1. Fuel pressure: Check the fuel pressure at the fuel rail to make sure it is within the specified range. If the fuel pressure is too low, the engine will not get enough fuel to start.
2. Fuel injector pulse: Check the fuel injector pulse at the fuel injectors to make sure they are receiving a signal. If the fuel injectors are not receiving a signal, they will not open and allow fuel to flow into the engine.
3. Spark plugs and wires: Check the spark plugs and wires to make sure they are in good condition and properly connected. If the spark plugs or wires are faulty, the engine will not be able to produce a spark to ignite the fuel mixture.
4. Air filter: Check the air filter to make sure it is clean and not blocked. If the air filter is blocked, the engine will not get enough air to start.
5. Throttle body: Check the throttle body to make sure it is clean and free of obstructions. If the throttle body is dirty or blocked, the engine will not be able to get enough air to start.
If you have checked all of the above and the engine still does not start, you may need to have it diagnosed by a qualified mechanic.
