hey guys im having problem with my 94 integra ls...recently i had just dropped a new ls motor in. the motor was obd2 but i used my original obd1 harness. swap went easy started the motor car running fine. had a check engine light pulled code and fixed that problem. the other day i go to start it up and it will crank but not start...my check engine light will not light up at all i have fuel pressure but no spark. i replaced coil and ignitor but still nothing i tried another ecu and still no mil. fuses were all good the ecu fuse was not blown. im just looking for some suggestions on where to start im thinking there is a short but im lost right now.. any suggestions would be a huge help thanks guys...

 

Did you swap over the distributor ?
