Ok I have a 04 fx4 with a 5.4 3V. I just changed plugs and Coils, fired the truck up it ran great. I was running it for about 5 minutes then I had to shut it down to move my car (keys on the same ring). When I went back to crank it, the truck wouldn't turn over. It powers up but doesn't turn over at all, almost like the battery is dead. All I get is a click noise. What does this sound like? I have done numerous searches and the only thing I can figure out is maybe its possibly a PATS issue. I just don't know how this could happen when it was just running fine. Please Help.

 

Like the constant fast clicking? Check your battery cables, maybe you moves them while doin plugs and the vibration from starting it moved it enough to not start again. Did you check the voltages from battery

 

Its not a fast clicking, it clicks about 2 times a second as long as your trying to turn over the key. I have checked all the cables, even took them off to clean and ensure good connection.

 

Sounds like dead battery

 

I agree, dead battery or loose cable man. I know that clicking sound well, unfortunately.

Edit: Oops, I see you checked the cables already. Also I noticed on mine the speed of the clicking is related to just how bad the battery is.

 

Of course I cant find my volt meter, I will run to autozone to get the battery tested. I hope you guys are right.

 

Well it was just a dead battery, it baffles me how quickly it died. One minute it runs like a champ, the next minute nothing. Anyways thanks for everyone's input.

 

That's how they have always done me. At least on this truck.
