Q: Jeep won't start. One click when key is turned.

asked by on

Out of no where my jeep would not start. It was running for about 20 minutes. I parked. 10 minutes later went to start it all all I got was one click when the key turned. I get power to my lights, radio etc. Tried jump starting it. Brought my battery, which was fully charged and eliminates the alternator problem, to get tested and it was good. Pulled my started to get it tested and it was good. Now I'm not sure where to go from here.

My car has 130000 miles.
My car has an automatic transmission.

Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the immobilizer system is on, you may see a security warning light. To temporarily override the immobilizer system, see these instructions. If there is no starter motor operation at all, that is if there is no starter operation with the key held in the "start" position, the procedure is to test for power to the starter motor. If there is no power, then the electrical circuit supplying the motor has a fault. That circuit begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. Basically, with a fully charged battery, and with the key held in the "start" position, the starter is either getting power or it isn’t. With the key in the "start" position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. Note that starters can and do sometimes develop intermittent faults due to bad spots on the armature. The bottom line is if there is battery voltage to the starter (and no excessive voltage drop) and yet the starter doesn’t work, it’s dead. If you desire that a certified mechanic resolve this, please request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you.
