i jsut bought a 87 f150 and it ran fine untill i gave the guy the mony ,now it does nothing. the lights on the dash and the fule pump come on but thats it nothin with the engin or starter. the other thing is i can take the key all the way out of the ignition and the fule pump and dash light stay on.i can jump it off the solinoid so i know it runs fine its jsut i cant start t with the key. and sugestins would be aprsheated.

first off, use spell check. next sounds like it may be the solenoid, right next to the battery, trace the positive cable, that thing its hooked to, replace it first...

i replaced that and nothing changed. i also replaced the starter.

what about the switch on the top of the steering shaft under the dash?

gunboy111

do you know the name of the swich, so i can look it up in the manual

ignition switch. its hooked to a bar that connects to the lock cylinder (the thing your key goes in) as far as the key coming out while its running that would be the lock cylinder. mine does the same thing, you dont even need the key to start it.
to change the ignition switch you would need to take out the two bolts that hold the steering column up, make sure you mark the on the steering column where the old switch is, if you dont it will be aggervating trying to get it lined up right..

i jumped to quick, check the battery, and all the cables then go to the ignition switch

ok thanks. so you think i shood replace the ignition swich and the lock cyilinder?

benbailey84

first check the battery, advance can do this for free, if its fine then go to the ignition switch and lock cylinder. the lock cylinder dont have any electric connections so it wouldnt cause it to not start. also did it start with the key before? also you would have to turn the key about 90 degrees to get it to start. (3rd edit, lol,) to replace the lock cylinder requires a few steps in the right order, follow the directions in your chilton manual. i could walk you through this if needed with pictures if you give me a few days, it takes like 10 min to do.
