toyota spacio 1998 The "Spacio" nameplate was only used in Japan! are you in Japan speaking English?
cranks ok

my wild guess is FUSES blown. we check them all, open mind.
scan the PCm and TCM to see if there are transmission errors
the car needs service, find a shop and schedule it.

what are you attempting to do , not told

A vehicle with an automatic gear box cannot be towed without severe damage to the gear box, because there is no oil flow in the gear box unless the engine is driving it.
Look for a replacement gearbox.

The Spacio has been recalled several times in different countries for various reasons, including faults in steering shafts, airbags, and emissions systems.

Find your vehicle's VIN or chassis number on a plate on the firewall, and then contact your nearest Toyota dealer for information. They will have a huge database on this. In most countries they are not permitted to charge you money for this answer.

i doubt very much if it would be running at 1 litre per 1 kilometer
at very rich combustion stops at 10:1 as the fuel puts he fire out
I'm not disputing your figures just I would be looking for a fuel leak from a hose , filter leak or leak in the tank or some one stealing fuel
run the fault codes
check the fuel system from tank to manifold

Write your answer...may be 1 ltr. : 18 km.

10 - 12 Km/ltr on local drive
15+ Km on long drive at speed around 90 - 110 Km/h.

Divide 75 kilometers by 7 1/2 liters to get 10 kilometers per liter.

I Don't think it is right either i have a new yorker with the turbo and it doesn't use any oil
