2001 Chevy Silverado 1500 not getting fire to plugs

Start by checking battery voltage, should be 12.4 minimum, spray some quick start in the throttle body and see if starts, if it does, it's a fuel issue. Check fuel pressure. If not, check spark on spark plugs. If you got fuel pressure and spark, check compression, it might've jumped time. If everything checks out good, check the catalytic converter. Are you getting any engine codes. If it starts with quick start and fuel pressure is good, replace crankshaft sensor
