Just went through this with our 2000 Mystique on the way from SLC to Vegas. Both the Gas Pump and the Pump relay module failed together. We had no fuel and no spark... aparently the pump relay also controls the ignition firing, or cuts it out if fuel delivery fails. First replaced the relay module and then the car would start and run again but would stall easily. Then had the pump replaced at a Ford dealer and it runs like a champ again. This is a fun car to drive... we intend on keeping it a while longer.
