Hello, I am having an issue after fuel filter was changed and some fuel line work (I am DIYer). I have followed the instruction of bleeding the air from the fuel line. The issue is the jeep is cranking but will not start and there are 2 codes:
P0091 - Fuel Pressure Regulator 1 Control Circuit Low
P0003 - Fuel Volume Regulator Control Circuit Low
Looks like the fuel pressure sensor or a ground.
I have searched this forum, Googled the codes and checked the service manual. There are 5 things I need to look at:
• Faulty fuel pump
• Faulty fuel pump relay
• Faulty PCM
• Faulty electric fuel pressure regulator
• Restriction in the fuel filter or other parts of the fuel system
• Damaged wiring such as a short to ground
• Fuel tank low on fuel
I thought I would check with the forum to see if there is any thing else?
