Not starting

[Bubbaprice]

2008 Dodge Ram 1500 2 door 4.7l 111000 miles

I started having starting issues yesterday. I thought it was just an old starter and replaced it. Truck started up fine after and this morning.
I tried to start the truck to go home after work and it is having the issue again.

Issue: Starter engages and turns the engine but stops after a one second. It does this over and over. After several attempts it will start. It varies how many attempts it takes.

Battery: 2 mo old tests fine under load.
Alternator: Tests fine under load.
Cables: Were cleaned within the last month while working on O2 sensor issue.

I marked the belt and was able to se that it moves each time I engage the starter, but the starter isn't engaging long enough to start the truck.

I am at a loss at where to look for possible issues. Any suggestions would greatly be appreciated. Thanks.

Without being there, i can only guess

It almost sounds like the replacement starter, may have the incorrect bendix or gear that engages the flywheel

I’d second the issue with starter. Even though new, sounds like starter issue.
