    Fuel PSI and volume tests can be observed in RTFB
    yeah, i know..... i ended up going to a site that someone (likely you) mentioned a while back and paid $35 or something for 24hr access and basically pulled down the whole repo, but while going through the repair manual i didn't notice any testing stuff. i should get the bentley though.

    howdy yall. had to take a sabbatical due to work et. al., but i've gotten back to testing.

    - injector spray pattern is good and produces a pretty cloud.
    - all new plugs
    - replaced #1 coil and no change
    - compression test == #1 ~ 155psi ; #2 ~ 165 ; #3 ~ 160 ; #4 ~ 130 ; #5 ~ 165 ; #6 ~ 95

    Corollary:

    can i do a wet compression test on #4 & #6 to see if rings are bad?

    I also need to still test the leads and grounds

    also, i was wondering if you could direct me to the D22 (over fuse 234), in wiring harness, front. i have discovered a burnt heater wire on B1S1 which goes to that lead and i would like to replace with 18ga wire from advanced. so, i was figuring to just wire it in after the fuse.

    besides that, all the leads to the OXS's are good down to the sensors themselves.

    will do. i was wondering, may i still take you up for the offer on the components?

    also, what is your opinion on the compression values? should/could i do a wet test with a little bit of oil to see if it seals the rings to either implicate them or not for the low pressure?

    topest_rex Regardless of wash down or what ever, #6 does not technically have enough for a fire event, IMO. Could oil it some and see if it looks like rings or not.

    YES to both and fuel from misfire has probably washed the rings, so yeah coat them with oil and see if you can get them back.

    i've just did a wet test on the #6 cylinder and have gained another 20psi. so, i would assume that the ring has washed out leading to low pressure



    the D22 connector over fuse 234 is what i'm looking to tap into with a new wire.

    Soak the zylinder with KANO "kreen" then light oil like marvel mystery oil.

    Get a handle on the wiring and let me know if I can help
