2008 Kia Sorento 80,000 miles on it. Randomly, it has a crank no start problem. Otherwise it runs fine. The car also has a remote start.
The on-board capabilities of your Kia are pretty high. When problems occur, the computer often memorizes them. A lot of times, it will turn the engine on and have the Check Engine Light on and give you a code that way. But if it had stuff like a bad mode six or bad live data, and bad recorded data, a good mechanic will be able to analyze that. I’d start there if I were you because if it happens intermittently, it is something that you are going to need a computer to help figure the issue out. Otherwise, you are going to give it to somebody and say "drive it and find out what’s wrong," and this could take weeks, so you are going to pay them a lot of money. Find a professional mechanic to analyze that information and diagnose your starting issue first. That would be the best thing to do so that you don’t end up replacing any parts that are not faulty.
How to Identify and Fix Common car Problems ?

The battery may be too low to start the car, the ignition switch may have an open circuit for the start position, or the starter or starter relay may have failed. You may also have a bad fuse or two, so check those as well.
The most common reasons a Kia Sorento won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Cold temperatures affect the chemical process inside the battery and reduce its ability to hold a charge. It also thickens engine oil, increasing friction in the starter motor and forcing it to work harder.
If the car clicks when trying to start, but still won`t start, this can be caused by a weak battery, dirty battery terminals, a worn starter motor or a stuck solenoid. If might just need a jump start, but there are a few tricks to try before breaking out the jumper cables or electric jump starter.
Broken or Damaged Ignition
If your headlights can turn on, but your car won`t crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.
Broken Starter: If you`ve put your key in the ignition and hear a clicking noise when trying to turn the key then your starter has likely gone bad. Clogged Fuel Filter: If everything else in your vehicle feels fine but you`ve found yourself with trouble starting the car, you might have a clogged fuel filter.
Why Your Car Won`t Start When It`s Cold. When your engine cranks normally but doesn`t turn over, the problem could be traced back to the fuel system. That`s because gasoline has to vaporize before it can burn, and freezing (or below) temperatures make that difficult.
A difficult start could be due to a number of things, from a dying battery to a faulty starter. But if your vehicle has a hard time starting after sitting for just a few hours, it can cause an extra layer of confusion. When this happens, one of the most common causes is low fuel pressure.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Ignition timing on a no-start can be confusing, but it can still be tested by connecting a timing light, then watching the timing marks while an assistant cranks the engine. While this may or may not be base timing as specified by the manufacturer, it does let you know where the spark is occurring.
Starting a vehicle with a bad crankshaft sensor can be risky and it`s unlikely to work. Disconnect the damaged sensor and try spraying a little starter fluid in the throttle body on your engine. Then, try cranking the engine to start the vehicle.
If you continue having difficulties starting your car in the morning, you may have a drain on your battery somewhere, or you may need a new alternator.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down. The ignition system may be the coil, module, or pick up in the distributor.
The MAF can become clogged with excessive carbon build-up from the combustion cycle, or sometimes by road grime. If it is too dirty, it will be unable to correctly measure the air fuel ratio, and cause your car to not start or exhibit other unusual symptoms.
Despite above-average reliability ratings, many Kia models commonly suffer from engine failure and transmission problems. The most common Kia problems include engine failure, transmission problems, and faulty electrical systems.
Start the engine and, using the procedure described in section 20, listen to the cold start injector (located on the air intake chamber). You should hear a clicking noise, meaning the injector is functioning. If a clicking sound is heard, let the engine reach operating temperature and repeat the check.
The cold start injector is located on your engine`s intake manifold. When low engine temperatures are detected upon ignition, your car`s onboard computer will tell the cold start valve to inject more fuel into the engine. The increased combustion will allow your engine to heat up quickly.
