So, the fuel pump is running. I can hear it when I turn the key.
Air ... no obstructions, other than the throttle body plates.
Spark ... none.
Timing (crank) ... sensor checked as responsive. Timing belt correctly in place.
Timing (cam) ... sensor checked as responsive.
Exhaust ... open headers, but there.
Compression ... it was there when I pulled the engine from the SVX, no reason for it to have disappeared since.
