I've got a 04 f150 4.6, I shut the truck off and went to start it again and it just clicked once. So I jumped the solenoid etc etc, I have since then changed the starter, starter relay, and ignition relay but is still doing the same thing. Any ideas 💡?

 

Have you had the battery tested?
Also have you cleaned battery cables on both at the terminal and opposite ends?

 

Yes, i put new ends on the starter side of the cables as well so there shouldnt be any problem there.. and I bought the battery back in March of this year so I wouldn't imagine it's bad, it reads 12.1 volts with my ohm reader.

 

What happens if you put it in neutral? Will it crank?
Try turning the crankshaft with a wrench on the front pulley bolt to make sure it's not hydro locked?

 

12.1 is not fully charged. Can’t say that (battery) is your only problem. But I’d (and as others have suggested) start with proper load testing of the battery. Then move on with proper testing from there. Parts cannon is rarely cost, nor time effective method of diagnosing/fixing problems.

 

Finally, just drove it out of the barn... praise the lord I ha the ground hooked to the starter solenoid because I took it apart 3 months ago and forgot how it went back together. Thanks for the help. Glad I joined this group!
