Q: The engine stutters for a while before starting. 2002 Honda Civic

asked by on

Whenever I insert the car key the engine stutters and rumbles before starting and it takes a while.
My car has an automatic transmission.

Hi there - if your car stutter-starts, but runs fine once it is running, you probably have a problem with the fuel system check valve. This valve maintains some fuel pressure in the system so that your car starts faster once the key is turned to "Start". A malfunctioning check valve requires the fuel pump to run longer to build adequate pressure for the engine to run, resulting in longer cranking time, and stuttering as you describe. I would recommend a fuel system inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
