Thank you, I will try changing out the ignition switch. I 've tried starting it in neutral, no luck.

Where is the ignition switch located?

Again thank you ,

Before you go to that expense, put a 12v jumper to the starter solenoid to be sure that the fault is NOT in the starter or solenoid.

Right..
...Here is an old post that may fit your chassis.. it if from a 124 posting

< If you look over at the brake booster, right at the brake fluid tank cap level, just to the left on a wall, you will see a plug connector screwed to that wall with 3 wires .. this is plug X/27 and the V/WT wire is the feed wire to the starter solinoid.
If you hook a 12v test lamp to that wire [ back probe it], and that lamp lights every time you turn the key, you know all the electronics for starter are in tack and operational, but the starter itself, or solinoid, are at fault..
There is a K38 relay in the dash, but if this lamp lights , we know that is OK
[ and you are lucky on that]
One last simple test before pulling the starter.
Next time it does it and you know you have power to X/27, grab some battery jumper cables and hook one end to the bat - [ neg] and the other end to the engine somewhere good [ metal] and retry.. this assures a good ground from bat to eng/starter..prob not the problem, but so easy to do, that it's a worth while try ..I like to be sure of the simple possibles first.>>
