1986 Chevy Blazer how much to time a engine

Do below to determine if its fuel or spark problem

Get a starting fluid/ether/better off gas in a spray bottle and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it

i have taken out the spark plugs and clend them and that didnt help i have pourd alil gas n the carb but it did help what it does is when u turn the key it turns over and the pullys turn but it wont start the onjectors do spray out fuel
