Thread: 2.8 hilux injector pump fitted to 1kzte

The Fuel shut off/spill valves are on the pumps so unless your unlucky and both are faulty...
The 1KZ has a throttle plate (the one you have wired open?) They help with a smooth quick shut down also for EGR operation I believe. They can be removed and they still shut down quickly just with more of a jolt.. But with it wired open and possibly leaky injectors its able to run on I guess, no doubt the injectors have done plenty of KS
Have you checked the intake pipe and manifold? They get well blocked up with crud!
Check all fuel lines and Primer for leaks.
Have you checked if heads cracked?

Best put an EGT gauge on there, don't want to much fuel/heat going in... or you'll be replacing the head soon if its not all ready cracked...
Intercooler is a good idea if putting in more fuel.

To be fair the factory 1kz pumps are fine, you can tweak the fuel a little on the 1kz spill valves for a little more power, 1KZ have a boost cut 14psi think it was. can get boxes/chips to get rid of it...
