Help, I have code 15 SC Motor Position Sensor (MPS) I have spark, but car will not fire, I have looked for this sensor with no luck, 3.0 sohc I found out code 15 has to do with the anti lock brakes, now my fuel pump will not turn on, so I replaced the pump and relay and still have no power to the pump, I checked the hot and ground and there both good, here`s the thing though, if I hook a test light to the hot wire going to the pump and ground it to the frame and turn the key on no power, but if I turn the key on and try to start the motor there is power. so I hooked the test light to the hot wire and the ground wire coming from the relay to the pump and turn the key on no power, same set up and turn the key to start the motor still no power. now I`am stuck on what to do next

 

the pcm's on that model diamante went out quite frequently. would give you all different kinds of symptoms. best way to diag pcm issue is to see if you have injector pulse at the injector connectors. will have to have the correct noid light to plug into one of the 6 connectors. when you spin it over and the noid light flashes brightly, the pcm is ok for now! if no flashing, pcm is bad. good luck!

 

Thanks for the reply. I did the noid light test on one of the injectors and the light flashes brightly. do you have ant thing else I can check? Thanks John
