so i put a d16y7 block with a d16y8 head on it in my 93 civic. i then got a dizzy of a z6 it pluged in and the car cranked if you held the dizzy on there by hand but the dizzy wouldnt bolt up to the head so car was running fine then i bought a y8 dizzy and it bolted up i cut and rewired the plugs for obd1. but now my car wont crank with either dizzy. and the IVAC is making a humming noice. all the car does is turn over and make a sound like the motor is under water or something. i have no clue why it would have cranked yesterday and ran fine but now it wont.... i need serious help please im begging you lol.
