Starting issues

2017 Toyota Tundra won’t start at times. Replaced the battery and still same issue. So I figured it’s the starter. Bought a starter from the dealership and replaced it and still same issue. Had both starters checked and both came back good. So when I have the issue of not starting I turn the key and no sound. Everything still comes on, radio and lights on dash. So when it don’t start I go under the truck and tap the starter and it turns over and start. Need help with this issue!

 

Check your battery cables . I had that happen before on an old Ford and it turned out to be the negative battery cable . It was corroded .

 

Well if it starts by tapping probably the starter or a loose connection on the start. Do a wire wiggle test to eliminate the wire possibility.
