1. Incorrect Distributor Installation: Ensure that the distributor is seated correctly and the timing is accurate. The rotor should align with the notch on the distributor cap when the engine is at top dead center (TDC) of the compression stroke.
2. Distributor Cap and Rotor Issues: Inspect the distributor cap and rotor for cracks, carbon tracking, or corrosion. Replace them if necessary. Ensure the spark plug wires are connected properly and in the correct firing order.
3. Fuel System: Check the fuel pressure and ensure the fuel injectors are functioning properly. If the fuel pump is not working or there is a blockage in the fuel lines, the engine will not receive enough fuel to start.
4. Spark Plugs: Verify that the spark plugs are in good condition, properly gapped, and seated tightly. Faulty spark plugs or incorrect gap can prevent the engine from starting.
5. Ignition Module: The ignition module, also known as the ignition control module (ICM), is responsible for controlling the spark timing. A faulty ignition module can lead to ignition system malfunctions and prevent the engine from starting.
6. Timing Belt: If your Acura Integra has a timing belt, ensure it is in good condition and not damaged or misaligned. A broken or incorrectly tensioned timing belt can cause timing issues and prevent the engine from starting.
7. Immobilizer System: Check for any issues with the immobilizer system, which prevents unauthorized engine starts. If the immobilizer system is not functioning properly, it can prevent the engine from starting even with a correctly installed distributor.
If you have checked all of these components and the engine still does not start, it's advisable to consult with a qualified mechanic or automotive technician. They can diagnose the exact cause of the problem and provide the necessary repairs to get your Acura Integra running again.
