I have a 2000 Gt with 100K on it now. Runs (use to) great till now. I parked it at home and went out to put it in the garage the next day and it started fine. The temp was -23 with wind chill. Then 2 weeks later went to start it and nothing, zero, no fuel. I put a bottle of heat in the gas tank thinking it had a frozen fuel line, and a gallon of fuel. I checked the #14 fuse under the hood and its fine. I checked the relay (inertia switch) in the trunk and also good. I know it has a relay in the right side inner frender well (dumb place). I used a multi meter to check for power at the relay cut off in the trunk and it has power. I believe that is between the fuel pump and the relay in the frender well and if I have power there then the pump is bad. I pulled the fuel line before it goes into the rail and nothing, thats after I hooked up my faithful MACTO fuel pressure gauge which I never use. So Im left to believe it the pump. Does anyone have any tips or clues? This is my first 4.6, I've owned many many 5 liters so this is new to me. I do run the tank low and relize it heats up the fuel pump. Next where to get one??? I will be modding to motor in summer with a supercharger and cams..etc. A supercharger normally come with one so I'm looking for cheap for now. Any help would be really cool.
