Of course, I have never had to call Germany to ask for help, I am positive that whatever technical knowledge they imparted on you makes you far more knowledgeable that I will ever be, so far I have managed to sort out all the issues on my Corsa by myself.
 
Hi.i have a 2002 Corsa bakkie.that runs out of fuel just above quarter tank.any suggestions on how to solve it.there is fuel and the gauge is working.

Sounds like your fuel level float or sensor is borked.

Sounds like a clogged fuel line then. Check the line and fuel filter.

I have a new filter on.car runs perfect when tank is full.its only when it's below half.i have a pirate fuel pump and gauge on.not sure if that could be the problem.

So when it stops reading how much confidence do you have that there's still fuel in the tank, what if the pirate gauge is misreading?

It sounds like an odd problem.

I drained the tank and there is still a lot of fuel.that is why I think the gauge is ok.

Did you physically compare the two pumps with each other when you removed the real thing? What about calibration? How do you know the pirate pump was/is correctly calibrated for the size of tank installed in your car?

Check all the obvious things, filter, connections, etc

No I didn't.when I removed the tank I saw the pump was modified.so I changed the complete unit.i thought my problems where solved.

Are you sure you got the correct pump? If that pump is too short and does not reach down low enough into the tank, it would not empty it. Or is there a pick-up part or base filter missing.

After much mayhem.. replacing fuel pumps and relay it turns out my inner pulley had turned. Causing timing to move out.
On inspection from outside you cannot see the keyway. You will have to remove the outter pulley aka balancing wheel and check. While down there i changed the crank sensor and oil pressure switch.. all together this costs around R500.00
Pulley 200
Crank Sensor R200
Oil switch R100
Fuel pump (bosch 684 replacement) R250
Leads R150
Coil Pack R550
New Resistor Plugs R160
New V belts x2 R350

The corsa seemingly eats spark plugs.. if you put in non resistor plugs.. so its always a good idea to go with recommended plugs. Bad or incorrect plugs can cause your coil pack to fail.

I also cut out the Cat converter as this causes too much heat causing the starter to crack and the manifold.

Oil was a std SAE40
Brake pads were std at R250
wheel bearings were also replaced both ends.. i got STC for R140 each.. pressing was R100 each.

Currently i am getting around 11 km to a litre.
These cars are fitted with various different computer boxes.. THESE UNITS DO NOT BREAK. BEWARE OF BEING CARRIED AWAY BY UNNECESSARY DIAGNOSTIC TESTS.
in most of my issues.. an ODB2 machine could not find any faults. But ran a scan wasting me R350 each time.

I would like a professional opinion on taking out / removing the thermostat.
In these over head cam opel engines.. there's alot of heat. Removing the stat could and will improve temperature but on the long run and long drives.. does this have an effect on the pressure within the coolant system eventually causing pipes and radiators to burst?

That idea of yours is a "misfire". Leave the thermostat in situ to do its job, if the removal was advantageous the manufacturers wouldn't have installed it in the first place.

The thermostat only really plays a part in colder climates and in winter and when starting.
