Town and country fuel rail regulator

Your van has the regulator integrated into the pump module (aka pump assembly). The factor repair information shows that it is serviceable separately from the module. However, there are many potential causes for your concern. So, before jumping to conclusions and replacing the regulator, I recommend getting a professional diagnosis of your vehicle.

Have you performed testing with a diagnostic tool that is showing component operation and performance as it is happening? How is your test procedure being performed to validate your findings?
