Have you tested the FP relay under the dash or the pump in teh tank? Could be a bad part, bad wire, bad relay -- really lots of stuff.
Do you have the FSM? IT tends to hold the keys to the kingdon when troubleshooting - best $75 I ever spent considering what a tow costs now a days.....

No power in car, no gauges, and ignition or horn excepts headlights. Engine cranks when I jump it but power inside.

seems like another perfect case of starting with the basics before even bothering to jumper and cobble it to run..
battery has a good charge and good connections (hot to starter and ground)?
you checked all the fuses?
first place we need to see the voltage is at the ignition switch, do you have power to there?
then how about power going from there with key on?
this will be enough to keep ya busy a bit because im not going to type a whole flowchart here lol
good luck

So as we are not very good mind readers on here and ESP doesn't work well over the interweb , how about some history on the car ?
Was it starting and running normally ( ever??? ) before this problem?
Have you made any recent changes ; installed / removed something ?
What has been done to it , is it new to you ,etc etc , ........
At present ,as ladystoy69 states you don't have a "Corvette" specific problem ; you have a generic no start problem .
Google "no start engine" and do the basic spark/ fuel tests 1st

It is my understanding the 84 has a security similar to this:

1. 84 had no vats
2. vats would only stop starter and fuel not dash and all interior power
again check the things i posted in my last reply

Theft deterrent system is operated by switches in the door turned by your missing keys
http://forums.corvetteforum.com/c4-t...help-find.html
Quick fix would be to bypass the Starter Interrupt Relay so you can crank the engine with the key
So pull the fuel pump out,

hotwire it to see if it works , check if it has 12V at the pump connector ( only for 2 seconds ) when the key 1st turned on

I had this argument with a friend who has an 85. If you click on the link I posted you can see his response. I'm pretty sure you have it unless yours is an anomaly.

VATS was first used in 1986. Prior to that the starter relay was controlled by the TDS (Theft Deterrent System). That's the one that is turned off by unlocking the door with the key.
It also honks the horn if the door is opened without using the key to unlock it. You can make this happen by arming the alarm and then opening the car from the inside. I did it once when I didn't want to dig my keys out of my pocket and I had the window down about 4" because it was a very hot day. I reached in over the window and hit the door unlock button. Honk. Honk. Honk...
I don't know about other years, but on my car the horn will honk if you lock the door but don't close it. You have about 45 seconds to close the door after arming the alarm or it will start honking.
