Default No spark, no fuel after starting coil on plug conversion

1997 with built 1.8 and MS by Scott. We painted the engine bay of this car so we took all the wires out into the cabin. When we reinstalled the engine, the fuel pump wouldn't turn on by it's own, but would with at the diagnostic box. It would start and ran fine with the jumper in there and we were able to drive it to start tuning.

Yesterday we decided to start making our COP setup and splicing the wires. in the middle of it he needed to check something on his external FPR and turned the key on. I think some of the wires touched that we had spliced from the old coil connection and thats where we are. We have no spark and now the fuel pump doesn't even turn on at the diagnostic port. I can here the injectors opening when i spin the CAS though.

Have Done:
Changed back to the coilpack and tested for spark (no luck)
Changed blown 15A engine fuse under dash
Changed main fuse, head fuse and injector relay under hood
Changed fuel pump relay with know good one
Tried known good CAS

I am at my wits end here and am really going crazy. Any help would be much appreciated.

trying things on the spare miata always helps rule out problems.

Man, I almost called to see if I could help today, even if you were just going to slap a playaround tune on mine to get used to MS.

I didn't know you were rolling this advanced already.

My first guess is you had enough wires plugged into the ignitor that you could have goofed something up when turning the key. A good way to check is to see if you get any reading on the tach when cranking.

I've always run a jumper for my fuel pump, so I don't know how that symptom ties in.

I don't think it was getting a reading on the tach from what i can remember. I also tried the original ecu and it is still the same.
