Outer Limits 4x4 Board

My hzj79r landcruiser utility has s few issues that are concerning me. When I start it cold it will start instantly but when warm/hot it will take about 4-5 cranks. Yesterday it started doing it when cold as well. My fuel economy isn't great, I'm only getting like 400kms tills its on a quarter tank of a 90 tank. I'm new to the cruiser so maybe it has a large quantity of fuel left from quarter to empty? From my research I'm leaning towards injection pump rebuild time. I have 211000 ks on her. Has anybody else experienced this? All help is greatly appreciated.
Cheers Tom.

I have recently purchased a 79 series factory turbo diesel, I had a few issues also as in it was running at 50% power, 68Kw at the wheels. I've since had a tune, chip and 3" exhaust fitted, it's now 131kw at the wheels and 695 NM torque according to the rolling dyno. Assuming yours is also a factory turbo the best place to start is valve clearances. At 211000 you shouldn't need to rebuild the pump. I have 200,000 on mine and it's fine. I guess youv'e changed the fuel filters ? Put a good injector clean in the tanks and also an anti- algee treatment, diagnostic on mt ute cost $260, I had big exhaust leak, and the valve clearance was adjusted. I get about 400kms out of 45 litres mixed highway and city use.
