2003 f-150 no start

[huddys2]

4.2 Engine turns over, wont start. No brake lights, fuses good. no running lights in rear. Fast blinker right front, nothing on left front or back. no reverse lights. Replaced rear running light bulbs, old ones looked good. Replaced at the local Ford dealers suggestion the ignition switch, no help. Any help would be appreciated!!!

>4.2 Engine turns over, wont start.

This means that your ignition switch is getting power and sending it to the starter solenoid when you turn the key to the start position, if the engine is not starting your engine computer, ignition system, or fuel pump (or all of the above) is not getting power.

>No brake lights
>no running lights in rear.
>no reverse lights
>Fast blinker right front, nothing on left front or back.

This means that all of your lights on the back end of the truck are not getting power.

Blinker on the right front is getting power and is flashing fast because the turn signal on the right rear is no longer in the circuit to give the correct load to make it blink normally.

Nothing on the left front or back is because both bulbs are no longer in the circuit.

Even if the ignition is off you should still gets brake lights when you press on the brake pedal.

OK, what this sounds like is someone worked on your truck on some neat project that did not know what they were doing and messed it up so badly that they now do not know how to undo what they did and fix it.

OR

Your truck went through water way deeper than it was supposed to and now you have massive corrosion in the wiring.

OR

You have several connectors that have (somehow) come unplugged, I would start here first and make sure every single connector that you can find is plugged in.
