Hello, I'm New to the forum and was advised to join by multiple people stating the help on here is phenominal, so here goes.

I have a 2005 Screw 5.4, The truck was running fine, went out the next day and nothing but a click (like the starter went out) So i replaced the starter and still the same click, I heard the relay pick in the fuse box, so i went to check the battery... Took it out, had it bench tested and it is all good, cleaned all grounds on the chassis and block and also the static strap connections then metered all the connections and they are all good. I tried to start it and got the same result, the engine actually turned ever so slightly as I had my son observe the pully's move about an inch. After I attempt to start the truck and then turn the key to the off position, the gauges bounce for about 10sec also. So far everything is checking out good, can the ignition starter switch actually cause this prob ?? Like I stated earlier, the engine turned about an inch, I'm just shooting out ideas here and I'm perplexed at this point. Any help would be greatly appreciated,,, Thank You

 

Another problem could be engine hydro locked from a bad injector . I would use good jumper cables and see if a running vehicle with heavy leads turn it over . Batteries only last for 3 or 4 years now .

 

 

I agree sounds like a bad battery or connection. A lot of times we see people say their battery was tested but it still turns out to be a bad battery.
