Hello Ricardo. When I turn the key to the the on position the engine light doesn't come on.
Jeep Mechanic: Ricardo Hohl, Master Certified Tech replied 8 months ago

hi sorry for the delay. if the engine light does not turn on with the key on it means the computer is either on default protecting the circuit from a short , or power and ground to the computer are affected. lest start with a possible short to the computer.
