Crud from the low tank plugged the fuel filter or tank pickup screen? Check for actual pump flow at the engine. I wouldn't expect much pouring fuel down the air intake if the injectors have no flow.
If you confirm a spray at the injectors and spark, then you might be missing compression, eg if the chain is loose and jumped a tooth.
