Is it very cold ? or does this happen if the engine is also hot and running ?? Does it start straight after turning off ?? when engine hot ?? Regards

Regards hi buddy it does it all the times even if i had it running for few hours or even if i been driving it all day whether hot or cold it refuses to start without easy start i been reading other threads were people had a similar fault as mine i have so far taken each plug off one injector at a time to see if it start alot of people mention that i should still start if its a faulty injector and run on three cylinders i dont this test no start same as before im in uk in england weather is around 8-10 degrees so not that cold woodymk1 Jan 27 2014, 01:12 PM sounds like a bad sensor somewhere could be crank sensor or cam sensor but now you've had it on easy start it'll probably never start without it now its bad stuff engine get hooked on it also it'll knacker top end try changing the sensors and checking all wiring to injectors and glow plugs if that all fails go get it plugged in to find what fault codes are present thanks il try and see if i can find a way to test the sensors iv read alot about the engine getting used to the stuff il try and only use very little Edited by DJ_B4L, Jan 27 2014, 11:12 PM.

The Easy Start gets the engine turning fast enough for the high pressure pump to get enough pressure built up and then the injectors work. I'd get the injectors 'leak back' checked.

The engine can run off the cam sensor alone, but only if the engine is already running. The starter motor doesn't spin the engine over fast enough for the cam sensor to get a useable reading. But the starter motor spins the engine fast enough for the crank sensor to pick up. The easy start picks the engines RPMs up enough for the cam sensor to get a signal, then it runs fine. It only takes a tiny squirt of easy start to make the engine spin faster, then the engine fires into life easily. But if you need to use a lot of aerosol, and the engine slowly chugs into life, then I'd suspect the problem is elsewhere.

Replaced pressure control valve on the back of the fuel pump and vehicle started no problems,but would still cut out once revved.We then replaced rail pressure sensor and vehicle was running perfect.Took out for a test drive and 10 minutes later it cut out again,and would not start without easy start!! any suggestions? would it be wise to replace crank sensor?

Iveco technician made a mention of the crank itself having slack so crank angle sensor cant tell its position. diagnostics throw "crank speed" error. apparently would explain a leak in the engine block + rear main seal.

We've had 2.8 engines that only have a thrust bearing in one end of the crankshaft, the crank then eats through the bearing journals, allowing excess endfloat. The flywheel could be pulled back and forth about 8mm, enough to pull the flywheel away from the sensor. Iveco eventually agreed to supply the new crank, bearings and bottom end kit FOC, as this was a design fault.
