2004 F-150 just "clicks" when key is turned
I have a 2004 F150 5.4L and recently it (every now and then) would delay starting. When I turn the key nothing happens for a few seconds then it would start fine, not sluggish at all. Today I went out to start it and nothing but a single "click". I tried it a few more times to see if it would start and nothing but the click every time I turned the key. Battery is brand new, only a couple of months old. I spent my day doing/checking the following:
*cleaned battery and ground connections
*tried jumping it
*checked fluid levels
*replaced starter and solenoid
*tested fuses
If anyone has any suggestions, I would greatly appreciate them!
