I have a 2002 escort. Started to run rough and stopped running within 2-3
minutes. Was able to start and run for a few minutes with no power,
Currently it does not start, Cranks good and appears to be getting gas.
Upon testing spark plugs with a tester between plug and wires, I am only
firing on the #4 cylinder. Spark plugs and coil have been replaced. Any
ideas on what may cause it to fire on only 1 cylinder?
