If it have a wire coming from the selinoid later chances are that the ignition electrical system is bad. It's particularly possible that you may just enjoy a bad nuetral saftey switch, this is the switsh that doesn't allow you to start you sports car unless your in nuetral or Park.
What happen is that one day someone get in the vehicle and it wouldn't start, so they checked the battery and the selinoid and everything worked except when you turned the push button. well the merely thing gone is either the nuetral saftey switch of the ignition switch itself.
So fist stale what you need to do it to tryout the ignition switch, buy using a test flimsy and when you turn the key to the start position you should enjoy power to the wire that go to the selinoid if not later it's could be either nonetheless, you need to use a pullover wire to get the neutral saftey switch and after try the ignition again, if you have power at the selinoid after it's the neutral saftey switch except then it's the ignition switch.

Try cleaning the terminal, Getting new connectors and wires, (fairly inexpensive) If it starts up when you touch the rope then you know its not the mobile that is doomed to failure. so clean everything, Scrape the inside frame of the connectors with a pocket run through or something and make sure that the corrosion isnt interfering near the battery and cable.

Wait, isnt that little wire supposed to be connect to the mobile already? Do you mean when you touch that rope to the positive, you can crank it, or it automatically starts without you turning the knob? (of course that wouldnt work anyway without the push button in the "on" position) but I am sure you should own that small wire connect to the terminal also, I know my mercury does. Try departing that little wire connected and see what it does

Answers:    First of all, never disconnect the positive cable minus first disconnecting the negative cable. Always disconnect the cynical cable when you need to lift off a cable. This is for both undamagingly reasons and to insure you own the proper polarity. You might have a unpromising starter solenoid. There is one on the fender wall. It is round with two big post sticking out the top where on earth the battery cable from the freestyle connects. The other big cable goes to the starter. There are also any one or two smaller posts , too. One is labeled "I" and the other one is labeled "S". The S terminal goes to the starter switch and is what make the starter solenoid engage the starter. Is the switch flex is one the wrong terminal, then the solenoid won't work. If everything is connect properly, the turn on the push button and jump the two big wires next to a couple of screw drivers. If the car starts, after the solenoid is probably bad. Before you replace it use a try-out light to check and see if the switch flex is getting power when the key is within the start (cranking) position. If it isn't getting power when you are trying to start the car, later the electrical part of the ignition switch is discouraging and has to be replaced.
