AT MY EITS END WITH THIS ONE!

[Brendonm9477]

I have a 63 plate astra 1.7 cdti a17DTC

This car came to me as a non runner,

was told it ran ok but kept going into limp mode due to SCV, previous keeper attempted to replace injector after leak off snapped and started leaking.
they unscrewed the top of the injector?

anyway since i have replace the injector, SCV and fuel pressure sensor on the end of the rail. still wont start

i have no throttle response. it will start momentarily then shut itself off after clock sweep.

reoccurring codes:
P1297 FUEL PRESSURE REGULATOR NOT LEARNED - FAULTY FUNCTION - PERMANENT (CANNOT CLEAR)
P2452 DPF DIFFERENTIAL PRESSURE SENSOR - FAULTY FUNCTION PERMANENT

Codes read using DELPHI Diag. WRITE OPTION IS NOT AVAILABLE.

it doesnt run on spray either, before or after maf, so i am lost.

and direction would be great!

previously was getting over pressure reguralarly until parts replaced.

RE DPF, casting back from my DPF sensor issue I'm sure the sensor has failed.

you will have to run through the steps to confirm.

for the fuel pressure it needs learning.
