1998 Lincoln Continental Fuse keep blowing

Took it in to a mechanic and they replaced the blown fuse and it drove fine but the fuse blew again and the car wont start

You need to identify what that fuse powers-If its cranking over and will not start do below to determine if its a fuel or spark problem causing it not to start.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
