i have an 04 f150 crew cab fx4 with the center console shift kit. truck only has 50k on it and wont start due to neutral sensor problem (says mechanic). sensor was replaced and problem still occurs; truck doesnt even try to start. it only happens in the cold after its been sitting overnight any suggestions? also im looking into a chip to give me more horsepower and better gas mileage to work with k&n intake kit, is this a good idea or should i leave it stock? thanks,
jeremy

 

Is this a crank no start problem or a no crank no start problem?
Could be fuel pressure problem caused by a injector leaking down. Injectors were a problem on 04-05s.
