Hi,

 

I have a 2001 CV220 2.2

 

I've posted about this before, but despite several attempts to repair it the problem persists. The symptoms are, when the car gets warm, its cuts out as if it has ran out of fuel and wont start. If you leave it till it cools, it starts perfectly and cuts out again as soon as it reaches temperature.

 

The car has been lying in Vauxhall for the last year who have diagnosed a faulty fuel pump. I purchased one from Glencoe Ltd. This resulted in very slightly better performance when the tank was full, but the same problem persists.

 

The issue I have is Vauxhall have identified this as a faulty fuel pump issue. It seems unlikely the pump would fail, followed by the new replacement also failing, and I dont want to have to go to the added costs of taking the pump out, returning it and having to reinstall it to find out it was never the fuel pump.

 

Prior to the fuel issue there was a series of electrical faults. The car hit a bump and several things happened: The windscreen wiper stopped working (requiring a new motor at a ridiculous cost). The ABS failed requiring a new sensor. The speedo stopped working needing reconnection. And the fuel issue started. 

 

Does anyone have any ideas on what could be the issue? As it has already cost thousands and I cant keep paying mechanics to experiment with solutions.

 

Thanks.

If it only works when cold I would guess a dry electrical connection somewhere? What about immobiliser?

[fezzasus]

Switching to EGR could be causing a fault (bridged to ground). Would recommend replacing the valve or cheater

[gaffer1986]

Good point. Trying a chapter first should cost next to nothing?

RPM sensor going open circuit when warm - had that on a number of cars before.

When it wont start is there fuel present at the pipes ?

[Johnboyhgt]

Only 4 things stop an engine running 

 

1 no fuel

2 no spark

3 no air 

4 no compression

Only problem is that a thousand and one things cause those four problems!

Hi, Yes. you can smell the unburnt fuel. It doesnt fire at all, not even a rumble

agree but i have lost count the amount of times it gets overlooked.

you might be able to smell it but is there fuel definitely at the engine pipes ?

 

also does the fuel pump prime up ? it should do a 3 second burst when you turn the ignition key on.

[gaffer1986]

Don't envy your problem, however I would stay away from Vauxhall. This forum is probably your best bet to solving the issue. Do you know who Vocky is? I highly recommend him as he knows the NA engine inside out.. Literally.

[St3v3boy]

Does anyone happen to have a wiring diagram for the car? The hanks for the suggestions, I'm going to check them out and see if there's fuel at the engine.

[chris_uk]

there is a little plastic cap on one of the fuel pipes, remove that and you should see a valve.. put a rag under it and slowly push it in, fuel should come out, once there is none left release it and turn your ignition on and see if it has re-pressured the pipe, if it does whip off the coil pack and crank it... take out the sparks and see if there is unburnt fuel on the spark plugs, or see if you can see any in the cylinders..

 

i had a similar problem on a VXT and it turned out to be the ecu, although there was fuel getting to the injectors the ecu refused to fire them when it was hot.if you started it from cold on a morning it would run as long as you wanted. turn it off and back on.. and it refused to start. 

 

took me a while to find lol

loads of similar symptoms on the web for vauxhall 2.2 engines.

 

mention fuel pressure regulator and as chris said the ECU

What he said!  Had this on a Subaru and it turned out to be a dry connection in the immobiliser.  When the car was running and the immobiliser got warm the PCB inside the immobiliser moved slightly and cut the power, when it cooled down everything worked again.  Cost me a fuel pump though before the penny dropped. 

[vocky]

certainly worth trying another coilpack, try and borrow one from another member for testing.

 

Blank off the EGR valve, leave it swivelled over the side.

 

Might also be a dodgy fuel pump relay in the boot, try swapping the grey relay with one from under the front bonnet and you will need to borrow a brown relay to test that.

Ignition Coilpack

 

 

[Ormes]

Crank (and Cam) Sensor would typically allow the car to turn over but not start... maybe the sensor(s) has had it, or the wiring is broken.
