Anyone know how to test injectors to make sure they are firing at the right time ir even at all???? also, if im using b16b injectors on my d16y7 harness (engine swap), are there any mods that have to be done to make them work? the harness plugged intothe injectorsjust fine by the way...

 

Unplug an injector and connect a small light bulb (like a #194) to the plug. The bulb should flash when you crank the engine if the ECU is driving the injectors. It would be unusual for them to fire at the wrong time, even if they did the engine would still run just not quite as well.

 

ok, but is there any actual way to actually test thie injectors themselves to make sure they work?
