02 7.3 no crank

Two days ago my starter acted like it ha no power when it started to crank after sitting. Now last night turn the key just a click from the relay under the dash. Took out my nine iron and gave the starter a couple bangs, go to start and starts with no problem. Same thing today played around switched the relay for the starter with the blower motor, checked good. Two days ago I took the starter to advance they said it tested good, it's only 1 year old. Please help

I have used/heard hammer, tire iron, rock and lots of other stuff...but nine iron is a new one. Nice lol

Subbed cause I want to see what other guys think. Other than connections I would have said starter

I'd think it's the Starter, no matter what the Parts Store says....

Here's what happens, any why "banging" it fixes the problem. You have Two points that can get, physically, stuck in place AND a burnt spot on the commutator will prevent contact and with it. The two points are the Brushes in their holders, and the Bendix (the solenoid on the starter itself that pulls the gear out to the flexplate and makes the contacts to power the starters motor) can bind in a position that its magnetic coil isn't strong enough to pull it out of.

So, a couple of good "Whacks" and the commutator rotates a bit, the brush drops some in the holder, or (the most common) the Bendix arm resets and it starts again!

BUT, you take it in for a Test and none of those problems exist at That Moment, and you're told "It's Fine, we checked it"....

Starter for sure I bought one from NAPA a couple yeasr ago did the same thing 2 days later .They tested it said it was good tryed it again with no crank replaced it 2 more times to get a good one. All these starters had various problems. If you have a starrter alternator repair shop close by that would be the best route. Shaking and bumping during removal loosens the brushes or disc in the solenoid to get a good contact. Parts house test doesn't do anythig but check freewheel speed. POor test
