What year ecu are you using and out of which car? If you are using a fairly modern Mitsubishi ecu (97+) then you can use evoscan to actuate each fuel injector independently.

yea if you can grab a gatorade bottle (my favorite but any kind works) An put the fuel rail over the bottle with the fuel injector inside the bottle. Then activate that fuel injector and see if fluid comes out into the bottle!

yeah i would just take the rail out and make sure they are all spraying

to the gatorade bottle test....you could just put a cloth on the valve cover... take the fuel rail out and rest the rail on the engine...and turn it over.. see if they pulse the fuel...it would be better to get some kinda scan tool and test the injectors independently...

oh yea thats good have fuel spraying into a cloth and all over the engine bay creating massive amounts of flamable fumes. Imagine what would happen if he did that and he had a loose connection somewhere that created a spark when turning the engine over. Poof bye bye engine bay. thats just not that safe, now if you just use the CAS to crank it, with a fire extinguisher ready thats a step in the right direction. Remember flames are for the inside of an engine not the garage.
