92 cavalier 2.2 ecm? please help

My lil' brothers 92 cavalier started pushing fuel out the exhaust. Noticed this and ran the obd test, no dtc's. checked the injectors and the #3 injector was hanging wide open. engine had bad knock from this. replaced injectors, no change in results and no dtc's. is it the ecm that might be fried and needs replacement? and if so, anybody got a spare? :confused:

If all the other injectors work fine and its just that one hanging open its probably not the computer. Check the wires going from the injector all the way to where they group with the other wires in there. You may have something grounding it out and leaving it open. Hope this helps.

thanks man

no problem keep us posted.
