took my car to get tuned/started my swap was complete but wouldnt start. im not getting a signal from the trigger wire. so i figure maybe a bad coil so i relplace it nothing. so we test further and im not getting any juice out of msd box but getting power too it so i go out replace it and nothing. the only wiring i messed with is the 7 wires for vtec and knock etc the ignition is wired correctly what can cause me to get no spark besides alot

i have a b18 in 94dx with aem ems
