1998 Ford Explorer CAR WILL NOT START-MESSAGE-AIR RIDE SWIT

In the rear of the vehicle will be a switch to turn the electronic suspension on ands off, that should fix that problem. Wont start? Or wont turn over? If it wont turn over, Could be a bad starter/solenoid. Check for 12 volts at the small wire on the starter with key in crank position. If it has power then the starter needs to be replaced. If none, then get back to me and we will figure out where it stops. If wont start, check for spark, and fuel pressure. Do you hear the fuel pump run when you first turn on th ekey?
