    Default Fuel System Monitor will not Ready

    Like said, this car will not ready the fuel system monitor. (incomplete)

    Fuel trims are +/- 5% so that was our main worry and its not that.

    E38_0116.ctz Let me know what you find.

    Thanks.

    If you desperately need to get a sticker to keep driving it, there are ways to force the Readiness Tests to pass. I wont disclose how to do it, but if you spend some time on google it'll come up.

    What are your mods and what codes are being thrown?

    Mike, are you reading the readiness tests using V7 scantool or V2 LCD...?

    This is unlike any other emissions thing I have run into and none of the usual tricks seem to be working. No codes. Fails on any scanner.

    The list of mods is a mile long, boost, huge injectors, dual pumps.

    Its just such an unusual issue, has anyone ever had a similar issue?

    Hmmm... fuel system is a continuous monitor, it runs all the time, so it should come ready always.


    What DTC's are you seeing...?

    What DTC's have you disabled...?
