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.

ok im going to take it a couple of steps farther to check the main relay.check fuses 4 23 19 see if you have 12 volts at the yel/blu and the blk/yel key on. do a continuity test on the black wire.so if it doesn't have 12v at blk/yel or yel/blu you have a bad fuse or a broken wire.if it failles the continuity test you ground is not connected.if it pases the 12v test and the continuity test but you dont get 12v and the red wire on the injector resistor its the main relay or an open from the relay to the injector resistor.

ok if you get 12v at the red wire at the injector resistor but still have no injector puls check to see if you have 12v at each red/blk wire to the injectors.if you don't you have a open from the injector resistor to the injectors. if you do check the ohms on the injectors 1.5 ot 2.5 ohms.ok if that passes you will need to do a continuity test from the injectors control side to the computer take the computer connectors off first if you get continuity is the computer if you don't you have a open in the wires from the injectors to the computer.
