Hello all,

I have a 1992 Civic Si hatch that I am swapping motors in and cannot get the engine to fire.

Background:
Bought the car used with a running SOHC zc and a VTEC head. Car ran great for years until the timing belt snapped. I have since bought another zc engine with a non-VTEC head. Stamp on the head is "PM3-17". The wiring harness was a mess so I ordered and installed the Rywire Budget tuck harness.
When I turn the key I have power and can hear the fuel pump prime. When the engine is cranked over, it turns over but will not fire.

I have check for spark and fuel and both are there. Cam timing looks like it lines up well with the marks on the timing cover and I have verified plug wires several times. When I tested for spark I did notice that the spark was orange in color. I have tried advancing and retarding the timing by twisting the distributor and have not had any changes.

Running the same ecu (PO8 I believe) as the mini me set up. As far as I can tell everything is OBD 1

Any pointers? Might have missed something somewhere but I'm running out of ideas. I have included a few pictures to show timing, computer, and engine I bought and am using. I'm stumped.

Help would be be greatly appreciated

Check firing order compression test and all your grounds see if something is unplugged or if you have harness plugs in right sensor it does happen.
