I have a 98 gtp and this morning the car wouldnt start. I checked for fuel pressure at the rail and there was nothing. So I bought a delco fuel pump and installed. Still nothing. I tried hooking a scanner up and it would not connect. The fuel gauge is also pegged at full but there is only a 1/4 tank of gas in it. When I key the car up, the mpg on the DIC say what it should be and then a few seconds later it flashes "0.0". Has anyone else encountered this before? Thanks
