I need help. We put a d16y7 into an 88 civic std and it wont start. all it does is crank. It has all of the multiport swap parts in there. Its getting plenty of fuel but no spark. It only sparks once when the key goes from off to accessory, it sparks once but it does nothing while it cranks. it has a new distributor and a cap and rotor off a car that is known to run fine. any help would be great. thanks
