CUSTOMER CONCERN The engine cranks but will not start and stores DTCs P3190 and P0A0F. CAUSE The in-tank fuel pump failed; multiple confirmed repairs on the same hybrid application restored starting after fuel-pump replacement. CORRECTION Remove and replace the failed fuel pump, clear DTCs P3190 and P0A0F, and verify engine starting, fuel pressure, and hybrid-system operation.

CUSTOMER CONCERN After diesel fuel was mistakenly added, the engine only cranks or runs briefly and DTCs P0A0F, P3190 and P3191 are stored. CAUSE Diesel fuel remained in the gasoline fuel lines and prevented normal combustion. CORRECTION Drain the contaminated fuel, flush the fuel tank and lines, refill with gasoline, clear P0A0F, P3190 and P3191, and verify the engine starts and runs normally.

CUSTOMER CONCERN The engine has low power, and DTCs P0A0F and P3190 are stored. CAUSE Fuel-pressure testing showed pressure dropping under load even though battery voltage remained available to the fuel pump on the gray supply wire, confirming a failed fuel pump. CORRECTION Remove and replace the failed fuel pump.
