person overlook the ones who rarely have anything good to add.

 

This reminds me of Eric troubleshooting and fixing a very similar issue.

It just goes to show that a fuse issue is rarely a fuse issue.

 

Yes, fuses intercept other problems.
They are almost never “the problem”.
