Ragarding the starting issues, search for a thread started by me about a year ago, "fuel accumulator failure analysis", run the simple test, and go from there.

The viscous mechanical fan clutch should tighten at about 100C and if it does, you will hear a lot of "fan roar" at about 2000. If not the clutch is defective. Also, when very hot - say over 100C when you shut down the engine the fan should have a lot more resistance to hand rotation than when cold.

The two electric fans should engage at 105C. Test by letting the car idle to that temperature or a little above.
