Can i get a mechanical injector pump for 4.2gq

[landy96]

I want a gq without a computer system either petrol or diesel is it possible to buy an injector pump without the electrics .prefer if i could get one to fit my current zd30 so i dont have to swap it for a gq

A TD42 injector pump from a GQ is totally mechanical with no computers or fancy electrical gizmos.
I can't imagine getting it to work for your ZD30 though.

All 4.2 diesel gq are mechanical. So are all gu td42s.

A zd30 pump is even mechanical....

[landy96]

Isnt Zd30 controlled by the computer whats all the wireing coming out of it . And cant the computer make it pump more fuel in making the engine run hotter ?

The pump is still mechanical with some basic electronic functions on it. It will basically only control fuel metering by reference to ecu inputs. Some of those wires are also for the nats (anti theft).

You would have to have significant issues with egt control, power and smoke to be causing water temperatures to rise.

As soon as temp starts to move i stop quickly to let it cool i havnt gone over 3/4 yet

[landy96]

Can these wires be bypassed

[nissannewby]

No. And like the other thread I dont think this is your problem. Happy to be proven wrong.

If it was fuel causing your issues then you would have the problems I stated in post #5.

Possibly you have already made your mind up about what to do with the vehicle and you are hoping for an answer that you want to hear? If this is the case then move the vehicle on and buy a TD42 GQ wagon (which wont be a ti or auto), with no electronics.

So if theres no smoke theres no extra fuel
So if its not fuel what else might cause it to jump up so quickly .im talking 100 200metres up the range .its not gradual Like a mechanical thing its more instant like a switch going on.Weather i keep it or sell it i have to fix it .

So your having over temp issues and trying to problem solve?.
