My truck is a 98 f150 5.4 ltr. It had been kind of funny starting on really cold days this winter(sometimes wouldn’t fully turn over so I had to push on gas while turning key to start it) and one afternoon last week when I went to turn it on it wouldn’t start. I got it towed home and replaced the starter which had a broken wire on it (the braided copper wire). It did not start after that. We jumped it and it started one time, but very weakly and died after about one minute. I then got the battery tested and they said it was bad so I replaced it and it still did not start. Jumped the new battery to make sure it was good and still no go. When I turn the key I can hear juice for a moment and a click, but I cannot hear the starter spin and thats all it does.
I checked out the fuses, the starter connections, checked and cleaned the connections on the battery.
I have to decide tonight if I’m going to try to diagnose and fix it tomorrow or have it towed to a shop. What I need to know is how to test/diagnose anything that might be keeping it from starting so I can be fully prepared to get it fixed tomorrow(nice warm day). Please and thank you for any help!
