Our '99 F150 died after slamming on the brakes while turning the steering wheel. Now it will not start. It almost sounds like it's locked up instead of the clicking sound you normally get with something like a dead battery. I read elsewhere it could be a dirty IAC. Anyone have a similar problem or any suggestions where to start looking?

 

Please clarify - are you saying that the starter won't spin the engine, or are you saying that it spins but won't fire?

 

It isn't firing. It sounds as if it is attempting to turn.

 

Check the battery connections, battery, and the battery cables at both ends.

 

Thank you, will check those too.

 

If the starter is spinning it over at a normal speed but it's not firing, check the fuel cutoff inertia switch behind the passenger kick panel.

 

what he said

 

New starter. New battery. The fuel shut off was not tripped. At a loss????

 

Do you have fuel pressure? There's a Schrader valve on the fuel rail for testing. Can you hear the fuel pump prime when you turn the key on?

 

The problem was the air conditioner compressor. Apparently when hitting the brakes and turning sharply there was enough force when the pitman arm hit the compressor jamming the pulley. Took compressor off and replaced with bypass pulley.
