Car wont start was new battery,starter,its getting spark and fuel. its turns overbut isn't fireing.

Make sure that the belt isn't extremely tight and they the belt tensioner isn't liked up by pulling in the belt. It should move and spring right back. Make sure engine isn't locked up. And please explain what happen with the vehicle. The fact that you replace plugs and wires and fuel filter for a car that's not turning is throwing me off. So right now we are going all over the place. But definite look at belt and tensioner I've seen a few times that a bad tensioner will make the belt wrap around tighter inhibiting the engine from turning.

DO A SMALL TUNE UP REPLACE SPARK PLUGS AND WIRES, REPLACE DISTRIBUTOR CAP AND ROTOR, REPLACE FUEL FILTER AND AIR FILTER. IF YOU ARE GETTING FUEL AND SPARK. EITHER IGNITION OFF OR VALVE TIMING OFF YOU VECHICLE HAS A TIMING BELT AND TENSIONER IF TIMING BELT SLIP TIMING IT WILL THROW OFF VALVE TIMING MAKING IMPOSSIBLE TO START CAR.

you need to check for spark at the plug if that is good then check for fuel spraying out the injectors.if no fuel then the pressure will have to be checked with a gage as the fuel pump may not be good.(common problem)if no spark then check to see if the tune-up components are in good working order.it may need a tune-up.

remove starter and have it tested at your local part store

There are some possibilities which you will have to check in this case:--
1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.
2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.
3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.
4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.
5) If all the above possibilities mentioned above checked out OK/perfect then it’s a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

If it will turn over check to see if its fuel or fire. To check for fuel, spray quick start for a few seconds into intake. If it starts and stops. its fuel. Change fuel filter and check fuel pump. If it does not start its fire, Could be distributor cap, rotor, coil, spark plug wires or spark plugs. If it does not turn over it could be battery or starter. Check battrey connections, ground strap from motor to body and ground wire from battery to motor and body.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

the starter and alternator have nothing to do with fire. if the engine turns over but wont run, the stater, battery are ok. there are several things to check, spark to spark plugs? fuel pressure? fuel injector pulse? a shop will need to verify and recommend repairs

did you check to see if fuel pump is pumping. fuel filter isnt clogged is it? but you're sure there is no spark. because if there is spark it could be air flow problems.
and you changed the ignition switch so that's not it, how about the starter. is there any noise coming from the starter when you turn key? if it isn't lined up right.
there has to be spark if you did what you said take off a wire at night and try it . electricity to start goes, ign switch battery starter(is there a relay on s10s cant remember), the alternator is here also.to coil/distributor to wires to plugs to gasoline

also it could be the wires coming from the battery , check them for corrosion. if they are really corroded could be problem. and make sure your ground is good contact. ive seen corrosion inside wires causing no spark.
just a few ideas to check.

if your car turn over and it sound like it want to start then i think it is your ignition coil so got car scrap yard get another that is your vehicle and put it in.
