Hello from egypt,
I have a citroen jumper/relay 2008 2.2 puma engine with injector pilot learning problem,
So recently i did engine rebuild and later i did buy rebuild kit for the injectors(nozzles and valves) from a china, i got a wokshop to do the rebuild for me and he tells me that the injectors on the test bench are ok,
But while trying to do the pilot injection learn via alfaobd and elm327 the process doesn't start at all and it gives sequence error i revised all the instructions for the process and still nowhere
Now i have error codes p1304, p1305 and p1306 ,for some reason i did try high pressure pump replacement function and it triggered the 1305 and 1306 ECs
The engine now is running in limp mode and doesn't show injectors correction values,
I tried to do the pilot learn with different launch devices with same result and also tried Multiecuscan always same result
Please can anyone help with this issue
