Okay so I got done swapping the gf's hatch got it running without vtec wired up (94 dx) ran good for a day then last night I pulled it in my garage to wire up vtec. I got all finished and went to start it and nothing. got a code 15. I looked over my wiring to see if i possibly messed anything up but everything looks good. Do you think its possible for the ignitor or dizzy to just go bad like that without any warning signs?

 

Okay i replaced the coil and ignitor with known working ones and im still getting code 15... WTF is wrong.

 

Do you measure battery voltage at the Blk/Yel wire attached to the coil and igniter unit in the distributor?

Do you measure ~10V at ECU connector terminals A21 and A22 for the Yel/Grn wire attached to the igniter unit?
