Maintaining your grand Cherokee regularly will be able to eliminate the problems before starting. However, before you start troubleshooting, you have to make sure that you have just changed the oil and the transmission fluid. Also, make sure that you have flushed the radiator and added the new coolant. You also need to check the filter since it can keep the engine run properly. The following are some tips you can perform for troubleshooting your Grand Cherokee.
The first thing to do is to crank the engine and also check the cluster of the dash for the unusual reading. Search for the improper battery output, running temperature, and oil pressure readings. If the reading shows different result from the norm, it means that there is something wrong.
Then, regain the error code from the computer of your Jeep. Insert your ignition key and turn it on. Try not to crank the engine. Turn the key to the on and off position alternately and monitor the "check engine" or light for the flashing codes. Normally, the light flashes at a certain number of times for indicating the first number of the two-digit code and at certain time for indicating the second digit. Then, record the code to check the meaning on the owner's manual.
The next thing to do is to test the alternator and the battery for weak voltage. However, you have to make sure that the engine is cool. You can start it by attaching the volt meter to the negative and positive terminals. The tester will measure the voltage in your alternator and then consult the owner's manual to see the proper voltage output.
The next thing you should do is to check the disrepair by running the engine. If you note your Jeep malfunctions at certain speed, it points to a problem. Look for the broken belts, disconnected wires, and also broken or flattened hoses.
Then, check for the spark from the spark plugs. Detach the spark plug wires and crank the engine in a dark area like garage. Instead, you can also crank it during the evening to search for the spark arcing by using an arc. If it does not work, you can push the tester to spark plug. Then, test the engine. The flickering bulb indicates the spark plug is able to work properly.
The last thing to do is to check the pressure of the fuel. Attach fuel pressure gauge for testing the port in fuel rail. Then, crank your engine and watch the gauge face. To know the proper pressure for your Grand Cherokee, you can see on the owner's manual.
