Hello, sounds like an issue with a loss of fuel pressure. A diagnostic check for codes with a scan tool should be one to see if any lean codes or fuel pressure fault codes are stored. If so it would have to be driven with a fuel pressure gauge to verify if the fuel pressure is dropping and monitoring the fuel rail pressure sensor to see if it matches the actual pressure reading. If it is a fuel pressure loss, it uses a pickup up pump and main pump on both sides of the tank. If the vehicle sits for long periods of time, the fuel pump sock filters can deteriorate and plug the pump. both pumps should be changed at the same time with the fuel filter.
Hello, do you need more help with this concern?
