Here is the deal. Its my grand national with the standard 3.8 Turbo and I need some advice from people. I blew my headgaskets, and I rebuilt the motor got it bolted into the car and I was doing the wiring. Then I went to connect the negative battery cable to the battery and the engine cranks. It cranks with no one turning the key or anything. My dad (smittydawg) and I am at a loss. Any help would be huge. Thanks.

Check the connections on the starter. One of the larger wires is probably touching up against the smaller post.

Check your positive battery cable at the starter. You might have it touching one of the smaller posts on the solenoid. If so it will just crank as soon as you hook it up. I put the caspers longer positive battery cable on over the winter and when I went to hook up the battery the same thing happened to me :cheers: :6:

I checked that and nothng is touching the smaller posts. This is why this is the strangest thing. I left the whole harness in the car when I pulled the motor, and just hooked everything up. Any other possiblities?

only two things, beyond what was already stated, can make it crank. Wired wrong, or bad solenoid.

My bet would still be the solenoid. When you tighten the wires up the terminal may turn on the inside of the solenoid causing a short. You may be able to turn the terminals a little and "cure" your problem until you get a chance to replace the solenoid.

Is there a way I can test and see if the solonoid is bad?

Yeah, take the starter out of the car and hook it up on the bench. Ground the case and then apply 12v to one of the big posts. If it spins then there is a problem with the solenoid. The only time it should spin is if there is 12v on the big terminal AND 12v on the small post at the same time.

Sometimes all the wires can be confusing and perhaps get connected incorrectly. Check & then recheck proper wiring first,,,
