Most Reported On
P00C6 is an OBD-II diagnostic trouble code meaning “Fuel Rail Pressure Too Low - Engine Cranking.” On direct-injection engines the PCM monitors high-pressure fuel-rail pressure during cranking. This code sets when the rail fails to reach the pressure required to start the engine, which usually results in extended cranking, hard starting, or a no-start. This code is most commonly reported on 2023-2024 Chevrolet Equinox (LS, LT, RS, Premier), with repair costs ranging from $1,000 to $1,200.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
