Can injectors contribute to hard starting? Coincidentally my fuel economy has been tanking over the last couple years, along with hard starting below 25F...

Having the Valves adjusted been a big help for People with hard starting as it can effect the compression.
If you do it yourself and don't buy the Special Wrenches; with the exception of the Valve Cover Gasket it is nearly free to do the Valve Adjustment.
Starter cranking speed, Engine Compression, Camshaft Timing, Fuel Injection Pump Timing, Glow Plugs, Block Heater, good Battery (with good cable and ground connections), Fuel Supply System and good Injectors all have an effect on starting.
Also as mentioned Synthetic Oil is a big help in starting in Cold Weather as it allows the Engine to spin faster than with normal Oil.
