P00C6 on Chevrolet
Fuel Rail Pressure Too Low - Engine Cranking
P00C6 on Chevrolet vehicles indicates fuel rail pressure too low - engine cranking. Au7o has documented this code across 1 Chevrolet model — most commonly on Equinox. 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. Typical repair costs on Chevrolet range from $1,000 to $1,200, depending on the specific model and root cause.
Common Causes of P00C6
- •Weak or failing low-pressure (lift) fuel pump
- •Failing high-pressure fuel pump
- •Leaking or stuck fuel injector
- •Clogged fuel filter or restricted supply
- •Faulty fuel rail pressure sensor
- •Very low fuel level

Chevrolet Equinox(1 issue)
- High-Pressure Direct-Injection Fuel Pump Failure Causing Stalling and Limp Mode (1.5L Turbo)2023-2024
Owners of 2023-2024 Equinox models with the 1.5L turbo (LYX) report the engine-mounted high-pressure direct-injection fuel pump failing, often well under 60,000 miles (some as early as 28,000 miles). The pump can no longer maintain rail pressure, so the engine suddenly loses power, drops into 'Engine Power Reduced' limp mode (speed limited to roughly 5-55 mph), stalls, or won't restart, frequently leaving the vehicle undrivable and requiring a tow. CarComplaints logged 20 distinct 2023 fuel/propulsion complaints centered on this part, and many owners report the replacement pump being on national back-order for months. This is a separate failure from the earlier 2021-2022 in-tank low-pressure fuel pump module recall.
