cranks but no start and no fuel pressure in fuel line

Hey Jay, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Jeep is giving you some trouble. It's cranking but not starting, and there's no fuel pressure. Let's troubleshoot: 1. Fuel Pump Relay: Since replacing the fuel pump, ensure the relay is working. Swap it with a known good relay from another system. 2. Fuel Filter: Check if the fuel filter is clogged. If it is, replace it. 3. Wiring Issues: Inspect the fuel pump's wiring and connectors. Ensure there are no loose, frayed, or corroded connections. 4. ECM/PCM Issue: The engine control module might not signal the pump. Use a scan tool to check for any error codes indicating a problem. 5. Fuel Line Blockage: The fuel line might be blocked. Check for obstructions and clear them if necessary. If these steps don’t solve the issue, it might be time to consult a professional mechanic. Good luck!
