Engine will not turn over after cold weather

Have your battery get load tested at a auto parts store the battery is rated by cca meaning cold crank amps. If the amperage is low it wont start

The 4.3 goes through distributor caps and rotors, try replacing those first. Its not so much the cold weather as it is wet weather.

check the cold start sensor and injector wires .take off and clean them.

With this new ethanol gas out now, folks may have to use ether again in cold weather. Good luck finding the air intake.

Sounds like you need to have your ecu repaired. I've seen this problem on 91-98 Grand Cherokees due to components inside the ecu slowly failing, and really acting up when the weather is colder. A good indicator as to if you have this problem is if your check engine light takes a while to light up, on the dash, when you turn the ignition on, before trying to crank the engine. If the light is delayed in your jeep, you need to repair the ecu.

Get your battery voltage checked.The cold weather will reduce the strength of your battery. The starter solenoid is trying to engage the starter but it doesn't have enough power from the battery to make it happen.If the battery voltage is low then get it recharged .The voltage of fully charged battery will show near to 12 volts.--------------That's it.

I am assuming this a cold weather only issue ?? Turn your key to on before cranking it over for about 5 sec to let the glow plug heat up a moment. Not allowing the glow plug to warm will wear out your starter.

These engines require a LOT of amperage from the battery. A battery's amperage output is severely decreased in the cold weather. If your battery is old, it may not have the power to turn the engine over. Your solutions are (1) warm the engine to allow for easier turn-over and (2) put a charger on the battery to keep it warm in cold weather. The first can be accomplished by having your dealer install a soft-plug block heater. As to charging the battery, be sure the charger is one that monitors the battery's charge and turns itself off when the battery is fully charged.
If this does not help, then your cold cranking may have caused your starter to begin to fail. Good Luck and stay warm!
