mpfi help

ok i did the mpfi conversion, and now my fuel injectors are not firing fuel into the intake. all wiring is correct, im absolutly positivly sure of this, it has been checked 6 times. the dizzy is fireing, and it will run on starting fluid for about 45 seconds. any ideas or tips to help me out, someone please help me here. btw im going to try to swap computers w/ a friend tommarow, and maybe injectors also, because thats the only things i think that it could be. thanks

you are using an SI ecu aren't you??

Check resister box is grounded and wired prop

yes im using a si ecu (pm6), the manifold came off a 89 ex, i think the fuel injectors are bad not sure. i put my ecu in my friends crx, whcih has a zc engine, and it worked, so i know its not the ecu.
