What is the 2000-2005 Pontiac Montana Fuel Pump / Fuel System Failure Causing Stalling and No-Start?
Montanas frequently develop fuel-delivery problems: in-tank fuel pump failure and clogged fuel filters cause hard starting, long crank times, intermittent stalling, and no-start conditions. A common pattern is the engine stalling when hot and restarting only after it cools, due t… Repairs typically run $400-$800. Severity: high.
