DEAD ZD30 to TD42T swap

[robewott]

do the engine mounts have to be changed much? are there any problems with registering to vehicle?

Hello,
I'm not going to open a new tread because I've got exactly the same situation - dead ZD30 and a brand "new" TD42Ti engine without ECU available. The difference is that in Poland those engines are very rare so availability of used parts is not very high.

Could you guys advice which way of sorting the problem of pump is the easiest? Is it possible to buy ECU anywhere?

anyone can pay a little attention please? on another forum i've read something about converting electric/electronic pump into fully mechanical by replacinf the head. is that solution posible? if yes - is it expensive? and are the parts available easily or i should for it next half a year?

The td42 has a mechanical fuel pump which runs off gears from the crank, the same way the valve cam does.

So any aftermarket or electronic fuel pump won't be needed to supply the motor.
You just need to join main pickup line to the pump via a fuel filter.

As for ecu I'm unsure. I don't thing the td42 needs one as it's all mechanical and vacuum.
Unless you guys have a different newer variant over there? Here in aus they stopped importing the td42 due to emmision controls nearly 10 years ago..

So is a TD42ti electronic pump ?
I'm just starting to learn about 42s my self, so I'll be keeping threads like this under close watch.

I believe the TD42TI has a semi-electronic pump.

The latest TD42Ti's had a small amount of electronics. These are the td42's that came factory turbo and intercooled. Using a couple of sensors and inputs there is internal timing control of the injector pump obviously dependant on the said inputs. These engines also had a basic egr setup on them as well which utilizes the same ecu for the pump control.

They had electronics from late 03 to there aus demise in 06.

Hi,

this is what I already read on this formu. We call it a semi electronic pump or whatever. What I understand is that to propoer functioning this pump needs to be connected to the ECU. Now my question is - what are the options to make it work. What was writen in different threads - the best would be to replace the pump to the one from TD42T. Are there any other options?

thanks
