I have a 2001 f250 ext cab long bed 4x4 that I use as a feed pickup. I have had it for about a year now. one of the issues I have noticed since I bought it is the issue I am having with the flywheel/starter. Its very random like maybe I have a missing tooth or something on my fly wheel. but every so often when I would go to crank my truck over it would just make a little whirring sound and nothing happen ( like my starter gear isn't sliding out and engaging my fly wheel. After looking through my inspection cover I noticed I had a little wear on the sides but no teeth to my knowledge broken or stripped off. I noticed my starter had one bold loose but other two perfectly tight. It was also covered in oil and dirt from my truck sweating horse power I decided to replace my starter and have my original ford starter rebuilt. I replaced it with a NEW oreillys starter. I noticed it cranked about 5 times as fast but again every 10-15 starts I am getting the same no start. any thing I am over looking????? Thanks in adavance

 

btw I for got to mention my truck is a auto with about 190k on er

 

What I would do is take the inspection plate off and mark the flywheel when it happens again taking note of where the starter is engaged at. Then spin the ring gear to inspect. Sounds like a ring gear issue if multiple starters behave the same.

The engine had a tendency to stop on the same spot on the flexplate often times so you are probably hitting the messed up part.

Can you tell if the plunger is pushing the starting gear out?

 

To the best of my knowledge the starter gear is working properly. Ive heard that the starter gear will generally enguage in 1 of 3 spots everytime the motor starts...any truth to that? I know that it ususally will do this about 1 in every 10 starts. I will check it out next time it does that and see what I can see....Thanks for the advice!!!

 

due to compression there are only 4 positions a v8 engine will stop at




Over time with a cylinder with lower compression it can stop at same point more often

 

awww well that makes a lot more sence to me than 3......what started my problem in the first place just age on the flex plate? If I have to change the flex plate at some point is there a better one out there with hardend teeth or anything like that????

 

the more you start it, the more wear you get


If teeth are missing then that's your issue, go with ford part IMO
