Ok I did the mpfi swap triple checked all wiring and im still not getting any spark or any fuel to my injectors. please someone help me, what is wrong? the people at the honda service dept. tells me swap is impossable. btw i have a 91 dx hatch. im absolutly sure i hooked everything up right. only had one plug (black/yellow and orange wires) left over, which im told was correct. please someone give me some advice. ok here is the rundown, the black and yellow wire has + battery voltage going to it, the blue wire has no voltage going to it at all neither + or - All injector wires, (brown, red, blue, and yellow) along with the resistor wires (red/black) all show a neg output. The fuel filter is ok, and the fuel pump comes on. Where the hell is the main relay? Im guessing it is working. How do I check the crank sensor for pulse or signal? It is showing a neg output when key is on. What ignition wires do I check, and how? thanks
