Greetings! U could have a bad fuel pump. I would rec to check fuel pressure. Fuel injected cars are very fuel pressure sensitive. Fuel pressure is very important and must be within specifications! But if the pressure is low, it does not mean the pump is bad. A plugged fuel filter, a pinched line, and low voltage at the pump can contribute to low fuel pressure. Both must be checked before replacing the pump. U can get a fuel pressure gauge at a local auto parts store for cheap. Good luck!

Sorry for the delay. Yes! If there is spark coming out of the coil, and there is no spark down at the plugs, than it is being interupted somewhere. I would replace the distributor cap and the rotor for sure! Plugs and wires maybe can wait. But I strongly rec to do everthing.
