On a 1996 gGMC siera sle truck 4 wheel drive
SOURCE: Diesel fuel leak from front left area.
either one of the two rubber hoses split or a hole(or rusted out) has occured on one of your steel lines
or it is leaking from the water in fuel sensor / check valve. I will say forsure that more than likely u have a cracked rubber fuel line.
SOURCE: 4 wheel drive will not engage
Test it by setting the rear end up just barely off the ground with some jack stands and setting the hubs to lock (if they are manual). Put it in 4 wheel and try to drive away. If the vehicle does not move then very carefully have a helper check and see if the front drive axles are spinning while it is in 4 wheel and in gear while running.
Spinning axles... hubs are at issue
No spinning axles... Transfer case issue.

2 different electrical circut's that are unrelated. Ac on a 12 year old truck is bound to need some service. Take it to a trusted shop that is not hurting for work & ask them if anything is disconnected, ie: compressor power wire, high pressure switch...ect. Tell tale sign system is low on freon is the compressor keeps cycling on & off with a clicking sound or compressor does not come on at all.
Testimonial: "Thanks that relieves my mind that they might have disconnected something accidently. "

Your transfer case encoder motor [the thing that shifts the transfer case] is located on the LH side of the transfer case. I believe the control module should be located behind the dash near the light switch area.
If it stays in 4-Lo and the push button indicator just flashes for a while when you select, say, 2 Hi then stops blinking and goes back to the 4-Lo position then I would have someone hook up and check to see what service codes are present. I see a lot of encoder position sensors go bad but you really need a scan tool hooked up to the system to be able to watch what is happening as the shift is attempted. There aren't any vacuum controls on this system.
Hope this helps you out a bit!
