Hi Guys, I have a Zafira 05 SRI 2.2 petrol. When I accelerate I get a rasping noise the engine or exhaust sounds like a motorbike particularly at 2000 RPM. It also feels lumpy and when accelerating I feel as if the vehichle is being pushed back poor acceleration. No lights have come on the...

Hi Andy I had this problem and it was the fuel pump the one located in the engine compartment. I replaced the siemens fuel pump with a continental one as the Siemens pumps are defective. I bought it off ebay for a fraction of the price the main dealer was charging. It is a straight forward job...

Hi Everyone I need some help, my Zafira has a ticking noise which has been there for the past year and is now starting to annoy me. I took a video so you can hear the noise. It is coming from the alternator area.

Received new Continental HP Fuel Pump today from Choice Car Parts (£275.00). Fitted the pump, ran the engine for a while to get pressure back in the engine and I am back on the road. It feels like a new car, my 2.2 SRI it has its vroom back, it feels like a new car. When I removed the old pump...

Evocarlos I will let you know and I want to thank you for all your help. The only thing I could not test was the sensor. I did not have a manometer to test the pump pressure manually. But I am going off the desired and actual fuel pressure readings. Thank you once again. Mike

Well guys just to put this to bed I have ordered a fuel pump from Choice Car Parts it is coming tomorrow so hopefully it will resolve the issues.

Evocarlos Just tested the Zafira on the OP Com and these are some of the readings. Desired Fuel Pressure - 7000Kpa Fuel Pressure Feedback - 380Kpa Fuel Pressure volt at 3000rpm fluctuates between 0.6v and 0.7v Fuel relay active okay Fuses ok I think the Siemens Fuel Pump has gone.

Jordy The full code from the OP COM is P1191-52 then we cleared it. Then it showed P1191-5a fuel sensor low input.

Evocarlos Thanks for all your help. Going to get Op Com on today and will you know. Thanks once again. Mike

Evocarlos thanks for the info. Can I assume that from the diagram that as my Zafira goes into Limp Mode and is still driveable then the regulator is defective? I am confused because this section of info indicates my fuel pump may be defective as the high pressure fuel rail on mine is 380pka...

My Zafira 2.2 (Z22YH Enginge) 05 plate Petrol went into limp mode and the amber spanner light came on. The RAC diagnosed a code P1191 Low Pressure Fuel input Sensor. My local garage have had it for 13 days now and still have not been able to diagnose the problem. When I called in to check on...

Jordy thanks for your reply. I am very tempted just to buy a continental fuel pump for £280, but if it is not that then I am back to square 1 and £280 out of pocket. Just out of curiosity did you need put it on a tech 2 machine once the pump had been fitted? or did the engine just rectify...

Rushy did what you suggested and drove the zafira upto 5000rpm it stuttered and went into limp mode. Cannot yet provide the code but suspect it will be p1191 as spanner light came on. Do you think it's the fuel pump? Thank you.

Hi Rushy, Thanks for the info. I will try in the morning and post the result. The garage think that because the fault code states the word input (Low Pressure Fuel Input) it means it is an electrical fault or the sensor is faulty. They are not sure how it has come out of limp mode and running...

Rushy Thanks for your reply. I have revved it up to 5K and it seems and driven it at 3.5k and it is fine. What will putting the engine under load do?

Hi and thanks for the replies to date. I went to the garage today to find the car was running fine. It was not in Limp mode and no lights were on the dashboard. The engine was running fine and the garage have not done anything to it. They think it may be a sensor but they are not sure. Can...

Evocarlos I have read that thread and posted on it also but no on has responded. I was wanting a clear direction on what is broken. Is it the regulator or the pump? I need a clear diagnosis.

I really hope someone can help me. My Zafira 2.2 (Z22YH Enginge) Petrol went into limp mode and the amber spanner light came on. The RAC diagnosed a code P1191 Low Pressure Fuel input Sensor. My local garage have had it for 3 days now and still have not been able to diagnose the problem. When I...

My Zafira 2.2 sri petrol (Z22YH engine) is in the garage and was diagnosed with a Swirl Valve Malfunction code p1112. After stripping the inlet manifold down it appears the Swirl Valve Actuator Motor is not working swirl flaps don't appear to be damaged or jammed. How much is a new Actuator...
