I have a stock 2000 Mustang GT with 90,000 miles. I can’t get the car started and I know that the fuel pump does not run when the key is first turned or while the engine is cranking (can’t hear the whining noise like usual). There is no pressure at the fuel rail when I try to start the engine. The problem started up about a month ago when the cold weather came through. It would take me a couple of extra cranks to get the car started and now it refuses to start at all. But when I could get it running, it would start right up instantly as long as the engine was semi warm. Right now it’s at a shop and I’m having doubts about their diagnosis.
The shop said they need to replace the fuel pump but couldn’t guarantee that it would fix the problem. I assumed that they did a poor job of troubleshooting and told them to not replace the pump. Right now it seems like the culprits could be PATS, PCM, CCRM, FPDM, inertia switch, fuel pump, bad ground or short, or the camshaft position sensor.
Another strange thing is during the past couple of months the tach would stay at zero for a second or two after the engine fired up and then functioned like normal. The tach used to move instantly when the engine started. Could this have anything to do with my fuel delivery problem (faulty electronics)? I hope I can get this issue solved soon as this is my only means of transportation and I work 20 miles from home. Thanks for the help!
