1989 GMC Sierra V8 Four Wheel Drive Automatic 57k miles

89 gmc 3500 4x4 cranks but wont start however it will run when u use starter fliud then dies when the starter fluid burns up, I checked the coil, fuel filter, fuel pump relay, and fuel pump, I noticed that the parking lights arent going on when I try to turn them on, the head lights go on when I pull the switch all the way out but no parking tail or marker lights,
i also noticed when I turn the key on the ck engine light doesnt come on. I wonder if that has anything to do with the truck not starting?
thanks
Tony

Tony:
If it starts with starting fluid, it is a fuel related problem. Have you checked fuel pump pressure to see if it is producing? Here is a how to video if you need directions. Check that and let me know what you find.
