What are symptoms of failing or bad fuel control module??
Also what psi should your High pressure fuel pump be idle then rev then drop to minimum psi of? How would I know if low pressure fuel sensor is need to be replace or high pressure fuel sensor is the issue?? |

LPFP pressure should be around 72psi at idle.
HPFP should be around 700-ish at idle. When the LPFP EKP starts to fail the LPFP will shut off and kill the car, and then after the EKP cools down it will start working again.....or it might just die all together. |
