How to test powerpack Yamaha 150 trx carbed outboard

You can not test any power pack. You have to test all other ignition components first. If all components test good it could be a bad powepack. First thing first, check ground wire, check all grounds. Make sure no carosen, or loose bolts. Your also want to ensure wire to terminal has a good connection.

I have a 2000 150 johnson outboard was runing fine yesterday it has spark and good fuel it will fire for one to two seconds then die

Disconnect blk wire with yellow strip, from the power pack. Try restating motor and see if that cleared it up. If so, you have disconnected the kill wire at power pack.Let me know what that does for you.
