Make sure you tightened the ground harness. Also make sure the coils are plugged in securely. Check for vacuum leaks.


Thank u I will try...


Found the problem, it was the relay fuse located underneath steering wheel.... After running all electric test I had no short circuit but did found that fuse #29 20amps yellow blew up... I attempt to replace new one N it blew again right away so it came to my mind that relay is causing buzz fuse blow, but after I removed all the relay fuse n put them back in(no new relay fuse bought) I replace fuse #29 N before I remove relay fuse I remove battery first so pls remove car battery or disconnect so anyways I put battery back N boom fires right up......


Correction: no need to pull relay fuse just disconnect battery for 5 mins, replace yellow 20amp fuse connect battery then boom its good to go....
