Hello. So recently I have had to replace the door blend actuator in my f150. in order to remove it I had to cut the back part of the metal bracket holding in that module under the foot hvac duct and that duct in half to get it out. I put everything back together and verified the actuator motor worked. However now my truck won't start. Is there anything at all I can check under the dash anywhere that would cause my truck not to start? It turns over but no start. All of the fuses are good and also tried swapping relays around with no success. Tried unplugging battery for 5 minutes and nothing. Tried blowing the horn, setting the panic alarm off, playing with lights and dials and everything. No luck. any idea what I could be missing here? I really don't want to have to take this truck to the dealership in town.....

 

If you have the owner's manual, it will show and explain what you should know about the inertia switch.

If not I will try.
There should be an inertia switch at the firewall directly over the tunnel where you were working.. It has a little red button that when tripped will rise up and now the fuel pump won't work Poke around there and if you find that button try pushing it down to reset it. If you found it went down, now your truck should start.

 

That was also something I had checked and forgot to mention that. I did notice and according to AI that my guages did not sweep initially on the on position and AI says that it could indicate something wrong with the run feed to the ignition. Not sure about that

 

Just a simple jump start it can you? Get a voltmeter and measure the voltage first and what is it.

 

Just to clarify you have to have power up at the ign sw in order for the engine to crank over.

If you have a test light or voltmeter ,,, with the key in the on position do you have power going to the coil or coils ?
