Do you have a voltage at the coolant temperature sensor plug ? Looks like you have lost a feed somewhere. Sent from my SM-G903F using Tapatalk

Try disconnecting the sensors one at a time and clearing the errors. Sent from my SM-G903F using Tapatalk

Don't really understand what you mean .... disconnect the sensor clear the fault and plug it back in?

[Johnboyhgt]

Disconnect clear errors, the one that allows all the others to be cleared is potentially faulty. Ie disconnect water temperature clear errors and they all stay clear apart from the water temperature. This would indicate a fault in the sensor. Sent from my SM-G903F using Tapatalk

Yes tested today , It has two life , is it suppose to have !

[Johnboyhgt]

Unplug it and test the live - what voltage is it ? Sent from my SM-G903F using Tapatalk

I've deleted all fault codes , but once engine running they are all comeback .

No eml  light on the dash .

List of fault codes:

 

P0115 coolant temperature sensor

P1105 Atmoshperic pressure sensor malfunction

P1106 Turbocharger wastegate solenoid A malfunction

P0135 O2 sensor heater circuit  ( bank 1 , sensor 1 )  CHECKED  PLUG  CONNECTION , SENSOR LIKE NEW .

P0340 camshaft position sensor . SWAPPED IT  TODAY

P0100 mass or volume air flow circuit . IT COULD RUN WITHOUT SENSOR ON BASE MAP , SO WONT BE THAT WHAT CAUSE MAYHEM .

Back to basics. Is your new ecu giving the same symptoms as the old. Ie fuel pump not priming, throttle body not buzzing. Or has an improvement been made ? Sent from my SM-G903F using Tapatalk

I home now do it tomorrow , what voltage should be ?

[Egor]

Fuel pump priming  , throttle buzzing , it starts and runs quite steady on idle  , but then fade away and starts misfire and eventually stalls

12v Sounds very much like you have lost or have reduced voltage to your sensors. 2 checks please. 1 check the voltage to your water temperature sensor at both sides of the plug. 2 check voltage at your lambda sensor on both the white wires. Report back your findings, meanwhile I will take a look at the wiring diagrams. Have you checked both blue and black connectors next to the expansion tank bracket for signs of corrosion ?

sounds like a earthing fault to me, but a starter motor can cause all types of electrical issues 

[Johnboyhgt]

Could be earth too Chill, there's definitely some link between it all. Sent from my SM-G903F using Tapatalk

[Johnboyhgt]

The one that leads me to think live though is the lambda heater which is earthed through the ecu, and as it runs you would assume that would be OK. Though as we both know the lambda's go down just for fun. Sent from my SM-G903F using Tapatalk

If you have a second to  come down at some point I will pay for  your expenses and labour  , whatever you find something or not !

[Egor]

Meanwhile I will check the voltage and the other bits...

Do the tests with ignition on, engine running ideally. Sent from my SM-G903F using Tapatalk
