I need help !!!

93 FD recently make it runnning , but suddenly all 4 coil has no spark , i checked all fuel, connection and they all got the right voltage as they suppost to and new wire plus plug

i check ECU and find this polug and a single wire, can you help me identified them ? and where i connect them back to ?

 

That plug isn't important. Why is your wiring like that? What ecu and what coils are you using? What happened or what were you doing before they stopped working?

 

Got it like this way. I have stock Xu and a special power fc.

i remember I work on the fuel injector and after everything put back in than no spark


I double check again and again all plugged in ground and nothing lose

 

Are you sure you plugged the coils back in? There is 1 connector that they all join to. Is the ecu plugged in fully and the ground attached? Is the ignitor plugged in? Did you unbolt the grounds on top of the motor when you did the injector work?

 

All plug in and bolt back in I recheck them 3 times
