Possible malfunctions of a running diesel engine (Mitsubishi Colt 4)

There are many faults that prevent the engine from starting, but many more faults cause it to run poorly. Again, don't assume. Use a methodical and systematic approach that will save time and money and increase the likelihood of detecting the fault.

It is also important to remember that the vast majority of faults are caused (for one or more reasons) by a lack of fuel in the injectors, so you should start by checking for fuel in the tank. This is especially important for those cars that can start on a flat surface, but will then run on an uneven road. Fuel leaks around the fuel tank may indicate leaks that can lead to air entering the fuel system and interruptions in the operation of the injection pump.

CAUTION: Before replacing expensive parts, check for any possible faults associated with less expensive parts or systems.
