1060.0. "Help - Injection Problems on Astra" by RDGE13::MADGE () Wed May 02 1990 17:06

    
    Hello all,
    
    As my knowledge about cars is fairly limited I was hoping you could
    help.
    
    I am the owner of an Astra GTE and about two weeks ago - I accidently
    let it run out of petrol. Ever since this happened the car has been
    coughing and spluttering, especially when accelerating. But even at
    tickover the car runs slightly under revs. I run it on Unleaded petrol 
    (when I run it on petrol at all, that is). And have tried changing back 
    to leaded, put in the new higher performance petrol from Shell, you 
    name it, I have tried it. Petrol comsumption also has increased.
    
    I have been informed that the problem could well be in the injection
    system itself.  Is that at all possible ?? Surely if the injection was
    blocked it would not run at all, would it ?? Could it not just be the
    Fuel filter has been clogged by the dirt pulled up from the bottom of
    the tank ?  Stopping the fuel getting through ?
    
    I don't really know which is the better Idea - whether to take it
    straight to Vauxhall or get a Fuel filter first and see what happens.
    The filter is about 17-00 to buy
    
    Has this ever happened to you ??  How did you get it cured...
    
    Thanks for any help you can give.

	The clogged filter is an obvious possibility, the other is
	an air lock. Maybe there's a vent screw somewhere?

1060.2Fuel FilterIOSG::MARSHALLWed May 02 1990 19:3210
If the fuel filter's transparent, you should be able to see if fuel is getting
that far, which would rule out an air-lock further back down the pipe.  You 
hould also be able to see if fuel is getting through it, or if it's bunged up.
Clean it with fresh petrol anyway and put it back.

My brother had a similar problem after running out of petrol.  It turned out
to be gunge blocking up the fuel pump.  This is easy to clean out yourself, if
you want to try a home-remedy before paying Vauxhall lots of money.

In my experience the fuel fliter is very easy to clog on a GTE. Maybe it is 
something to do with it's location under the car at the rear!
When I owned a GTE I had the same problem, a new filter cured it.

    Agree with .-1 :-
    
    The fuel filter is probably a throw-away type - on my XR (also
    Bosch injection) it was an aluminium-ish cylinder about the size of a bean
    tin, with input and output connections in the opposite ends.
    
    btw: The filter should be replaced regularly anyway - 18000 miles on
    XR's - anyone know what it is for GTEs?
    
    I also drove an Astra SRi (similar, but not identical Bosch system),
    and ran it out of fuel on two occasions (why don't Vauxhall fit a low-fuel
    warning light???). I had no problems on re-fuelling.
    
    The air-lock problems in FI systems are supposed to be a thing of the
    past. Even modern diesels are reputed to be self-venting.
    
    So I'd replace the fuel filter first. Watch out for the jet of petrol
    that will squirt out when you undo the couplings and release the
    pressure in the system - around 60 psi! (Murphy's Law says it'll get you
    right between the eyes even if you're looking the other way. :-)

Yes it is.

Same, every 18,000 miles (unless you run out of petrol).
    
>(why don't Vauxhall fit a low-fuel warning light???). 

They do in the GTE, the LCD fuel gauge flashs when low.

1060.7They do on the SRi tooMARVIN::RUSLINGMicroServer Phase V Session ControlThu May 03 1990 15:364
They fit a low petrol warning light on the SRi now, the old model didn't have
one.

1060.8Fuel filterCHEFS::MADGEJThu May 03 1990 20:3914
    Well thanks a lot for all your inputs - I have been out and purchased
    a new filter - your quite right, it's aluminium type about size on
    bean tin...                     
    
    I admit the low petrol light was flashing at the time - all my fault
    !! The car did try to warn me..
    
    I hope the new filter does the trick anyway !!
    
    Thanks again.

    I had similar problems when I let my car run out of fuel. A new filter
    did the trick.
    
    In the manual, it tells you to run the starter continuously for at
    least 40 seconds before trying to start it.

1060.10VOGON::ATWALDreams, they complicate my lifeThu May 03 1990 21:095
    how can you run the starter for 40 secs without it starting?
    
    (says that in my manual too)
    
    ...art

    ...pull the LT off the coil (or similar).

  Mark
1060.12TASTY::JEFFERYIs "Bones" the real McCoy ??Wed May 09 1990 14:287
    Thats what I thought, but the engine was on the starter for 40 seconds
    with no sign that the engine was actually started and killing the
    starter motor.
    
    They don't say anything about removing lt leads or anything.

1060.14Crush washersIOSG::MARSHALLWed May 09 1990 15:435
But repeatedly removing and replacing plugs will damage the crush washers and
so you'll get leaks around the plugs, and hence lose compression when you don't
want to!

>>want to!
    
    depends on how long you intend to keep the same set of spark plugs!
    
1060.16Getting fed up of CARS!PEKING::SHALLOMAMon Dec 07 1992 17:0219
    
    Hi,
     
    I have a problem with my car at the momment, similar to that of
    note .0 in this topic....
    
    Can anyone reccomend any mobile tune up service wich cater for fuel
    injected systems. (Its a Manta 2.0i) or know what could be wrong?
    
    p.s. The main problem at the momment is that now and again the car sort
    of cuts out momentarily and then picks up power and again,but it also
    stalls sometimes and is very dificult geting it started again..It
    fires up ok but then cuts out staight away....and then eventually its ok
    to drive until the routine stats all over again....
    
    
                  Regards,
                              Aron...
