Question about 1999 Yamaha FZX 250 Zeal
Went to start it this morning ...didnt fire tryed bump start no luck tryed looking at fuel pump as it seemed quiet it seems to work as i ulled outlet off and it buzzed fuel came out getting spark from leads to head ill try spark plugs i guess battery is fully charged nice clean fuel oil is good do i need a new fuel pump how do i tell if the plugs are dead
any advice would be great
The spark plugs if they are blackish it means rich on mixture and thus they have fouled up and will give you hard start. If they are brownish whitish tht means they are ok, and if they are whitish means the engine is running lean.
Since you checked the the fuel pump and after removing the pipe fuel gushed out it proves tht the pump is functioning.
Getting back to spark plugs....remove one of the spark plugs and earth it on the cylinder head somewhere and fix the lead head to it and thn crank start the engine and see if theres good bluish sparks at the spark plug.
I would recommend you first to examine the spark plugs , replace them if necessary and try to start it.
Hope this helps!
