Is your 6.7 Powerstroke cranking longer than normal before firing up? Surprising to some, there could actually be numerous reasons to this, such as fuel injector or injection pump failure, low vattery voltage, or a bad starter. That said, more times than not, the starter is on its way out and needs to be replaced. While you could swap it out with an OE quality starter, why not make an upgrade? By upgrading to a Powermaster Ultra Duty, you'll realize faster, more reliable starts every time thanks to the 4.75:1 gear reduction design and 4.0 horsepower motor packing 275 foot pounds of torque.
