I have a chevy blazer 1999 that will not turn over: starter is good, I can jump the post's on the starter and will turn over and starts the car. When I turn the key to the start postion the lights on the dash goes out, and will go on after I release the key. Could the key switch be bad or is the neutrul switch bad
thanks

The purple wire at the starter solenoid should be hot, with key in the crank position. The neutral switch is one possibility and the starter relay is another. Check out the diagrams (Below). Please let us know what happens.

Hello, does the vehicle crank ok? On a lot of GM vehicles there is a purple wire goes from the ignition switch to the starter solenoid. I really can't be sure from here.

The vehicle is slow cranking even with a boost. The third wire has a connector partway down that is broken up and cracking and a little further down there appears to be some type of fusible link. Not sure where it goes. Can it be bypassed or eliminated?

I have attached a schematic. Look at it like a map and go to section A-3 for the starter. What I see are two wires, a purple and a black one. One goes to the switch (purple) the other to the battery (black). Take a look at it and see if it helps.
