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