Another thought. Plug in your original ecu and key reader. Tape one of the chips to the key reader. Try start it up. I suspect you will get all the same codes up. Sent from my SM-G903F using Tapatalk

Reading from lambda pin 1-12.30 volts

                                    pin 2-3.60 volts

reading from t/sensor  pin1-12.30 volts

                                    pin2- 5.03 volts

 

tomorrow going to try running the car and disconnect the one by one and clear the faults after each disconnected , like Johnboyhgt  advised .

What can I try regarding earth ( ground) , check continuity , resistance on wires itself ?

Put a jump lead from negative on battery to the block/gearbox and then link to the ecu housing

A short story about my original Ecu .

I've had a problem with the car , it would not accelerate past 4000 rpm sound like run out of petrol , but when disconnect air flow meter it would run perfect .

Someone looked at lambda wiring and said the pins on the sensor in the wrong way , so I swopped them , it would make no difference , in fact it was worse , so I left the it , car was parked up for a couple of months , when I decided to move it  was not able to start .

Next I found there loads of oil in the inlet manifold , so did the compression test , cylinder n1 down to 50 psi , so bought new engine , and when fit it car has no sighs of fuel pump priming or throttle body buzzing , also could not to enter for a diagnostic too.

Do I use terminal that in the left sill on the chassis ?

Thanks

[CHILL Gone DUTCH]

No Just run a jump lead from battery over the roof and on to gear box

[Egor]

I will try this tomorrow .

Thank you

Bad MAF sensor????

 

No MAF= runs good

With MAF= runs bad

= bad MAF

 

code P0100?

MAF was replaced , no difference .

Tibby is trying to say perhaps your replacement was faulty. Sometimes the aftermarket ones are poor quality. Sent from my SM-G903F using Tapatalk

Yes , that is right some aftermarket staff already faulty , but you know about car a bit and its not that .

Was trying to crank it today , would not even do anything  at all ...

[Egor]

 Sounds like timing out , but timing is fine..

[Johnboyhgt]

Not at all Chill, do like a challenge though especially wiring. Sent from my SM-G903F using Tapatalk

tryed bad earth , running jump lead from battery to engine / gearbox and to Ecu . Also disconnected lambda 1 ,2 sensor , maf . There no difference , for some reason engine not fire at all ! Can't hear fuel pump priming , is it suppose to make buzzing sound every time ignition on ? How this alarm works , can I by pass it ? Thank you

[Johnboyhgt]

Alarm isn't linked to the immobiliser. Sounds very much like you have the same fault as you originally had 2yrs ago. Sent from my SM-G903F using Tapatalk

Nice one John , how do I bypass it please , cross the wires or just disconnect it ?
