If your car will not start, don’t panic, it’s not end of the world, confuse what should you do? Diagnosing a condition takes a logical way of figuring out what may be preventing your car engine crank and running. Below is a list of causes that could prevent your car to start.
When you turn the ignition key to start your car, or press the START button, then voltage from the battery flows through the ignition switch to the Park/Neutral safety switch or brake pedal or clutch pedal security switch (you must push down the pedal before the circuit will finish) to the starter relay or solenoid. The motor spins, pushes the drive gear to engage the flywheel and cranks the engine.
If the engine fails to crank, there’s a fault in one of the elements from the battery/ignition/starter circuit.
GENERAL CAUSE ENGINE WON’T START OR CRANK
Check the battery voltage, and recharge the battery if low, or jump start along with a battery charger or different car.
Bad starter relay/solenoid
Check for voltage in relay, if relay has voltage but there’s no “click” when key is turned to start, replace relay.
Jump battery voltage guide to starter to see if it spins, or eliminate starter and possess it bench tested at auto parts store.
Damaged drive on flywheel or starter teeth
Inspect flywheel teeth and drive gear after starter has been removed, if you found a broken parts, just replace it.
Poor ignition switch
Check to determine if voltage reaches starter solenoid/relay when turn to get started. Otherwise, check for switch and clutch or brake pedal switch.
Clutch Pedal (manual transmission) or Brake Brake Pedal Safety Switch (automatic transmission)
Bypass switch to find out if engine cranks, or utilize test light or voltmeter to test for voltage passing through change when ignition is turned to start.
Smart Key Fob Battery Dead
For starting procedure (emergency), please refer to your owners manual for dead Smart Key Fob battery when your vehicle won’t be started by your Key fob. On certain vehicles, setting the fob near the push start button, pushing the Start button using the fob, or placing the fob within a steering column, special slot within the instrument panel or centre console may let it communicate with the ignition system so that your engine will crank and start.
Engine captured due to internal damage or bearing failure
Use socket along with long handle to find out if engine could be switched by hand, if not it’s mean the engine is locked up.
Engine hydro-locked because of coolant leak from leaky head gasket
Use wrench and socket to find out whether engine melts, remove spark plugs and see if coolant comes out or engine can’t be cranked with plugs out.
ISSUE: ENGINE WON’T START BUT IT CRANK
If the engine cranks over once you try to start you car, but the engine doesn’t start, the issue might not be any FUEL, NO SPARK or NO COMPRESSION. To get started, the engine needs adequate fuel pressure.
