El camino wont start
Make sure battery is fully charged, spray some quick start in the carburator and see if it'll run for a bit if it does, check fuel pressure, might have a clogged up fuel filter. If it doesn't check spark at the spark plugs. If you have both fuel and spark, check compression. Good luck

Cranking issue. Check battery voltage should be minimum 12.4 and check battery cables for corrosion and make sure they're tight. If everything checks out ok, replace starter
Check to see if you are able to rotate engine by hand before replacing starter to make sure engine is not locked up
