Truck wont start again. It has new rail pressure sender and FCA regulator. My quadzilla says 9 psi lift pump pressure when i turn key forward. I just filled it up with diesel at station. Could it be bad fuel or plugged fuel filter? No codes or lights?

 

Had the same problem last Saturday. Dealer replaced the fuel pressure relief valve and all is well. Pump worked but couldn't build enough pressure because the valve was stuck open.

 

it started now. i drained a lil fuel out of the fuel canister petcock. Then purged it again and it started? water in fuel?
