My discovery stopped running After it was just running a couple months back. I changed plugs and wires and fuel pressure sensor and it started then a week later I guess the transmission speed sensor went out and it quit moving. I finally got the part I jumped it and it ran for a few minutes and I shut it off to change the sensor. I bought a new battery now it won't start at all. It cranks but won't fire over I tried spraying ether in it as well
