Check for fuel
Check for spark
2002 chev S-10 will turn over but not start.
Is the fuel pressure ? is there spark at the plugs?
What is it doing? ddus it turn over but just wont start?
Do you have fuel pressure at the rail? Has the timing been changed significantly?
You did not teach it the trick very good.
you should first check the battery with a load tester. fill battery charge battery test again replace if needed
Try the fuel filter.
A bad cam or crank sensor can cause a no start, but the engine will still crank or turn over.
starter is out, motor is locked up or your starter solenoid is out.
no both systems have a separate flasher
it could either be a bad beattery or a bad starter
Does it turn over? Does it turn over?
