Engine runs rough. NEED HELP

to make a long story short, the fuel safety switch on the passenger side of my truck always seems to get hit by someone that rides in my truck and it never fails that it gets hit. so today my buddy rode with me and he hit it twice, the first time it reset and the truck was fine then he hit it again but after trying to reset it the truck just doesnt want to run smooth. i went immediately to advance to have it tested and it said cylinder 1 2 3 misfire lean. has anybody had an issue like this with the switch and or being lean? i read somewhere that it might be the oxygen sensor but im not 100% sure. i did bypass the switch just in case.

I never have to worry about this happening, I purposely load the front and rear seats up with crap so nobody ever rides with me. I would say that plug is shot from getting kicked too many times

Darn, forgot to say you might have air in the fuel lines too, considering when the reset kicks in it cuts off the fuel supply

Quite embarrassing, I actually have no idea, I apologize for giving the impression that I understood things. Sometimes I have ideas, but I don't know how to fix things

You should never have air in the lines, even when fuel sender quits pressurizing no air will enter.

You will slowly leak off pressure but youll never gain air.

Quick way to check fuel pressure is to cycle the key to the "on" position but do not start the truck up. pop the hood, and on the fuel rail there will be a small valve, like a common bike valve except slightly smaller. unscrew the cap off and press the center pin with a point object. be very careful, wear glasses because fuel will spray very quickly.

This is all in assuming fuel pressure is the key here.

Clean IACsensor, TB, MAFsensor. I know these have nothing to do with cut off for fuel. Never hurts
