P0087 - FUEL RAIL PRESSURE TOO LOW Possible Causes: - Fuel pump module failure (low flow due to faulty tank lift pump or wiring) - External fuel leaks - Clogged fuel filter - High-pressure pump malfunction - Injector leakage - Faulty fuel pressure limiting valve This code indicates insufficient fuel rail pressure, which can lead to poor engine performance or stalling. Start with checking for external leaks and ensure the fuel filter has been replaced. If no leaks are present, inspect the fuel pressure limiting valve as a next step.

Thanks for the detailed explanation! I've already ruled out any visible fuel leaks and recently replaced the fuel filter. My next step is to replace the fuel pressure limiting valve. I'll update this thread once I have results — currently stuck in the mud, but hopeful it's a simple fix.
