    well i replaced the fuel pump and it is operating fine engine turns over but doesnt fire vehicle lost power and stalled then wouldnt start again. (wife was on her way to work)i have done some basic troubleshooting dont know much about this vehicle pulled spark plug wires from top of rocker cover and one was filled with oil other three were dry again i have not had any experiance with this vehicle seems the plugs are under the rocker cover with a rigid cap extending down to them not sure where to go from this point?

    ok pulled the sparkplug wires and the number one (closest to the oil fill cap is flooded with oil the other three are dry and seem normal)plug is literally flooded to top with oil, not sure if this was a spill or sign of something else gone seriuosly wrong just my opinion everything seems to be fine with the wire and cap so it would appear that oil is leaking in from inside the rocker cover

    The oring in the valve cover is leaking on the spart plug. But that is not the firing issue. Check for fire in the cap the the plugs. Could be that simple. If not check your coil packs.

    I agree with lowcountry_shawn. Why did you replace the fuel pump? How do you know the fuel pump is "operating fine". What is the fuel pressure reading with a gage?

    for one it wasnt working so i replaced it and second circumstances indicated it was the fuel pump which was bad so as i said i replaced it but that was not the only problem obviously and now i have bad orings and need to trouble shoot the coil and distributor to find the loss of current to spark plugs, please dont ask me stupid questions or assume i dont know basic mechanics answering a query with more questions isnt helping

    You know basic mechanics, ok. WHAT IS THE FUEL PRESSURE READING. I'm just trying to help you. Don't insult me. There is people that are above your expertise.
    One cylinder with oil in the spark plug well will not cause a no start.
