My jeep turns over but absolutely refuses to start. All accesories work but I'm getting no spark to my ignition coil and was told it could be the cps. wondering if that is true; and i'm having a hard time locating it where my haynes manual says it should be (on the trans. bellhousing). any help would be greatly appreciated! (already changed dist. cap, rotor, pick up coil, and ignition coil; plugs :& wires, fuses, relays, and battery are all good)
