Hilux KZTE low on power
Posted: Mon Jun 05, 2017 8:14 am
Morning gents
I recently purchased a 2001 Hilux 3.0 KZTE 4x4
The person i bought it from told me the bakkie overheated and a resulted he overhauled the motor. Replaced, mains, big ends, pistons, head, injectors etc..
However the bakkie then went into "limp mode" and was down on power and starting building pressure in the cooling system, causing the radiator hoses to swell.
Anyways, i bought the bakkie as i got it for a steal and was sure i could fix the problems.
I found that the reason for the cooling system building pressure was due to the heater core being block. I then bypassed the heater core and the bakkie has no issues with overheating or swelling radiator hoses. Problem sorted.
Now, the issue with the bakkie in "limp mode"..No boost, would not rev up and dead donkey slow. I sent the bakkie to an auto electrician who found a Unichip on the bakkie which i instructed him to remove (im more of a factory standard type of guy). The bakkie ws still in limp mode. We then plugged in the dianostic tool and it through out error code 14. I researched error code 14 and found a host of problems which could lead to this code being kicked out by the ECU.
We suspected it was the diesel pump, but before jumping into the deep end and spending 15k to overhaul the pump i decided to rule out any other issues which could cause the error code.
I checked the crank angle sensor on the diesel pump and found that one of the plugs was in a bad shape. I repaired it and the light went off. Bakkie is now boosting okay, but still does not have the power which my other KZTE has.
So my question is..
What else could be causing the bakkie to be low on power?
Can it be fuel pressure related? Is there a way that fuel pressure could be turned up? If so, are there any repercussions if the fuel pressure is turned up?
Have i overlooked anything?
Is it possible to clean the injectors with injector cleaner thrown into the tank?
Im trying to rule out any other possibilities before i go ahead and replace/overhaul the very expensive diesel pump.
Help will be appreciated
