Question about 1995 Ford F350

Vehicle will not start 7.3 diesel

Took the vehicle to repair shop and they have replaced the high pressure oil pump (3 times) an the IPR valve.

When the vehicle would not start prior to have towed in I removed the fuel filter atop the engine and stuck my hand down in the diesel fuel and found a wire, pulled the wire and it seemd attached, gave it another small tug; it came out and had a connector on the end of it. It appear the other end had been soldered to the housing some way?

The repar shop is still getting diagonstic code indicating the high pressure oil pump and have replaced it three times. Could this wire be some type of sensor keeping the high pressue oil pump from working. Are you familar with the wiring in the fuel filter housing and what the wiring could be going to. Repair shop said they could not find a place for the wiring or where it would go. It is a repair shop that until recently only worked on diesels. I have been using them for years with good satisfaction......unfortunately they have had the truck for over a week now and three pumpls later I have a growing concern.

    Same problem, I was told to take the cover around the fuel filter then on the front of the housing take the set screw out and check to see if there is oil to the top, if not fill it up with oil. I guess it can loose the oil prime for the pump. Also I was told that there is a sensor on the front of the block that could be causing the not starting. Trying to find out what the sensor is for

Could be camshaft sensor, easy test, Crank engine over and watch the tach on the dash. If tach does not move engine will not start. Also I had Bad wiring for my fuel filter housing heater circuit. I found a cool website www.powerstroke.org. This site has tons of information on 7.3 in its forums. this is a free website although you may need to register. Hope this helps. I've been there.

I have a no start problem with my 1995 7.3L and checked the wiring connectors to the valve cover gaskets to the injectors. One of the terminals (out of five) is burned out on at least two connectors. I'll replace both gaskets and repair the connectors and let you know if that fixes it.

GWM Steed 2008 2.8 diesel turbo. The common fuel rail started leaking. It was fixed. When idle it did not leak but when refs up it started leaking again. Think could be due to too much pressure.


It should not over pressurize as there is a pressure relief valve on the pump I would take it back to the mechanic who repaired the vehicle and ensure when the common rail was replaced that all high pressure lines where also replaced

Replaced engine oil cooler and egr cooler on my 04 f350 6.0 I got in the truck and hit the throttle and it started to chok then died. new screen and seals on ipr valve and still nothing. Any ideas.


Check the high and low oil pressures. Low is normal pressure 30 to 80 PSI. If high pressure isn't at least 500 PSI. replace the IPR sensor.

Is this a diesel or gas vehicle ? and what engine does it have ? They all have different type of systems . Diesels have a low pressure and high pressure pump and IPC and IPR valves .

How much injector oil pressure should I have with just starter spinning over no crank and pours white smoke out exhaust


Here's you some info from a ford manual.
you can use any scan tool that will rear ICP pressure and RPM. you need at least 100 RPM while cranking.

Check oil level and quality first. if its low, it may not start, if it's old it may aerate easily(mix with air easily)

If the smoke is white/gray and smells like raw diesel, you possibly have a stuck open/Leaking Injector, Leaking injector O-Ring Seal. A failed glow plug system, can make white smoke as I am unsure of the cranking temp. if it is Blue/White there may be a compression ring issue.

A note on 7.3L injectors!!!! ALL of the Injectors are the same EXCEPT #8 (Last one on the Driver's side) It is a "Cackle" Injector. It looks the same but is slightly different. It even has a different part number in our Ford Catalog.

I hope that helps you let me know if you need anymore info.

Tools Required:
New Generation Star (NGS) Tester 007-00500 or equivalent

9c. Monitor ICP While Cranking (min 500 psi @100 RPM)
Purpose:
To determine if the injection control system can supply enough injection control pressure to sustain starting.
much-injector-oil-pressure-just-starter-ccu5ej1tcfbj3pe04s4es3xr-4-0.gif


Recommended Procedure:
Install NGS Tester. Access ICP and IPR PIDs on NGS Tester, and monitor PID readings while cranking the engine.
Note: CMP signal is required before IPR is commanded above 14%.
If ICP does not meet the minimum specification of 3450 kPa (500 psi), the injectors will not be enabled by the PCM because of insufficient rail pressure.
If IPR goes above 14%, ICP pressure should easily go above 3.4 MPa (500 psi) provided that the oil reservoir is full, the IPR valve is not stuck open, the high pressure pump is building pressure and there is not an injection control pressure leak between the high pressure pump and all of the injectors.
Possible Causes:
  • Injection control pressure system leak
  • Oil reservoir level low
  • IPR failure (sticking open)
  • Faulty high pressure pump
  • Injector O-ring leaking

What are codes p1249 & p1211


P1211 Injector Control Pressure Sensor Above / Below Desired P1249 Wastegate Control Valve Performance
P1211 We all know that this code is commonly caused by "Hot Chips" that are demanding more Injection Control Pressure (ICP) than the High Pressure Oil Pump can deliver. For what it's worth, these are the exact parameters that trigger this code:
  • ICP 410psi Higher Than Desired for 7 Seconds
  • ICP 280psi Lower Than Desired for 7 Seconds
This code can also be caused by legitimate High Pressure Oil System issues. Below is a list of some of the causes:
  • Failed or Sticking IPR (Injection Pressure Regulator)
  • Failed or Weak HPOP (High Pressure Oil Pump)
  • Any Leak in High Pressure Oil System (o-ring, stuck injector, etc.)
  • Low Fuel Pressure (Rare)

P1249 it is the HPOP, above or below pressure, if you have added a performance chip to your vehicle , you will get this code from time to time, basically its Turbo over boost

P1209 code and no start


DTC P1209 indicates that injection control pressure was above or below desired level under normal driving conditions.

Possible causes:

  1. Incorrect oil or viscosity
  2. Poor oil quality
  3. Gel fuel/no fuel
  4. Low fuel pressure
  5. Damaged IPR valve
  6. High-pressure oil system leak
  7. Damaged high-pressure oil pump
  8. Damaged PCM
  9. Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.

WHERE IS THE IPR LOCATED ON THE ENGINE ?


The "IPR" is and Injector Pressure Regulator. It is a Solenoid used to control the oil pressure created by the High Pressure Oil Pump. The IPR is capable of regulating oil pressure from 0 to 5000 psi. On an 05 6.0l the IPR is located in rear, top, center of the engine in the High pressure oil pump. It can be identified by its gold color. It sticks out of the side of the pump pointing toward the driver side of the truck. It has a 2 wire plug that is held on by a metal clip. usually the ipr and plug are protected in a heat shield so you may not be able to see it right away. Some people mistake and IPR for and ICP. The ICP is a sensor that tells the PCM what the High oil pressure is. ICP stands for Injector Control Pressure. This sensor is located in the passenger side valve cover on and 04, 05 6.0l and in the top of the High pressure oil pump on an 03 6.0l.
