1990 Chevrolet Suburban 2500 Q&A

1990 Chevrolet Suburban 2500 Question: What would cause engine failure, headlamp failure, when vehicle is put in revers

We have already diagnosed the truck with starting fluid Ignition works but immediately quits. Incidentally no headlight power to the main switch? ODB port also has no power, I suspect it is through a power circuit short or relay problem but i also suspect the shifter itself, i tried finding neutral in it and turning motor but wont engage started. There seems to be excessive play in the shifter on the tree... 2-3" in park, i havent driven or worked on a chevy of its like since 2000 since then ive stuck to 1990-1993 fords with straight six's any inpuit would be appreciated -
