Looking at an 88 .. dash and computer dark in Park, Reverse, and Neutral

[rhubarb9999]

I looked at an 88 today.  74K miles .. almost perfect interior.  It has not moved in at least 10 years.  Here is the issue I am having.

 

Hooked up a battery.  Interior lights up.  Turn the key and the Service engine and brake lights come on .. and I hear the fuel pump.  But no dash or computer .. and it won't turn over.

 

As soon as I move the shifter into Drive, the dash and computer light up in all the lower gears.  But I can't turn over the engine in gear.

 

Before I buy it I would like to hear the engine at least crank so I know it is not locked up.

 

Any ideas?

Should also crank in neutral. Is the CRT coming on ?
