ok fuck the book lets dive in.check fuse 4 under dash.then i need to see if you have 12 volts at the red wire to the injector resistor key on.if you do its the injectors or the ecm or broken wires.if you DONT it would be the main relay or a cut power wire i have never seen a main relay stop injector pulse just fuel pump power supply.below is the pgm-fi from my book.let me know if we have 12v ther is still a lot of diag we have to do so dont change out any more parts sorry we will get this fixed.
