Many times in the past as an automotive engineer, I would diagnose a car or had a problem that the car the engine prevented the car from falling over or the engine is started to prevent be given. These are two completely different scenarios and these problems are resolved in a different way. Sometimes, if the writer would create a service work order, would not convey the real problem is that the customer experience. If the customer or make sure the service writer wouldthe correct explanation of the problem is written, it would avoid some unnecessary trips to the car with the wrong tools. For example, if the machine does not run more than anything else, I would take my box to jump with me. And when the car is cranked, but not starting, I want my tool of analysis and start some fluids.
A machine that most eccentric, but not started, in many cases due to a faulty fuel pump, a broken timing belt, cam crank sensor or a sensor ineffective. The first step inThe diagnosis of departure is to scan for codes with a code reader or scan tool. About 40% of the cars that I have worked over the past 25 years, had read or a bad fuel pump or fuel gauge wrong and the car was towed to the only fuel. Yes, some people actually have in their cars when all they need is a little 'gas towed! If the fuel gauge indicates the fuel in the tank, most people assume, of course, assumes that the car consumes fuel. But when the fuel unit is transmitting or DMSa little ', the car may actually be empty tank. One of the easiest ways is to check for a problem related to the fuel pump to spray a little 'liquid from the air intake while trying to start the vehicle. If the car starts to short, then it is a good chance the fuel pump is not working or the car is gasoline. You can also apply to the hum of the fuel pump sound when the key is turned on for the first time. Even if a fuel pump ineffective is suspected, a good technician always checkscontrol, there are power and ground is supplied with the pump in order to eliminate the possibility of a defective relay or electrical problem. Fuel pressure can be controlled with a pressure gauge, and when there is pressure, pulse the injectors can in several aspects, including the most commonly controlled with the use of noid lights. If the injectors are not the wrist does not start the engine.

Broken timing belt also caused about 40% of the trailer after my experience. A broken timing belt can causethe car feels as if it were running out of fuel while driving. When you try to start the car while the engine is usually faster than normal through the engine with lower compression stroke is off and open the valves at the wrong time. If the timing belt could break, there is sometimes a code on vehicles ECU (Electronic Control Unit) can be set for a signal from the sensor cam. When this code is available, it is sometimes possible to see if the cam moves when the oilCap, while someone takes the starter. The rocker cover can be removed to allow greater access to the belt for inspection. Most of the time when a timing belt teeth (or wheels) are breaking the crank sprocket pulley under the belt prevents the camshaft to turn their backs.
The lack of momentum from the injectors, as mentioned above a car can not be exported. Which brings me to the third most common cause of a car that cranks out more, but starts around20% of the tow ins that I worked the following problem. Often the cause of the wrist is due to a bad cam or crank sensor. If your computer does not see either the crank or the cam rotates, the injectors will not be provided to pulse. A quick indication that a cam or crank sensor could be bad for RPM is to control the movement of the clock (if present) while attempting to start the engine. If you have an analysis tool is not just a code reader, the cam and crankshaft sensor data can bechecked on many vehicles entering the appropriate image. If no speed is displayed when you try to start the car, the respective sensor could be bad.
Obviously there are many brands of cars require different ignition and fuel delivery systems that a service manual to diagnose correctly or to learn more. But with the tips and tricks that I have over the years, you most likely causes of the event, which hopes to send in the right direction.
