Hi everyone,

Here is what I know.

Coming home from work I felt my truck shudder. I looked in the side mirror and see white smoke. I let off the accelerator and its goes away.

Now on the home stretch to my house the truck just dies. I put it in neutral, cost to the house, all the while trying to restart it. NO JOY!

The only code I get is "Low Fuel Pressure".

I replace the pressure sensor. Not cheap $280. NO JOY!

I replace the CP3 High Pressure Fuel Pump. Even more Not Cheap. NO JOY!

During the time I am trying to start the truck I notice fuel dripping out of the tail pipe just before the catalytic converter.

The last item I replaced before is the piping for the reticulation system. That's all the piping from the back of the Head and between the fuel filter and CP3 Pump. NO JOY!

I finally think maybe I have a mechanical problem, Cam, timing gear, something like that. So I shoot a little starting fluid in the breather. Runs just long enough to burn the starting fluid and that's it.

I hope this is enough information for you to at least point me in the right direction.

Important note: I have replaced all the injectors about 3 months. Not to say they are not the problem. Just covering all the bases.

Thank you for your time.

Lift pump?

 

I don't think so. When I crack the line to the fuel rail it sprays everywhere. I can hear the pump working.

Besides I have a dual fuel system with its own fuel lift pump and I think the odds of both lift pumps failing at the same is astronomical. Forgot to mention the duel tanks on my truck.

 

Cracking the lines won't tell what the pressure is. Need to put a high pressure gauge on it. How about injectors. Maybe one leaking or not working. BTW ether is not a good idea to start a diesel.

 

(: Yea, I know its not a good idea to put starting fluid in the diesel. I just had to know that it was not anything mechanical.

I just put the injectors in about 3 months ago so I am really hoping its not them. But it could be. Would one injector leaking let enough pressure out to keep the other from atomizing?

I guess I am going to have to invest in a High Pressure Gauge. This is the one tool I have been trying to avoid buying because you just don't use it that much.

Thanks.

 

Try AutoZone they may have a gauge you can borrow. If you can fins a shop you trust, have them do a injector leak down test.

 

Are you talking about the low fuel pressure side? Something around 14 psi, or are you talking about the high side around 22,000 psi?

 

High pressure side. You will need a high pressure gauge. You can check the low side as well.

 

The low pressure side is 12-14 psi. None of the auto parts store in Cleveland TN have a gauge set that I can rent that goes any where near the 23,206 psi the high side should make.

I will have to buy one. That will take me a few days to get one in.

Here is some new information. Some where during my starting and testing the truck the PCM has sent me some new code data. I am wondering if I have a bad PCM/ECU? Maybe a open circuit or bad ground?

I know about the cooling fan code. I disconnected it to see if I had a bad fan clutch.

Here is Data:
