Here are some suggestions din bro (taken from my Haynes Workshop Manual for my vehicle):

Engine rotates but will not start:

1. Fuel tank empty;
2. Battery discharged (engine rotates albeit slowly);
3. Battery terminals loose or corroded;
4. Fuel not reaching carburator or fule injectors; check for clogged filter or lines;
5. Choke not operating properly;
6. Faulty distributor cap and rotor;
7. Low cylinder compression;
8. Valve clearances not properly adjusted;
9. Water in fuel; drain tank and fill with new fuel;
10. Defective ignition coil;
11. Dirty/clogged carburator or injectors;
12. Wet or damaged ignition components;
13. Worn, faulty or incorrectly gapped spark plugs;
14. Broken, loose, or disconnected in the starting circuit;
15. loose distributor;
16. broken, loose or disconnected wires at the ignition coil;
17. Timing belt failure;

Subukan mo muna ang distributor cap bro. Tantya ko dyan ang problema. HTH.
