I was doing my grounds and such last night and now my leading coil (the one in front) is not getting positive signal through the green and yellow with orange spotted wire. the negative is fine though. i tried chasing the green wire but its tough (anyone know where it goes?).
what i did last night:
-grounded from battery to leading coil bracket bolt to body.
-grounded black wire with open black connectored end to body (i assumed this was a ground and it goes into the leading coil... i could be wrong and this could be a problem)
-grounded to rear main coil bracket from strut tower
-grounded pressure sensor in engine bay and pressure sensor near ECU.... (((there is a problem here... i misunderstood some instructions from this forum and assumed that the four wires harnessing to that pressure sensor (:which doesnt have a vacuum hose connected anyways were all grounds. one of them is the ECU ground though im quite sure.. but there was also a green and yellow stripe one (different wire but same color from leading coil) on the harness.. i dont know if that pertains but its for informations sake.. I connected all four of those wires and grounded them. my engine would not start.. it just turned over. i disconnected them and put it back to harness how it was and it started.. at this point i dont know if the leading coil was not firing yet, i found out this morning. could this have fried the ECU? Are there any fuses i should check?? I just dont know)))
-grounded engine from strut tower to intake manifold bolt.

PS DOES ANYONE KNOW if the signal from the main coil (the one in back) is the same as the leading (the one in front)?!?!?! because i would just run this wire to both the coils and there would be no problem.. i just dont know if in a rotor the first and second plug fire at the same time... if i dont get replies with info im eventually going to get desperate and do this anyhow... plz have input

P.S. this morning i also found a relay with fucked up burnt out wires. i dont know what it is for. there are 4 wires to it, it goes to the side of the engine bay wall all the way in the front on the pass. side in that open area. the reay is white/grey. one of the wires is red. i think another is brown. and one is black w/stripe.. i patched it up though, anyone know what this is as well?

the black wire gives power, the green wire goes to the ecu-which provides ground.
what is the car doing--just no fire?

Yes it is Black wire with brown band = power

Main power relay for engine and ECU it may have burnt out because you grounded the power wire of the leading coil. Your ECU should be ok. Remove the grounding from your leading coil black wire. You may have also blown a fuse.
