The oil pump is bolted to the bottom of the engine block INSIDE the oil pan on a 1995 Ford Windstar V6 engine

If it "clicks" when you turn the key,it sounds like either a weak battery of bad starter selenoid.
The 2002 Ford Windstar ECU can be found on the firewall in the engine compartment. The ECU will be on the drivers side of the firewall.
