The 2001 7.3 excursion wouldn't start today. There is power to the lights etc. When I turn the key I can hear a relay, solenoid click. No engagement of the starter. I was late and I didn't get chance to see if there is power to the starter. It is the original starter 210,000 miles.
Any ideas would be appreciated.

 

Perform a Voltage Drop Test to see if the Solenoid is receiving System Voltage when the key is turned to Start. If so, it's the Solenoid / Starter. Often, the Solenoids can be cleaned really good to restore them. They're just a wrapped electromagnetic coil with a single shaft in the center.

If you don't see system voltage within .5 VDC look for a wiring / resistance issue.

If it's the starter. I hear good things about the Denso High Torque. Don't know cost or anything else. But several vehicles I work on have them and the owners say they love them.

 

Thanks Tom
I'll check it in the morning and post.
I have a Auto zone starter I purchased a few years ago. It's the 3 hole higher torque from the 03 model 7.3. From what I can remember.

 

I was the starter.
I put in a Auto Zone starter from a later model 7.3. Seems the Denso is the starter of choice. For around $300 plus. 1 or 2 yr. warranty on line. That was 2 or more years ago when I did the research. I purchased an Auto Zone starter for around $240 several years ago. It was on the shelf ready to go when the OEM with 220,000 miles quit. It has a life time warranty and can be replaced with no hassle. It might take a few days to get one if you ever had an issue. I kept my old starter and will replace the solenoid and check the brushes. It will be good enough to get me by while I locate the free replacement if that were to happen. The Auto Zone starter is a Mitsubishi copy. I has 3 attachment holes and is a high torque starter. The old starter only had 2 holes. If you have the two holes were the bolts go then you have the old design. There is a 3rd hole in the block for the this high torque starter. I purchased bolts from Ford to obtain the 3rd bolt. I used the 2 bolts that were with the old starter and one replacement bolt. The old bolts fit the treads tighter then the replacement bolts. The new starter is a lot quitter then the old starter ever was. It is almost 1/3 longer then the old starter. The 7.3 now starts like a gas engine.
The part# from Auto Zone is. DLG5154.
The paper work that came in the box references the starter as a Mitsubishi M8T50072 Planetary Gear Reduction starter 3 hole attachment points. . The paper work also references the Nippondenso starter that looks like the starter that came out of the EX. 2 hole attachment points.


Thanks again for all the help FTE. You guys give us PEACE of MIND knowing the brother hood is willing and ready to help.

That Mitsubishi PLGR three-bolt starter is the one on which I would spend my money if I ever had to buy a new one.

I believe that particular starter, the M8T50072, is the best motor that ever started a 7.3.

Others may have a different opinion, but I'll stick with mine.

I agree Pop.
So far . I'm impressed with the performance.
