    UPDATE

    UPDATE: Green Hulk community I need your assistance

    My 2004 MSX 150 starts, runs very rough for a second or two, then shuts down. It was suggested to try a couple of things prior to coming back to the community.

    - Test Cylinder Compression
    - Cylinder 1 - 130 PSI; Cylinder 2 - 130%
    - There was also no change in Compression with/or without the Throttle Wide Open.
    - Also inspected spark plugs, see attached pictures attached

    - Disconnect the PPU and module to see if the machine would run batter, although only idle
    - no change, the machine still starts (rough) then shuts down after a second or two.

    Any suggestions as where to go from here?
    Thank you

    I have been told and some research I have done suggest the NGK
    - BKR9EIX "Iridium", something about these running colder.

    Try swapping the SIFB from the running machine.

    Starts rough... then dies within a sec or two.
    Agree with above... ensure it's not the SIFB module. Swap if you have known good one... or use paperclip to bypass.

    If not that... could be fuel pressure related. Maybe your fuel pump isn't able to keep pressure up beyond the initial prime? For fuel pressure... would have to create an inline adapter to get a gauge on the fuel lines using extra quick connects that are present on the fuel lines. The one I crafted looks like this:
