My 2006 X320 seemed to be short of power recently when operating with the power flow unit. Find out it was running on one cylinder-I go to check the plugs and find the plug wire was severed at the shroud. So I purchase a new coil from dealer along with the wire harness to fuel solenoid as it was frayed by mice. I replace these two pretty easily and now mower will not start.
I have spark at both plugs, but only when the ground wires are detached from coils. But the mower should still start without these connected, correct? Safety switches at seat and brake are good as I tested these. Did not test safety switch for PTO as have not found it yet. The fuel solenoid does not "click" when key is turned on. I can get the mower to fire for a few seconds when gas is squirted into carb with air filter removed. So it seems like there is no gas getting in to carb. I have choked it plenty but no smell of gas. Disconnected gas line just after the vacuum fuel pump and gas does squirt out when turning the engine over. Did not disconnect the next hose segment as it would be very difficult to reconnect without pulling off carb. But there is fuel in the bottom of the carb bowl where the solenoid is located. Twice I have drained it.
So I seem to have it narrowed down to the solenoid, I think. (I have plugged and unplugged it on both ends several times to make sure I have a good connection, even reconnected the old frayed one but does not help.) But still not sure why I have no spark when the grounds are disconnected to the coils. I suspect these are related but have run out of ideas.
Any thoughts/suggestions? Many thanks for your help!
