Starter grinding with no start

Hey guys, so it has been pretty cold here for the past 2-3 weeks (single digit to teen temps and close to 0 at night) truck starts just fine after letting the GP's do there thing, friday night I went to throw my plow on because they were calling for some snow, and the starter would just grind for about 1-2 seconds, simular to when you try to start a car that is already running. turn the key off, then back on let the GP's cycle again, go to start it same thing, then I try it again and it starts fine, i let the truck warm up, shut it down and i tried starting it another 3-4 times and it worked fine. I then went out maybe 4-5 hours later, truck sat with snow on it and it started up fine. woke up early saturday morning and truck started up fine, drove around all day and truck ran fine. Sunday I went to start it in the afternoon and same thing, ground twice before it started. Now I have search on every powerstroke site and no one seems to have a solution. I don't mind putting a new starter in it but most of the guys that this has happened to pt a new starter in and it just grinds again. The starter seems to turn the truck over just fine when it doesn't grind. What do you guys think? Truck is a 2002 auto with 180K miles on it.

from my experience, when this sound is present from motors im working on either the bendix (small gear in starter that gets thrown out and engages into the flywheel) is missing teeth or worn, same goes for the teeth on the flywheel..The started itself could be on its way out like you said..Another thing i run into is batteries being low and not being able to fully throw out the bendix into the flywheel..i would pull your starter and jump the solenoid manually with leads and a battery and make sure the bendix isn't worn and is being thrown out all the way..also but a socket/wrench on the crank pulley and turn the engine over little by little while looking at the teeth on the flywheel..

this is just from experience, hope it's helpful..good luck.

Thank you for the reply, I will prolly pull the starter and start there I guess. I'm gonna try and see if I can get a high torque starter from napa or somewhere. It did it tonight again. Hand to go fuel the truck up, started it up grinds for 2 seconds...then turn the key off and try again and it started right up...and it was 35 degrees out.

an engine typically has 2 specific spots where it starts and stops its entire life. this is why you'll often find paired cylinders which yield lower compression than the others. it is also why you'll usually find the majority of wear on a ring gear in 2 spots. check the teeth of the ring gear. use a mirror and turn the ring gear it's entire circumference for inspection

you will need a 15mm wrench for the three bolts that hold it on and i belive an 8mm for the small nut thats on the solinoid. FYI the top bolt is a C**KSUCKER to take off and put on (this is the one you need a wrench for) good luck and hope you got a warm and dry floor to lay on since you will be under that thing for a while.

the top bolt isn't too bad. what i usually do, after disconnecting the batteries, is disconnect the cable and solenoid wire, then once that's out of the way, use i believe an 8" extension and shallow socket to get on it. however, i usually use an air ratchet. but that should clear the starter and give you room for a good sweep

its really strange....its just a quick grind, its not even a grinding sound, its like when you start a car that is already running. then it fires right up....it does seem a little slower turning over now, i also had a diesel leak from the fuel bowl a month ago or so that i fixed, do you guys think diesel getting in the starter screwed it up?

Thanks for the tips guys! and no i will be doing it in the cold wet driveway haha....maybe i will tackle it this weekend in my parents garage...

I had a similar problem once and it ended up being a grounding issue. I ran a cable from the starter to the frame and it took care of the problem.
