I have a 2001 F150 Supercrew Lariat. About a month ago I stopped to fill up with gas and afterwards it would crank but not start. After a few tries the engine would no longer turn over. My battery was 7 years old so I replaced it and the problem went away for about 5 days. Then the same thing, crank but no start. I checked all the fuses & called the local Ford dealer. After talking with the parts dept. I tried hitting the panic button then the truck started. After talking to parts again I replaced the PATS transceiver. After 3 weeks with no issues the problem came back. This time I locked the doors with the keyless entry remote then unlocked them & the truck started. So I'm wondering what is my problem. Could it be the PATS module or something with the keyless entry module or some other issue. Any suggestions?
The last time that had happened to me 3 years ago it WAS the anti theft...The way I accidently cleared it was to remove the positive battery terminal and within 10 seconds, replace it...Has been fine ever since, MAYBE this will work for you in a jam
Well I had the issue again tonight. Engine would turn over but not start. The theft light was not on and all the displays showed normal. No dtc codes or other issue. Disconnected the battery(both cables) for two minutes and the truck started up. Anyone have any ideas????
Maybe it's your fuel pump relay. My truck doesn't have remote keyless entry, but it was acting just like your truck a few months ago....crank strong but no start. Replaced the relay, been good ever since. About $12 at Advance Auto.
My girlfriends truck is doing the samethhing, it cranks but won't start, I parked it in the backyard about a month and a half ago and when I went to start it 2 wks after I parked it and it turns over but it will not start. I'ts a 2001 Ford F150 5.4. I have checked the fuses and relays, all good. I cleaned all the ground cables I could find so far. Also hooked up my scanner and got a code for CHT, cyclindar head temp sensor.
