I Had it towed home I replaced the fuel pump,and fuel pump relay it still will not start .when I turn the key on I can''''t here the hum in the tank, I checked the old fuel pump by hooking it up to the battery direct and it works. I used a test light to  check the ECM B fuse (inside under dash ) for power it had power on both sides I also checked the fuel pump relay wires,the orange wire had constant power the other wires have power for 2 seconds when the swith is turned on,the black and white wire does not have any  power either way I went to the back where the fuel pump wires hooks up and checked the plug( purple wire) that supply power to the fuel pump it had power but it was weak < Message edited by cheapride -- 8/21/2008 5:33:06 PM > Post #: 1
