Q: fuel volume regulstorcontrol circuit /open

asked by on

no power run ruff

My car has 101000 miles.

Hi there. The fuel pressure volume regulator control circuit/open requires circuit test be performed. A scanner would help for monitoring the parameter. The fuel pump could be at fault, with little or no fuel pressure, the PCM (powertrain control module) might recognize this as a control circuit issue. No power and runs rough, leads me to think, a fuel pressure test is in order. I recommend having your vehicle’s no power and runs rough be diagnosed and repaired by a certified technician from YourMechanic.
