Hi All,
Anyone here able to point me in the right direction?

I have a E90 N43 which cranks but will not start.

Background:
It ran very on fuel a few days ago, sputtered and then died.
Filled up with petrol but will not start.
Called RAC, they could not diagnose anything.
Local garage wants to replace all the injectors (cost £1500) but are not sure if that's the cause of the non start.

Symptoms:
Car cranks but does not start.
The engine floods immediately.

Things I have checked/tried:
1. Removed spark plugs , they were wet and dirty.
Reinstalled after cleaning and drying.
2. Checked spark, there is spark in all the cylinders.
3. Checked signal to Injectors all, all injectors have signal.
4. Removed and checked injectors, petrol is sprayed from each injector.
The injectors do not leak.
5. Checked fuel pump, pump can be switched on from INPA.
6. Checked fuel pressure with gauge, there is pressure in the lines.
7. Low pressure fuel sensor was stuck at 6105, replaced sensor it now reads pressure. After replacing the sensor it reads around 5300 hPa, this seems high as it should read around 5000 (+/- 50). I'm not sure if it needs re-setting/coding.

If I clean the spark plugs and let the cylinders dry out, there is an initial kick when it tries to fires up then the engine floods.
It’s seems to be over-fueling, air/fuel mixture is too rich.

Perhaps the EKP module is faulty causing the higher pressure in the Low pressure fuel lines; resulting in too much fuel going through the injectors into engine?

I'd like to check if the throttle working properly, but I’m not sure how to do this.


Attached are the errors read from INPA.

Any assistance is appreciated.
Thanks
