John Deere lx288 and 425
My 425 isn't getting any spark on left cylinder.
I switched coils and spark plugs and still no spark on left cylinder.
Right cylinder fires with either coil or spark plugs.
Any suggestions what to check next?

Bad spark plug wire?

Clean and reseat any connectors in the ignition circuit.
This engine has two pulser coils mounted near the flywheel.
Swap them and see what happens.

I swapped pulser coils and still only fire on left side.I lightly sanded contacted,tested connections on each side of plugs and they are continous.
I measured resistance as in Manuel and both passed.
What does this suggest?

Rob,

It would be best if you would have just one thread on your issue.

I suggest that you contact the moderator and ask him/her to combine you post.
