1997 Mercury Cougar
 

i own a 1997 Mercury Cougar XR7 4.6 v-8 i have changed plugs, plug wires, crank position sensor, camshaft position sensor. i have checked fuel pressure, coil packs. i am still having cranking issues, it might crank with one turn of the key,it might decide to just spin. does anyone have a remedy other than a bonfire, or boat anchor?
