Thank you Gilly and all, I will persue these avenues next. As for the fuel filter, I had a new one installed but now wonderif it was the right one. I checked the Fastlane catalouge and see there are different filters for cars with dual fuel pumps as opposed to sngle pumps. If it is the wrong filter could it cause the car notstart?
Thanks again,
