I have a 1995 audi 90.I was driving home one day and it died going up the driveway.I checked the spark and it was good.I turned on the ignition key and I could not hear the pump cut on,so I changed the fuel pump,fuel filter and I still could not hear the pump cut on,so I replaced the fuel pump relay and I can hear the pump turn on,the car starts but will not turn over.I really could use some help,please.
