Engines need 3 things to start. Compression, fuel, and spark. Time to start process of elimination. If you have all 3 your timing may be off or something may be wrong with a sensor or the ECU.

check the Mass Air Flow sensor, if its not working right the car will start then die right away because its wating for a signal from the sensor. I had mine off once and it was doing it, i didnt understand why it would die but thats the whole reason for the sensor.

Good Luck

Did it run with the old engine? It does sound like the airflow meter. The cold start injector is getting it started but then no signal to the rest of the injectors to keep it going. Try to make sure there are no big air leaks anywhere.

So I bought this old Honda bike, an NSR250. Bit of a street racer, I guess. I'm told they're fast.

Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire.

I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed.
