Not starting.

[newjonwayne]

Took the intake off today to replace the intake gaskets and after I put it all back together and relanded the ground on the battery my 2007 Yukon 5.3 will not start. It has no interior lights, locks don’t work, gear indicator line doesn ’t work either. Some lights do light up on the garage cluster but there’s no actuation of the starter at all. Before I started on it, it started just fine.

Go back to the last thing you touched… battery cables.
