had the same problem spent 2 weeks traceing it out just about riped the car apart ended up being the fuel/ignition control(i think this is its name but heard it called couple other things) anyway its under the dash on the driver side you need to remove the lower instrument panel cover(above your knees 3 screws hold it then you need to remove the metal panel reinforcment(4 ten mm bolts)its the only brown box youll see when you look up its just left of the steering colum if you unplug it wait a sec plug back in it will start i still drive with the panels off its a pricey part hope this helps
