Posted her a few weeks ago. 2003 f-350 had no dash lights and no start or crank.. found battery cable junction on left fender broken fixed... replaced starter. drove it sunday went about 15 mi and just shut off. towed home was a battery, replaced battery now I have lights but turn key and nothing ?was starting fine, all summer seems like a cold weather issue. Any relays I should be looking for ? I was going to check power to started but raining too hard this am


Any ideas

 

starter relay.
loose cable at battery
loose cables at starter
bad/loose ground connection.
defective New starter. does happen .
defective New battery. also happens.. more often then starter.

have battery LOAD tested... 100 amp LOAD test (most auto parts stores do it for free)... all other tests are a waste of time.
then work on connections.. and relay.

 

Clean your battery terminals and cable connections with the proper wire brush.

Check your alternator for proper output.

 

Ok thank you for all your ideas, but so this may help someone else!!!! I disconnected the starter solenoid wire on rt fender no starter movement, had 12.4 v at hot lead at starter. pulled starter out , bench tested it worked fine. wound up being mounting surface on engine was rusty cleaned it with sandpaper now it starts.

 

You will remember.. the next time you replace a starter... clean before assembly...

as far as that goes.. any new part...

glad you got it figured out AND up and running again.
