Default 85 Won't Start

I have an 85 Vette that will not even turn over like there is NO power to the starter. My car is at my fathers house and I had a guy coming to look at it today to possibly purchase it, my dad went out to see if it was ready to be looked at (the car hasn't been driven all summer) he went out to start it and the battery was DEAD, he then jumped it with a booster charger....long story short, he bought a new battery and now there is NOTHING....it won't even crank. I had an extra ECM so I changed that thinking maybe he fried it trying to jump it...nothing different. All the other components such as the dash and the headlights etc all work fine, when you try and start it with the headlights on the headlights do NOT dim at all. Any ideas?? I really need to get this car running and SOLD. Thanks!! SEAN

might be simple, but check the fuses.. I had my brake fuse go out and as a safetly feature(i think) the speedo/odom disapeared and the flip stereo froze in place. pulled over and it wouldnt crank at all. this is where are situations are relevant. but i dont think anything worked inside, like the lights/stereo/ac, so its probably not the fuses, I'm not sure, just a noob

Not sure...could be the original. But I am thinking that the starter is not getting any power since when you have the headlights on and try to start it they do not dim. I could be wrong.

Make certain you are in either park, automatic, or clutch engaged, stick. Do you hear a clicking sound? If not connect a jumper between the positive side of the battery and the s terminal on the solenoid. If the starter turns over replace the solenoid.. Don't give up..

Try cycling the alarm system on and off. The alarm has a starter interrupt relay (disconnects the solenoid power lead)- it Could be bad, or it could be that the alarm needs to be reset since the dead battery incident...

I had the same problem with my 86
Don’t forget about the VATS system (vehicle anti theft system).
That is always a problem!!!
I would install a vats bypass switch too!!!
Also if your key (witch has a resistor in it) is bad, that will do it.
Good luck
