91 Sable Will Crank Over But Won't Start
Got a 91 Sable that will turn over but won't start. Has plenty of gas. Is getting fire all the way to the plugs. Fuel pressure holds at 40 PSI when you turn the key on & while cranking it, but drops to 10 PSI when you open relief valve on the pressure guage (don't know if this is right). Tried a new fuel pressure regulator, no change. When you turn key on you can hear the fuel pump kick on, but it doesn't shut off until you turn the key off. Took air filter tube off & spray starting fluid in it & it fires & runs til it burns it out, but that's it. Any suggestions would be great.
