perhaps the fuel pump has quit working

This can depend on the year of the vehicle, which engine is fitted and the fuel type. The Velociti is also know as the Mk1 Golf, (the later facelift version), and the Rabbit. A workshop manual for any of these will have that information. It is worth getting a manual if you are doing these types of bigger repairs.

most mfg's put them under the dash have never wanted a VW so cannot be sure but wouldn't you think an auto parts store locally would know if you g in and ask them

If it 'cranks' it IS turning over. It is turning over, (cranking) but isn't 'firing' :>) You need to remove a fuel line near the engine firewall and verify the pump is working. You may have burned the pump out as they rely on the fuel for lubrication and cooling. Also check for codes with a scan tool. https://www.google.com/search?q=2000+vw+cabriolet+fuel+system+diagram&safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk03DWp28xQEoml01rV2pInqNX75RDQ:1619470219577&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiA06XZ5JzwAhVZWs0KHZVaBr0Q_AUoAXoECAEQAw&biw=1920&bih=937 ..

ask your local dealer . i have never owned a VW .

Any check engine light? Does it run ok off idle/driving? Check for vacuum leaks like bad cracked loose hoses first.

Did you actually check the power supply to the pump or just assume there is no power because the fuse was ok? If there really is no power in the fuel pump circuit it might be a function of the immobiliser to cut the power until it is disarmed but if there is power, proved by the use of a test lamp, the pump is probably defective. In depth troubleshooting isn't practical without reference to a wiring diagram.

Two choices: take it to an automotive electrician. tell him you have parasitic draw. Or you get an ammeter and put it on the battery. Then you pull one fuse at a time until the draw stops. That purely tells you the circuit is in on. Then you have to find the item.

Removed homophobic word and reworded question On the low right-hand side -- passenger side -- of the transmission you'll see the drain plug. On the front, upper left-hand corner you'll see the fill-check plug. Remove the fill-check plug first with a wrench; if the transmission fluid is up to level, a small amount will trickle out.Jun 12, 2017

Are you sure it wasn't sparking prior to jumping?

There isn't one. The oil light is part of the instrument cluster display, just lights. https://www.cargurus.com/Cars/Discussion-c5879_ds625764

A memory saver when changing the battery is a good idea and helps avoid such problems. The most likely cause of the problem is the vehicle immobiliser...

It would have been useful to know where the hose from the tee goes and what diameter as that is new to me. 50 years as a repairer and I have never seen a top radiator hose with a tee branch. Usually the engine heats and the thermostat opens and starts coolant circulating through the radiator, up the bottom hose into the water pump to be pushed round again. The volume of coolant moved by the water pump, even at idle should be far in excess of that circulating through the heater matrix ensuring adequate circulation through the radiator as soon as the thermostat opens. The top hose must be hot because the thermostat is open so why doesn't the coolant go further and heat either the branch or the rest of the hose and radiator... Sometimes a pump with a plastic impeller will lose a vane and overheating due to insufficient circulation is likely. Other things are more common - semi-blocked radiator tubes restricting coolant flow. Silt build up in the cylinder block causing hot spots in the cylinder walls. Restricted air flow through the radiator. Electric coolant fan not working. Excess combustion gas in the cooling system interfering with thermostat operation. Degassing system blocked with the same result.

Handbook supplied with the vehicle is the most reliable source of fusebox specs. Repair manuals and other sources tend to provide aggregate information barely allowing for changes made due to territory and trim level.
