There is a HEP connector under the battery tray. It can sometimes wiggle free. I would check that first.

whats HEP?

i bought a lebarron not long ago with 150,000 on it that had never had anything but mobil one in it. i recently changed the valve cover gaskets and i have never seen a motor that clean with that many miles on it. it was enough to make me switch from Valvoline Durablend to mobile one in my other cars as well. good stuff all around.
