    C13 sometimes starts, somtimes not.

    Got electrical codes on all injectors.

    Looks like the injector driver in the ecm is starting to fail, do you have a test ecm to try?

    I tried other ECM, runs the same way, but I'm not sure other ECM is good too.

    Unfortunatly I cant install SiS on my computer now becouse I got no room on HDD and It would be nice someone post me wiring diagram) Thanx!

    about language, it is Russian, I live in Ukraine.

    Usually when you have fault codes for all 6 injectors at the same time, it's the injector drivers in the ECM as DDS said.

    Agreed.

    I had one throw me for a loop. I had a c12 throw all 6 injector faults, installed a known good test ecm, still threw all 6 still with the test ecm. My service manager told me to install a crank sensor and bam problem went away.
