Tried to start the truck and only got a click. Replaced batteries, but didn't solve the problem...only got a click. Engine will not turn over. HELP!! 1999 F250 Super Duty 7.3 Diesel

 

Check the starter solenoid behind the pass side battery next to the vacumn pump and then check all connections at the starter (make sure no corrosion there)

 

I would try crossing the solinoid in order to determine if that is the culprit.

 

My husband said he tried that...didn't work. Thanks!

 

Well, if the cable ends are clean, and crossing the solenoid didn't work I would either try to find another 7.3 psd to borrow one from to confirm a bad solenoid or replace it with a new one.
It sounds like the magnet isn't working.
Before you throw it out try tapping it with the handle of a screwdriver to see if the magnet can be unstuck.

 

Any chances the CPS is the culprit here?

 

Good News --- Problem found!
Bad News --- it's the starter. Lotsa $$$

Thank you for all your help!

 

I'm almost scared to ask, but what is a starter going to run a guy?

Any ideas of where to buy quality starters at?
