This resistor may cause an issue with the code being thrown, but I think you have another issue with the fuel pump. One of the troubles you run into when you deviate from stock is you really, REALLY, have to know your shit with some systems. Some systems have a failsafe, some don't, some work with a code, some don't. It's tough to say... we'd run into stuff like this a lot at Nissan and the more complex the vehicle, the bigger issues minor changes would cause. Sorry, I don't think that answered the question... Go to Radio Shack and get the correct resistor. Or find different directions?
