Here is my problem: I have a 2004 F150 4x4 5.4 V8 and I cant get the starter to turn. I replaced all the relays and fuses and all I get is a "click" from the starter nose coming out but wont spin. It has a new battery and a new starter.

you need to follow items in the above thread: wiring, battery, starter. When was battery and starter replaced - did the truck start with new components?

 

Time for a new starter.

 

Long shot but this did happen to me. Had a truck where the ground strap to the engine had a lock washer on it and it had about 1/3 break off. Apparently wasn't doing a good job on grounding the engine so the starter only clicked. Checked the battery, relay, starter etc and found nothing wrong. Wasn't until did some unconventional wiring/testing, we found that if we grounded the starter to the frame using some extra jumper cables it suddenly worked. Once we knew what was wrong, it was an easy fix.

 

Bad ground wire. Thanks!
