The check engine light is on all the time now and when I start the engine there is a sound coming from the engine that sounds like a loud fan. If I turn off the engine and restart I do not hear the sound but the check eng, light is still on.

when the sound starts check the temp gauge and see where it is at
I'm thinking that you have a viscous fan hub and it cuts in when standing at lights or slow traffic or heavy loads at slow speeds
it will keep running until the engine temp comes down or you switch the engine off
or it could be a electrical controlled fan and the noise on shut down is the relay clicking off
Good morning I don't know what you are working on but possibly your ignition switch, that would explain why when you turn it off and then turn it back on it works. I don't know if this helps you or not. I know when your switch is going out you will get power to some things power not to others. I hope this helps you good luck
I would be very worried that sounds like the timing belt has split. would not drive the car until it has been checked a stall on and old belt can and will snape. check this out before driving car again...
Sounds to me like your jeep has what's known as the delayed start check engine light problem. Check to see if your check engine light comes on, when you turn on the ignition, at the times when the fuel pump is 'delayed'. If no check engine light comes on then your ecu needs to be repaired or replaced. Both options are available on ebay. The jeep will not start until that check engine light finally coming on.
SOUND LIKE ENGINE OVERHEATING,CHECK COOLANT LEVEL MAKE SURE YOUR RADIATOR FULL OF ANTIFREEZE.IF YOUR COOLANT OVERFLOW JUG IS EMPTY COOLANT LEVEL IS LOW.NEED ADD MORE COOLANT TO OVERFLOW UNTIL COOLANT STAY AT FULL COLD MARK. DONT OVER FILL COOLANT OVER FLOW JUG.IF COOLANT OKAY ENGINE OVERHEATING REPLACE THERMOSTAT.MAKE SURE ENGINE COOLING FAN IS WORKING IF YOU COME TO A STOP CAR SITS FOR A LITTLE WHILE START OVERHEATING THE COOLING FAN NOT TURNING ON , BECAUSE COOLANT FAN FUSE BLOWED OR YOU HAVE BAD RELAY,THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.IF YOU HAVE THE CLUTCH TYPE COOLING FAN, MAKE SURE WHEN TURNING CLUTCH FAN WITH HAND COOLING FAN SHOULD HAVE RESISTANCE WHEN HOT.IF CLUTCH FAN FEEL WOBBLY AND LOOSE REPLACE IT.TAKE VECHICLE TO AUTO ZONE OR ADVANCE AUTO PARTS OR ANY AUTO PARTS STORES THEY WILL CODE SCAN CAR FREE AND GIVE YOU THE CHECK ENGINE LIGHT TROUBLE CODE TO SEE WHAT CAUSING CHECK ENGINE LIGHT TO TURN ON.
Sounds like you made have a bad tempature switch/relay for the fan. When the check engine light is on have Autozone or a mechanic run the codes for you and see what comes up. You may even be able to scan it now and see what codes are in the memory and be able to base it off that.
SOUND LIKE FAULTY IDLE SPEED CONTROL OR FAULTY FUEL INJECTOR OR A INTAKE VACUUM LEAK.IF GETTING HOT WHILE STOPPING.CHECK COOLANT FAN FUSE AND RELAY.IF BOTH GOOD.HOT WIRE COOLING FAN TO CAR BATTERY USING JUMPER WIRES.IF COOLING FAN DONT WORK REPLACE THE MOTOR.IF FAN WORKS.COOLANT TEMPERATURE SENSOR IS BAD.ALSO HAVE CAR SCANNED TO SEE WHAT CAUSING CHECK ENGINE LIGHT TO COME ON.
Hi there. It sounds like your cooling fan and/or electrics associated with it might not be working correctly. Perhaps the reason for the engine light coming on is that your engine temperature is too high as a direct result of the cooling fan not working properly. If after starting the engine you don’t see, or hear the radiator cooling fan working, this is the most likely cause of the engine overheating. You then need to have either a Dealer or ServiceCenter identify why the cooling fan is not working – wiring/connections, fuse, sensor or fan motor. Hope this helps, Scottech.
