Really wierd one here.
Long story short, put a cx7 engine into a blown ms3.
Pulling the valve cover found after install that the oil is a bit milky. All four cylinders show about 30psi cold for compression. For reference, my ms6 cold shows about 150.
Any idea what the FUCK is going on Figure...
Any help y'all?
Gen 1 mazdaspeed 3 cranks with spark and from what I can tell fuel but it won't start.
New battery.
Spark plugs are new/clean/gapped.
Checked the HPFP ground, and when I pulled a coil pack I confirmed the spark plug was sparking.
Car sat for a year or two, could bad gas...
