Can any one help, I changed the oil, filter and fuel filter. Ran the car up after to run the oil through the filter. Watched the GP then came back to the car and it wouldn't start. The battery died almost straight way and the fuel gauge was on zero?? There's no leaks at all but am missing 1/4 of a tank of fuel. Ive topped it up with fuel and have fuel up to the pump on the back of the engine, but nothing, the battery is on charge but it doesnt catch. Anyone with ideas? Need the car to take the kids to school in the morning.
