I quickly drove to the grocery store and 10 minutes later returned to the parking lot to drive home and the car would not start. I attempted to jumpstart it as well as fluttering the gas pedal while it cranked. Only once did it ever begin to even fire but died seconds later with a P228D code generated, I suspect sense it did not run correctly all kinds of errors were going on and that maybe simply a symptom.



Steps taken:
(fuses) checked all fuses
(battery)Battery has 12.4VDC
(fuel)Low pressure side of fuel pump 66 PSI, replaced fuel pump
(spark)Pulled a spark plug and coil and confirmed spark during cranking, although it needs new spark plugs it was running minutes before
(air)Cleaned MAF, replaced MAF
(crankshaft position) replaced crankshaft position sensor

I have attached a screen shot of my OBDII scanner information during cranking.

Some looking has shown there also exists a timing chain defect possibility; two more sensors on the fuel rail itself; injectors; ECM

I am unsure what my next steps should be. Please advise.

Probably time to bring it to a trusted mechanic, or the dealer ???

Just fyi the truck will not run or throw codes for the high pressure fuel rail pressure sensor. It should still at least. Start.... With these di motors they won't start w a fuel pressure fault.idk why but unless u have the pressurized fuel system running it won't run.its at like 450psi

DTC P0089, P00C6, P053F, P228C, or P228D
Diagnostic Instructions
DTC DescriptorsDTC P0089
Fuel Pressure Regulator Performance
DTC P00C6
Fuel Rail Pressure Low During Engine Cranking
DTC P228C
Fuel Pressure Regulator Control Performance - Low Pressure
DTC P228D
Fuel Pressure Regulator Control Performance - High Pressure
Circuit/System Description
The high fuel pressure necessary for direct injection is supplied by the high pressure fuel pump. The high pressure fuel pump is mounted on the rear of the engine and is driven by a three-lobe cam on the intake camshaft. This high pressure fuel pump also regulates the fuel pressure using an actuator in the form of an internal solenoid-controlled valve. In order to keep the engine running efficiently under all operating conditions, the engine control module (ECM) requests pressure ranging from 2 to 15 MPa (290 to 2,176 psi), depending on engine speed and load. Output drivers in the ECM provide the pump control circuit with a 12 V pulse-width modulated (PWM) signal, which regulates fuel pressure by closing and opening the control valve at specific times during pump strokes. This effectively regulates the portion of each pump stroke that is delivered to the fuel rail. When the control solenoid is NOT powered, the pump operates at maximum flow rate. In the event of pump control failure, the high pressure system is protected by a relief valve in the pump that prevents the pressure from exceeding 17.5 MPa (2,538 psi).
The fuel rail pressure sensor provides the feedback necessary to the ECM to control the high pressure fuel pump and the fuel injectors. This sensor is diagnosed separately from the fuel pressure control system.
The ECM monitors the fuel rail pressure sensor and the high pressure fuel pump actuator to determine if the commanded and actual pressures are within a predetermined range during engine cranking and at all times while the engine is running. The ECM also monitors the fuel pump actuator to make sure it is operating within expected limits.
Conditions for Running the DTCP0089, P228C, or P228D
  • DTC P0016, P0017, P0090, P0091, P0092, P00C8, P00C9, P00CA, P0112, P0113, P0116, P0117, P0118, P0128, P0192, P0193, P0335, P0336, P0340, P0341, P0365, P0366, P0627, P0628, P0629 or P1682 is not set.
  • The ignition voltage is greater than 8 V.
  • The engine is running.
  • The low side fuel pressure is greater than 275 kPa (40 psi).
  • The DTCs run continuously when the above conditions are met for 60 s.
P00C6
  • DTC P0016, P0017, P0090, P0091, P0092, P00C8, P00C9, P00CA, P0112, P0113, P0116, P0117, P0118, P0128, P0192, P0193, P0335, P0336, P0340, P0341, P0365, P0366, P0627, P0628, P0629 or P1682 is not set.
  • The ignition voltage is greater than 8 V.
  • The engine coolant temperature is less than 65°C (149°F).
  • The low side fuel pressure is greater than 300 kPa (43.5 psi).
  • The diagnostic runs once for each engine start.
Conditions for Setting the DTC
P0089
The high pressure fuel pump has exceeded it's control limits. This condition exists when the high pressure fuel pump actuator command is 0° or greater than 240°. The condition exists for greater than 10 s.

P00C6
The ECM detects that the fuel rail pressure is not rising greater than 3 MPa (435 psi) or has fallen below 2 MPa (290 psi) during engine cranking, depending on initial pressure when cranking begins.

P228C
The actual fuel rail pressure is 3 MPa (435 psi) less than the desired fuel rail pressure. The condition exists for greater than 10 s.

P228D
The actual fuel rail pressure is 3 MPa (435 psi) greater than the desired fuel rail pressure. The condition exists for greater than 10 s.

Action Taken When the DTC Sets
  • DTCs P0089 and P00C6 are Type B DTCs.
  • DTCs P228C and P228D are Type A DTCs.
  • A message center or an indicator displays Reduced Engine Power.
  • Scan tool control of the high pressure fuel pump is inhibited.
Conditions for Clearing the DTC
  • DTCs P0089 and P00C6 are Type B DTCs.
  • DTCs P228C and P228D are Type A DTCs.
Diagnostic Aids
  • Any problem with the camshaft may set fuel pressure DTCs due to the location and design of the high pressure fuel pump. If camshaft position control DTCs are current or in history, a cam control issue may be the root cause.
  • A faulty valve, plunger, or solenoid in the high pressure fuel pump may set a DTC. High pressure fuel pump damage will most likely be undetectable upon visual inspection.
  • A restricted fuel feed pipe between the fuel feed pipe fuel pressure sensor and the high pressure fuel pump may set a DTC.
  • A leaking or restricted fuel injector may set a DTC.
  • A leak in the high pressure fuel system may set a DTC.
  • Vapor lock may set DTC P0089

Thank you for this information. All of these components are working correctly. The High pressure fuel pump and high pressure fuel sensor have been replaced. Still the vehicle does not start.

So you have fuel and spark but still not starting?
That is correct. 2000 psi fuel in fuel rail, pulled a coil and plug and tested for spark, it's a weak spark but still a spark, MAF sensor is working and registers 1-2 g/s during cranking

I pulled two plugs and coils and got a short video of them during cranking. They are both what I would describe as a very weak spark.

If that is the issue how did the engine run and then not run 10 minutes later? What effects all 4 coils and plugs?

I didn't see from your posts but did you do a compression check?
What were the numbers.

Thats probably going to be a battery issue. Could u test it for cranking amps? Yea it's at 12.4 but if it drops below 10.5 while starting it just won't. Check the ground wire on the back right of the motor on the valve cover. If u wanted to check out the timing chain pop off the valve cover get a bright flashlight and look down at the guides can be done pretty easy.

At 2k psi u will blow something u need to relieve that pressure or it won't start no injectors will fire either ur close to blowing the steel line-fuel rail and high pressure fuel pump...fireball

70 psi before fuel pump
1500 after on the fuel rail

That is a brand new fuel pump and fuel rail sensor. Why is the pressure so high?
