My car will not start,i replaced the battery, solenoid,i have no power at the ignition switch and key,or dash,my head lights work. dome lights and taillights,if you short the solenoid with a screwdriver between the positive side and the negative, the starter will engage but will not run after you release the connection.is there a main fuse that controls the ignition and dash lights?the car started with a new solenoid but after a couple of miles i lost all power to the ignition and dash again.i am stumped as to what to do,and am stuck in las vegas
