Diagnosis of the injector with their own hands

Even some ten years ago it was almost impossible to find a service support vehicles, equipped with apparatus for the qualitative diagnosis of the injectors. Many drivers have a problem related to poor work organization injection system, go to authorized dealers. For the owner of service stations snag was that for the qualitative diagnosis of the injector equipment then, and now, in principle, is not cheap. And if a start because he needed to spend a lot at once, and the level of recovery was illusory unity, by the way, and experienced professionals, diagnosticians in those days was a little on such costs were not all. Nowadays the situation has changed dramatically. Many services gradually began to lose their permanent customers, because they do not have the opportunity to competently serve car equipped with fuel-injected engine. Along with this, there was still some factors that pushed to invest in new equipment business: 1) gradually increased income middle class population. A growing number of people have been able to afford to buy a foreign car, even if second hand, that the overwhelming number, have long, available with fuel-injected engine, 2) Virtually all Russian manufacturers have switched to the production of cars equipped with an air injection system. Of course the quality of produced cars, remains at a low level. And in consequence, the periodic damage arising from a visit to service stations, and 3) The cost for diagnostic computer equipment, followed by increasing competition, began to decline, albeit slowly. Earlier, the price for a complete set $ 28-34 thousand. Today, the emergence of domestic and Asian manufacturers, you can buy the initial kit for only $ 6,000. Naturally enough, and this, because to fully complete diagnostic center requires large investments. But for the start of business, and this is quite enough. However, to conduct such diagnostic procedures can be their own. For those who are used around the deal itself and wants and tries to cope with the problems of the injector, was developed by a small manual for diagnosing fuel injection engine problems: 1) If the starter is scrolled, and the motor will not start: A) You need to check, did not sit down Does the battery. If the charge was over, the problem is found, and b) If still the battery is in order, check-availability of fuel in the fuel tank - fuel pump work - performance ignition - the sensor in the crankshaft, and 2) If a bad start the engine: A) It is worth believe the air filter is not clogged it, b) Check the temperature sensor - not whether he is lying more than 5 degrees C) You can check the index of the throttle valve sensor (when pedal is released to 0%, while holding 100%); F) Also check the sensor crankshaft; D) You can check the ignition, and E) Check the fuel pump work, W) should see all contacts. It is worth noting that this is a universal indicator of failure of all systems, with verification of contacts should start looking for any problems. B) Test whether the nozzle; If nothing can help, should check for overheating fan cooling system for contamination - air filter on the performance - the sensor phase. There are cases when not helping either one of these items. In this case, of course, you should contact a qualified service for qualified help.
