Fuel Injector Timing: Opel Astra G Error Code 0149

Hi everyone.

A few days ago, I removed and cleaned the intake manifold from my Astra G 2.0 DTI 16V turbo engine, type Y20 DTH, which has 130,000 km on it. To remove the intake manifold, I had to detach the diesel lines from the fuel injection pump on the engine block.

Everything is reattached, the fuel injection pump has been bled, but it still won't start.

Error code P0149: Incorrect fuel injection timing / fuel injection pump.

Before I started working on it, the Astra was running well.

Does anyone have any ideas on how to adjust the injection timing or fix the problem yourself?

Best regards, Claudy.

How did you bleed the fuel injection pump?
Does diesel fuel leak out near the injector nozzles when you loosen the retaining nuts? (Wrap a cloth around them. Be careful, as there is high pressure that can literally penetrate the skin.)

Greetings.
Sure, here's the translation:

"Guste" is a German word that means "gust" or "gust of wind." It can also be used to describe a sudden burst of something, such as laughter or anger.

Good evening, Guste.

First of all, thank you for your reply.

Connect the ESP fuel return line to an external 12V fuel pump using a clear hose, and ensure the fuel supply line to the ESP is always filled with fuel. Then, prime the system by drawing fuel until no more air bubbles appear in the return line.

2. Yes, there was a good amount of fuel coming out of the injectors when the fuel line was open (I tested this today with cylinders 1 and 2).
I'll take care of cylinders 3 and 4 tomorrow as well.

Okay, I'll also seal the fuel filler neck with a cloth and then carefully apply compressed air to the fuel line to see if any diesel leaks out at the filter. (I read about this in another forum.)

Let's see how it goes tomorrow.

Everything was fine before my "cleaning process." I also strongly suspect that after such a long period of inactivity (2-3 weeks), all the pipes are now empty.

I will provide further updates.

Thank you very much and best regards.
Claudy.

Does the engine have a VP44 injection pump? If so, there's nothing to adjust unless you remove the pump or tamper with its drive mechanism.

Unfortunately, the VP44 is very sensitive when it runs empty and then attempts are made to start the engine. The pump can be damaged in this process.

What type of fuel injection system does that car have?

Best regards, Rainer.

Hi Rainer.

Thank you.

I just came out of the garage.

1. Ja, das mit der leeren ESP ist bekannt, bei meiner Druckprüfung an den Düsen kam immer Diesel heraus. Jetzt habe ich alles (hoffentlich) wieder voll aufgefüllt. Die Ansaugleitung zur ESP zieht auch gut Diesel beim Starten. Ich warte noch bis meine Standheizung gleich den Motor vorgewärmt hat und dann .... Hofpublic?

2. The fuel injection pump is likely an original OPEL part (2 photos) with the Opel part number.

I'm going back to the garage now, and I'm not giving up hope. Once I understand how the (rabbit) Astra works, I think I'll be able to figure it out - with your help!!! javascript:emoticon('')

I enjoy tinkering with our "fleet" of vehicles. However, a diesel engine hasn't yet come into my hands for me to work on.

Thank you again.
Best regards, Karl.

Opel does not manufacture fuel injection pumps.

YES!

Furthermore: If there is absolutely no air left, the error MUST be fixable; otherwise, something has been adjusted on the ESP, or the ESP is now defective.
