Hello,
I'm having a big problem. I manage to read some code. So I have P0251, P0191, P2291, P0340, P0190, P1211... HORRIBLE. But I have fuel up to injectors, I have try to do leak off test while cranking but no fuel come back from injectors. According the reader i have about 3900-5000 psi of fuel pressure. i have check IMV it has 5.3 ohms which is ok. Can anyone help? Why I do have fuel but injectors are not opening and no fuel is coming back? Also I check injectors all of them is around 0.3 ohm.

 

Welcome to the forum Aurimas,

If you had posted an Intro as we ask all new members, there could have been some faster progress with this issue.

Here are the possible causes for the DTC's you have found:




The two that stand out are P0191 and P0340. The first indicates a possible faulty Inlet Pressure Sensor (IP) and the second a possible faulty Camshaft Position Sensor (CMP).

The CMP is a Hall Effect sensor located on the front of the cylinder head and takes its signal from the inlet camshaft lobe. The signal is used to identify cylinder number three allowing the individual cylinders to be identified. If the CMP sensor fails, the engine will not start. This is the most likely cause of the non-start problem and the one I would check and eliminate first.

Hello,
Thank you for your answer. As I have describe in my previous post I have checked imv electrical part and it has 5.3Ohm. And I have fuel up to injectors and the pressure is in the range that the engine should be able to start. The most strange think was for me that when I was trying to do back leak test while crank the engine I had no diesel at all coming back. No I have order new cam shaft sensor and we will see where we going to go.

Regards

 

So I have replace cam sensor still the same... Please see the picture this is fuel pressure when cranking engine. Any ideas?

 

And now I have u2511 code. Could it be imobiliser issue?

 

Have you solved this problem yet? It could be a bad injector causing all of them not to start, usually if one injector is completely gone/broken it prevents the car from starting.
