Hello there!
It sounds like you're dealing with a tricky no-start issue on your 2017 Jeep Patriot. Given the steps you've already taken, let's go through a few more checks to narrow down the problem.
1.) Fuel Delivery: You've replaced the fuel pump, but let's ensure fuel is actually reaching the engine. Check the fuel pressure at the fuel rail using a fuel pressure gauge. If the pressure is low or nonexistent, there might be a blockage in the fuel line or an issue with the fuel filter.
2.) Spark: You've checked the plugs and coils, which is good. Ensure that the spark plugs are actually sparking. Sometimes a visual inspection isn't enough, so use a spark tester to confirm.
3.) Air Intake: Make sure there are no blockages in the air intake system. A clogged air filter or a stuck throttle body can prevent the engine from getting enough air to start.
4.) Sensors: Faulty sensors can also cause these symptoms. The Crankshaft Position Sensor (CKP) and Camshaft Position Sensor (CMP) are critical for engine timing and can prevent the car from starting if they fail. A scan tool can check for any error codes that might indicate a sensor issue.
5.) ECM/PCM: The Engine Control Module (ECM) or Powertrain Control Module (PCM) might have a fault. If you have access to a scan tool, check for any trouble codes. Sometimes a simple reset can resolve electronic glitches, but persistent issues might require professional diagnosis.
6.) Immobilizer System: Ensure the key fob is functioning correctly. Sometimes, issues with the car's security system can prevent it from starting. Try using a spare key if you have one. Given the symptoms and what you've already done, I’d start by checking the fuel pressure and confirming that the spark is strong. If everything checks out but the car still won't start, it might be time to get a professional diagnostic to look deeper into the sensor readings and ECM/PCM functionality.
