Hi,
I have a 1999 F150 with the 4.6. My dad and I replaced the radiator support and now it won't start. It ran fine before but now it won't start. I've tried a lot of things to get it to start and none of them worked. I tried leaving the key on for 15 minutes and then starting and that didn't work. I also tried using two different keys. I'm stumped with what it could be. I'm thinking that it has to go to the dealer now. If anyone has any ideas that would be great!

Thanks

check the grounds in the area. if the light is flashing it disables your ignitions

my dads 99 does that alot the theft light flashes and truck wont start so he just presses the unluck botton on the remote on his keys and it starts idk if u even have a rmote but that usualy works for us

My 99 did this once but I hadn't worked on it prior.I dropped my son off at daycare came out to start the truck and it would turn over and that's it.It ended up being the fuel pump relay switch or whatever it's called that keeps fuel from the engine in case of accident.It's the only time it ever happened but never happened again idk just a thought.

I've checked some of the grounds that I could see and they all seemed fine. There were only two grounds on the radiator support and those are fine. Also, it doesn't have keyless entry so the unlock button idea isn't going to work.

I checked the fuel pump relay and that's not what it is. Thanks for the ideas.....keep them coming!

I forgot to add that the odometer shows up as dashes only (-------).

Weird,You try unhooking the battery?

Yup, I've tried unhooking the battery. It didn't work. I'll have to try that other link you shared. I've done some research and apparently the PATS is not communicating with the computer or something of that nature.
