Engine unable to start but cranks

If the fuel pump is not delivering adequate fuel pressure and volume to the engine, the engine may not start or run properly. Low fuel pressure can cause hard starting, a rough idle, misfiring, hesitation and stalling. No fuel pressure will prevent the engine from starting, or will cause the engine to quit running if the fuel pump fails while driving. Fuel injected engines are very sensitive to fuel pressure as well as fuel volume. Low pressure will cause starting and driveability problems. A pump that can deliver adequate pressure but not enough volume may allow the engine to start and idle normally, but it will starve the engine for fuel and cause a loss of power when the engine is under load, accelerating hard or cruising at highway speeds. Engine Cranks But Will Not Start A dead fuel pump can prevent an engine from starting, but so can a problem with the ignition system or the engine itself (such as a broken timing belt). The first thing to check would be spark. This can

Black smoke of an engine

It is not uncommon that petrol engine exhaust black smoke, following poor fuel economy. This is due to an incomplete combustion in the chamber. If the supply of air (Oxygen) is insufficient, compared to fuel supply, it causes incomplete burning of the available fuel, and excess fuel exhausted, which causes blacky smoke of the engine, alot of fuel wasted. Parts of the engine that causes this Airflow sensor (airflow meter) Air cleaner element, if it's clogged with dust particles Blockages of injector holes Faulty oxygen sensor Absence of fuel pump pressure regulator Remedies Replace the airflow sensor if tested faulty, the common test for this is by racing the engine and noticing that the accelerometer pointer will be seen not passing 3000rpm and engine would be frustrating Dust the air cleaner element or replace it, if possible Use carb cleaner or thinner and free all the holes of the injector Clean or replace oxygen sensor, this is mostly notice by the engine

Steam Cleaning of your car's engine.

There are lots of debates about steam cleaning of an engine, as in whether it's necessary part of an engine maintenance or not. As an engineer and instructor I always answer it as the necessary but not the compulsory part of engine maintenance. I therefore implore my clients to read and know the advantages and drawbacks of this: Safety Steam cleaning  significantly reduces the incidence of accidents that engine fire brings about. Longevity It can extend the overall life of the car engine. A clean and well-maintained engine is safe from rusting and clogging which may affect and reduce the performance and longevity of an engine. Early Detection Through this process, you can identify the source of any type of fluid leaks. Most engine fires are attributed to unidentified leaks which early detection could have prevented. But how could you detect the leaks if mud and grime cover the engine? Beauty It can improve the engine’s appearance and increase its resale value.
