Why is My Car Not Starting?

Let’s narrow it down.  There are two scenarios to this question. Scenario 1 is when the engine cranks over but will not start up and run. This is when you turn the ignition key and hear the engine turning over but it will not crank up and run on its own.  Scenario 2 is when you turn the ignition key, and nothing happens.  Everything is still.  The engine does not crank over at all.

Scenario 1:  The Engine Cranks but will not fire up and run.  If this occurs, the Ignition Signal, the Battery, and the Starter are all working fine.  This problem is more complex.  The Starting System is ok, but the engine is not getting proper fuel or ignition to keep it running.  For the engine to crank up and begin running, combustion must occur. Combustion happens when fuel mixes with air, and ignition spark from the spark plugs ignites the mixture.  The Onboard Computer controls this.  When the computer is ready to run the engine, it sends a signal to the Fuel Injectors to pump fuel into the motor.  It also sends the signal to the Ignition Coils to fire the spark.  Now the engine will run.  To Trouble Shoot this, a Mechanic will need Computer Test Equipment, Pressure Gauges, and Volt Meters. Because of the time involved, this can get expensive.

Scenario 2:  The engine will not crank over.  Nothing happens when the key is turned.  This is a cranking problem.  This fix is easier than Scenario 1.  The Mechanic will begin by testing the Battery Voltage.  If the Battery tests good, then the next step is Testing to see if the signal from the Ignition Switch is present.  If so, then the next step is Testing the Starter Motor.  One of those three components will usually be the cause for the engine not starting.  If those three items are all ok, then the final step is to get deep into an issue with the wiring harness. Trouble Shooting this problem is allot easier and less expensive.
