truck wont start, clicking when key in ignition all electronics dead
 

I have a 2005 f150 with a 5.4 v8 i went to a buddy's house and parked with no problems. about 4 hours i went out to start my truck i used my key-less entry without any issues. when i inserted the key and turned one click all the electronics went dead and i could not start the truck. i was able to get it started after jumping it. then the next day i tried to start it and when i put the key in it died again. after i took the positive battery terminal off and reattached it and i was able to start truck with no trouble. I tested the battery and it is working fine I also tested the alternator and the starter and they are all working. I have no idea what is causing the issue but when i get the truck to start i don't have any issues with stalling or loss of power and it drives just fine.

i need help ASAP i need this as a daily driver and i don't want to spend the money to take it to a shop

Sounds like you had a corroded battery connection. I'd clean both of them and the battery cable connectors, then, hook them back up.

Thanks jack!

Ill go and try that and see if it works

You may try this too after you get the terminals cleaned up...

thanks i saw that at my local auto parts store but i didn't know if it was any good so i didn't buy it but I need to go back later this week so ill pick some up.
