The turbo diesel in your Isuzu Trooper is preferred by some drivers because of the fuel economy. If you are having problems with the turbo diesel engine, there are a few things that you can do before you take it in for service. You can check common issues yourself with little hassle.
Turn the key in your Trooper's ignition to engage the instrument panel. Make a note of the fuel gauge's level. If you don't have enough gas to start the Trooper, fill the tank up with gas and then try to start the vehicle.
Replace the fuel with the proper kind of diesel. Summer diesel can get cloudy in winter months. This can cause the fuel filter to clog.
Raise the Trooper with a jack to check the starter. Have a friend turn the ignition and listen for the starter to buzz. The starter is the small black box next to the engine. If the starter buzzes or clicks, you need to have it replaced by a service technician.
Look at the bottom of your Trooper for any fuel or liquid leaks. Have any leaks checked by a certified mechanic.
Use a voltmeter to test the battery. Check the battery sticker to get the volt rating. Most diesel engines use a 6.5 V battery. Connect the leads from the voltmeter to the battery terminals on the top of the battery. If you don't get the 6.5 V reading, have the battery replaced or jump the car.
