Starter issue

Try resetting security system if no owners manual look online for your car.

the car will start with "Easy Start",

The fuel pressure may be low, any codes? starting with spray? will it keep running or will it die again?

No codes, yes kept it running on tick over and also variation revving for 30 minutes before turning off, still would not start off the starter.

When you say it will not start with the starter, but the starter turns the engine, then check to see if you have spark and fuel to the engine while cranking the engine. There is a chance the bad starter damaged wiring to the ignition or other components. Also, make sure you have a good ground to the engine block from the battery.

Diesel...

Did the engine run okay before the starter change? if so I would say go back over the starter to see if some wires were put in the wrong place.

Yes, the engine was running fine before, wires cannot be put in the wrong place as different fittings, (only 2 )

Could you have bumped and damaged some wiring near the starter when changing it? The reason I ask is because 9 times out 10 its something we did when changing the part if it happens right after the repair.

Been over the wiring and pipe with fine tooth-comb, even replaced the crank-sensor which is just below the starter motor.

Did you disconnect the battery when changing the starter? Is there a change it had a short, please check the all fuses just is case.
