Does it have fuel? Does it turn over?

Does it have fuel?
check fuel pump
The problem isn't your batter or alternator or starter then. Start looking into your fuel management system. Possibly your fuel pump, injectors, etc.
power, ie battery, then starter, then spark, then fuel
Corroded battery cables, loose battery wires at the starter, water in fuel tank, clogged fuel filter
new battery,altnator,starter,changed all fluids and still not start. but it will turn over.acts like its not getting spark or maybe fuel but i hear the fuel pump kick on but still nothing. and also just replaced the ecm computer module too and still nothing need help asap thanks.
I means you have a battery problem or a starter problem or dirty/loose battery cable connections. If the battery is operating the starter and the starter is turning the engine over but the engine won't start and run, you may have a spark problem or a fuel problem.
possiblly the starter or fuel pump is out.
Most often it is the starter and not the ignition.
Check the starter, spark plugs, distributer cap, battery.
Starter won't crank over engine? Battery or battery connection issues. Starter cranks over engine but engine won't start? Being a GM product I would suspect fuel delivery problems (bad fuel pump).
Dead battery, out of fuel, defective fuel pump, defective starter, and many other things.
Have your Cylinoid examined, or checked. That runs from your battery, and is pretty much the switch between battery and starter. If that goes out, nothing will happen, sometimes you wont even hear a click. If fails to start still, check your fuel pump, or fuel presure regulator (if it's FI)
