86T z31 wont start

about last saturday, my brother took my 86 turbo out for a spin and calls me it just turns off around the corner. i found that strange cause i had just gone through the engine and fans earlier.
it ended up being the TPS cable that goes to my ecu i believe, touch my exhaust manifold, it only bearly touched a purple wire.

now my car doesnt start, it doesnt have spark (i disconnected the wires from distributer to check)
and my car came with a Apexi SAFC and now that wont start up.
Checked the fuses under the dash and they were all fine.

can anyone shine any light on where to go from here?
