Need Help!

Hi all,

 

recently I face a problem when I start my engine, occasionally about once out of 10,

in normal once turnning the key to 'ignite' position and hold 1 to 2 secs, release the key, engine will start, but sometimes when I turn the key to 'ignite' position and hold 2 secs, engine couldn't start, tried again and held more than 5 secs released the key, felt the engine seems was running slowly, got "koon tong, koon tong" noisy and vibrating hardly, looked like only 1 or 2 cylinders were working , immediately cutted off power supply, and tried again, things back to normal

can anyone advise me what is the possible problem? thanks alot

Check starter B+ cable to battery positive terminal for corrosion or loose contact. Check starter soloneid wire from starter switch, for poor contact. If all ok chance the solonid may need a replacement.
