[QUOTE="hotcobra03, post: 16004204, member: 53096"] ok let's regroup.. 1st..I'm on pc in full manual.just today. what you have found. pcm relay f26 blows only when relay gets energized. pin 24, of CCRM circuit 1118 is the out put 12volts.. so something in harness or component connect is cause. 1,,remove all known components along curcuit 1118.. 2 completely unhook all ends of said harness.. 3,,what's left is just a pile of wires. 4,this must be done to isolate pg151-23 shows inside kick panel. unhook the rest of the connections. c214,c215,c210,c175. than fender well..it looked like evap and maybe something else.. than it should be just wires . c214 also has circuit 1118, let's go back to pin 24..and retest. pin 24 c1262 to pin 34 c133..circuit 1118 this should be 0s.. pin 24 c1262.to pin 2 c214 should read 0s. that's it. test every pin on every open connector..
