RobertISaar Posted June 1, 2013 Report Share Posted June 1, 2013 driver's side strut tower, in a little plastic enclosure with the fuel pump relay. Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted June 1, 2013 Report Share Posted June 1, 2013 oh, and there's also a second one.... the one i mentioned is the "voltage always present" one that retains the NVRAM in the ECM. the other is in the in-cabin fuse panel, that one is used as a signal for the ECM when the ignition switch is in run or crank.

mediabandit Posted June 1, 2013 Author Report Share Posted June 1, 2013 Thanks. I went and checked the one under the hood you mentioned and figured I may as well check ALL the fuses. Not lucky enough to find a blown one. Quote Link to comment Share on other sites More sharing options...
