It's role is to set the engine i. Once the engine starts and is in motion, the starter's job is complete.
If the starter goes bad, the engine will not crank properly or may not crank at all when you turn the ignition key on. If you hear a clicking noise when you try to start your vehicle, a broken or weakened starter could be the reason why your car isn't starting. This is very similar to the bad ignition switch example listed before. This makes it difficult for your car to burn the fuel it needs to get going.
II. If the Engine Stalls at Idle
Fuel filters should be changed every 15, to 20, kilometres, so consider swapping fuel filters next time you get your car serviced. You might feel a bit silly if this is the reason why your car isn't starting, but it happens more often than you may think!
When driving around all the time, it's sometimes easy to forget that your gas tank need to be refilled. The solution here is simple Hopefully you never experience the scenario where your car doesn't start, but if your car isn't starting and you need some assistance, one of our expert mobile mechanics will come to you to properly diagnose and assess the issue. Furthermore, a full car inspection will be included as part of this service. If our mechanic can't fix it on the spot, we will provide a cost and parts breakdown to you to ensure you understand what the problem is, how it will be fixed, and how much it will cost.
If you decide to move forward with the follow up repairs with us, the initial inspection becomes free and we will only charge you for the follow up repairs. In the world of today, this is a little harder, if not downright impossible.

With the advent of the electronic diesel fuel injection system, a scan tool and scan data will be your friend. The reason is simple. The pressure voltage, though, is always correct. If you are working on a common rail diesel fuel system, the injector rail pressure PID is the telltale PID on fuel pressure. All common rail engines have a pressure sensor in the high pressure rail. If this sensor is showing the proper amount of pressure, you can be assured there is pressure in the rail. There is nothing worse than working for an hour or so before finding out the fuel tank is full of gasoline or some other liquid that will not combust in the combustion chamber.
Once the proper compression and fuel pressure have been verified with a scan tool and the engine still will not start, the next step is to determine if the fuel is being injected into the combustion chamber. Over the years, I have seen many no start problems caused by stuck fuel injectors. This year alone, I have had three vehicles that needed a set of new injectors to resolve a no start problem.
A good way to verify fuel injection is to watch the tail pipe while the engine is being cranked. If fuel is being injected into the combustion chamber, some fuel will be blown out the tail pipe. Now, on vehicles with a catalytic converter and a Diesel Particulate Filter DPF this might not work, because the fuel vapor can get lost in all the exhaust components.
As a last resort, it might be a good thing to pull out a glow plug if the engine has glow plugs and give the engine a crank. If fuel is being injected into the combustion chamber, there will be a nice cloud of atomized fuel being blown out into the air. I am a little reluctant to grab a can of starting fluid and start spraying it into the air intake. Over the years, I have seen a few engines badly damaged from this quick start method. If the engine has the proper compression, the proper cranking speed and the proper amount of fuel injected at the proper time, the engine will start.
Before a technician can start on any diagnostic problem, he or she needs to be aware of how the system works. Back in the day, this was simple since there were only three different kinds of fuel systems, but today we have common rail, hydraulic unit electrical injector HEUI , some PLN systems and a few different versions of unit injection.
What to do if your CAR WON'T START
Before you start on a diagnostic problem, I would encourage you to get familiar with the fuel system and your scan tool. The bidirectional tests and controls from the scan tool will be where you do most of your testing and problem analysis. The problem vehicle in the bay is a Ford F Checking the VIN found it was powered by a 6. The odometer shows it has traveled 98, miles. The owner said the engine had died when rounding a left-hand corner, but the engine restarted and had been driven back to their business.
The next time the truck was needed, the engine would not start. Some GM cars, for example, had a problem with the security system sensor located at the ignition lock. Sometimes, the key just needs to be reprogrammed. In some older cars, there was a simple procedure to re-learn the key that would fix this problem. You can find the information how to re-program the key in your owner's manual or just Google it.
You also can try the spare key and if nothing works, your dealer is the place to call.

In most modern cars, only an authorized dealer can reprogram the key. Your dealer can also check the immobilizer system. If the "Check engine" light does not come with the ignition ON, it's possible that there is no power coming to the engine computer e. Read more: how to check a fuse. The starter won't crank If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine.
Most commonly this could be caused by a dead battery; here is How to check the battery. If the battery checks out OK, but the starter still won't crank, there could be a number of possible reasons. An ignition switch is an electrical switch installed at the back of the ignition lock mechanism. If jiggling the key in the ignition helps start the car, the ignition switch should be checked first. See this video. If a car doesn't start with the transmission in Park, but starts in Neutral, it could be caused by a problem with a neutral safety switch or the shifter cable.
For example, see this video. Read more about starting system. I can hear a click, but the starter won't crank It's a very common problem: you turn the key to the "Start" position, but the engine won't crank; all you hear is a single click or repeated clicking coming from the engine compartment. This has happened to me many times. Very often this could be caused by a weak battery or poor connection at the battery terminals. Sometimes a battery cable can get corroded inside causing the same problem. In some cases a bad connection between the negative battery cable and the engine bad ground can cause the same symptoms.
Of course, there could be other reasons, but most often this happens when there is not enough electric current for the starter motor to turn over the engine. See this paragraph: how to check the battery. Also, check the battery terminals to make sure they are not corroded. Here is a photo how a corroded battery terminal looks: Car maintenance checklist: Battery If the battery is OK and the battery terminals appear clean and not corroded, the starter solenoid, battery cables or the starter motor itself could be a problem. For example, a problem with the starter motor or solenoid is a fairly common cause for the Ford Taurus not to start.
Earlier models of this vehicle had some problems with starters too. A similar problem with the starter solenoid in Toyota Corolla sometimes can also cause a condition when there is a click but the starter won't crank. Similarly, in Toyota Camry a problem with the starter solenoid terminals could cause the condition where the starter would click, but would not crank. In either case the starter motor needs to be rebuilt. Read more here: Starter motor, starting system. The engine cranks very slow and won't start This also might be caused by weak or discharged battery; here is how to check the battery.
Diagnostic flowchart for a car that won't start or stalls
If the battery is OK, the battery cables could have a bad connection at the terminals or the starter motor itself could have a problem. Sometimes, the starter motor armature bushings wear out and the starter armature rubs against the field coils inside the starter motor; this will also cause the starter motor to crank very slow. If this is the case, the starter motor will need to be rebuilt or replaced. Another reason, the engine could have an internal mechanical problem e.
