I've been having random starting issues for the last 6 weeks. Turn the key with no start 1-5 times then all of a sudden it will start with a turn like nothing is wrong. Sometimes it will take a week for it to happen again...sometimes a couple days. I've taken it for service to twice. Of course it won't happen for the service crew. They've switched out the starter, but it happened again later the same day. Growing frustrated. I've noticed others have had this issue on other boards, but was wondering about how to solve this issue?
Also, when the starts fail, the lights work fine so I don't think its a battery issue, but...
I would check the tranny linkage... I only say this because I had similar starting problems with an automatic F100. Now, this is a 1972 F100, and I know there could be a ton of other culprits, but I would start there.
Blacked out 07 JKUR, safari straps, Treadwright 35's on stock rims and Spydertrax spacers, stubbied front bumper, trimmed flares, 2" body lift, 2" spacers in front with 1" spacers in rear, Gen Right Tire carrier, more to come!
My 07 was doing the same ramdom not start, Try moving the shift lever around when it won't start or put in neutral. If it works, either have the dealer try adjusting the cable or it could be the "shifter postion sensor" in the tranny.
