Looks like complete loss of oil on the mag side cylinder. Oil feed line was completely dry when oil tank was removed. Pump appeared to be air locked. Bench tested pump after bleeding air out Seems to be pumping oil evenly from top two lines but not the bottom one. I’m thinking replace pump to be safe. Also plugs had white carbon on them. The ecm has red dot. Assuming no update to it. Seems to be a lean condition. No major oil residue on the mag side crank seal. Any advice would be appreciated

If you tip the sled on it’s side with very little oil in the reservoir it can create a air pocket, thus no oil in the line(s). Plug reading you mentioned is a lean down issue, melting metal.
