D'R34P3R

I was involved on a wreck no long ago, when I tried starting my truck it started and then hesitated after 1 or 2 seconds. Now it's not starting at all. Damages are minimal, but the airbag light came on. Now, I took the seats out (stereo system installation) and unplugged two cables...one is the power source for the seat motors and I'm assuming the other one is for the airbag. Would this cause the fuel pump to shut off? Or is there a shut off procedure done by the truck at the moment of an accident?

Also, I need to replace the lower control arms and I am wondering what's the difference between standard payload and heavy duty payload (04 f150 4x4 Lariat). Would any of them fit or does it have to be the same one? If so, how can I find out which one do I need.

Thanks!!

Owner's manual will tell you where your fuel pump intertia switch reset is.

Well, went ahead and checked that and no luck. It starts but it hesitates for a few seconds and then dies.

Mass air flow sensor maybe?
