Car can't start

Try some starting fluid to see if it starts. This is to confirm it is fuel that is causing the problem.
Have you checked the fuel pressure?
Are there battery voltage at the injectors?
Was any repairs carried out prior to this occurring?

If your 1997 Suzuki Baleno fails to start despite replacing the fuel pump and confirming spark from the plug cables, there could be a few potential causes to consider:

Ignition Timing: Incorrect ignition timing can prevent the engine from starting. If the timing is off, the spark may not occur at the right moment for proper combustion. You may need to check and adjust the ignition timing to the manufacturer's specifications.

Timing Belt/Chain: If the timing belt or timing chain has slipped or is broken, it can cause a misalignment of the engine's internal components, leading to a no-start condition. Inspect the timing belt/chain to ensure it is in good condition and properly installed.

Engine Control Unit (ECU): The ECU, also known as the engine control module (ECM), plays a crucial role in controlling various engine functions, including fuel injection and ignition timing. A faulty or malfunctioning ECU could be preventing the engine from starting.

Regarding the timing diagram and spark plug part number, here's some information:

Timing Diagram: Unfortunately, I cannot provide specific timing diagrams without knowing the exact engine model in your Suzuki Baleno. The timing diagram is typically specific to the engine type and year. You should refer to the vehicle's service manual or consult a Suzuki dealership or qualified mechanic for the correct timing diagram.

Spark Plug Part Number: For a 1997 Suzuki Baleno with a four-cylinder engine, the correct spark plug part number should be specified in the vehicle's owner's manual or service manual. Alternatively, you can contact a Suzuki dealership or an auto parts store with your vehicle's information (year, make, model, and engine size), and they can provide you with the correct spark plug part number.

You need to check if the injectors are pulsing. A noid light across the injectors and cranking the engine would allow you to test the pulsing. If no pulsings are found, you could havea fault with the engine computer.
