JEEP WONT START

could you confirm as OBD code sbegin with a P and have 4 numbers

What engine?

Do you use obd2 code scanner check the engine system and find out fault codes? How do you diagnose the Jeep?

call the dealers as i suspect a immobilisor fault ,unusual with a citreon to have a fualt like this ,normally its the bane of my life here for this and thats a renault .

with the key on the check engine lite should start flashing if not you'll need a code reader

Have you scanned the system for fualt codes? An O2 sensor will never cause the engine to stall out like this, NEVER.

Remove the distributor cao and replace the ignition module. Follow the wires coming from the outside to the inside of the distributor, this is the piece you need to replace.

well the quad driver may not be at fualt and most likely is not.

there is a fualt line that the computer uses to monitor for fualts but the thing is one line monitors four different things and the code is to get you in the general area but not to the exact fualt. so from here you need to test for failed components. that code and the quad driver monitors the a/c , evap solniod , egr solenoid and coolant fan relay. the fan relay and egr are the most common i see all the time. and with you having an isssue with that coolant light i want to say check the fan circuit.

let me know if you have more question thank you and good luck

Does it crank over?
