Need Help ASAP!

I've completed my engine swap (1.5L to 1.6L). I put a new timing belt on the 1.6L. Motor is installed, and now I am not getting fire to my spark plugs. I've pulled a spark plug to see if I was getting fire and the only time I get fire is at the point when I stop turning the motor over. It sparks once.

Any ideas? Any help is appreciated.

sounds like some wiring is wrong. or coils maybe be bad. WHne you swapped did you change the ecu?

sometimes the older coil injection systems use a ballast resistor to boost the spark when turning engine over on starter, perhaps you have one of those and its playing up?

You don't have to swap the ECU from 1.5 to 1.6.. The engines run in the same perameters with the same wiring harness and sensors.

Every sensor? That seems odd though. Like I got a 89 prelude with the b20a5 and well a b20a1 same year car same everything but f you swap you neeed a different ecu even though all sensors are the same. Every paremeter cant be the same with a bigger motor. My assumtion.

Trust me.. it's been done.. Um SF-Engineering ring a bell.... Yeah we've done alot of things.. A 1.5 - 1.6 swap was the easiest..
