Why won't my classic Volkswagen Polo start?

I have inherited a Mk2 Volkswagen Polo with only 2300 miles on the clock. However, it won't start, the plugs are sparking but there's no fuel getting to the throttle body.

I've changed the fuel filter and the lift pump in the fuel tank. I have also tested the relay and checked the fuse, but there is no voltage to the fuel pump under the tank. Could the ECU be at fault ?

Nothing to do the the ECU. Your lifter pump isn't working. Check the earths to the lifter pump relay and the lifter pump itself. Assuming you achieve voltage to the pump, then if it still doesn't work it could be due to rust inside the tank.

I have a 1969 Volkswagen Type 2 campervan. It starts as sweet as a nut when it's cold, but once it's warm it struggles to tick over. Once running, it's fine. Any ideas what the problem is?
