will not start but the fuelpump is running all the time

Asked by for the 1993 Ford Aerostar
You state that the fuel pump is "running all the time". Does this mean that it runs while the key is in the off position? I have experienced fuel pumps running electrically, but not provide enough fuel pressure. A fuel pressure gauge test is needed to know. Also, test for ignition spark.
