Hi Guys,
I have just purchased a 2000 model Jackaroo SE with a 4jx1 3.0 engine.
Purchased as a NON starter.
Has not been running for 2 1/2 years.
Got it home and did the following.
New diesel (Drained Tank)
New fuel filter
New Air filter
New Oil - Penrite 5W-40 HPR Diesel 5
New oil filters x 2
New o-rings on both oil pick ups.
Got engine to start and run ok but then would not start hot.
Did some research and decided to clean out the Oil Rail Pressure control valve solenoid and cleaned the Crankshaft speed sensor.
This fixed the hot start drama but it still has a slight miss.
I put tech 2 on it and the ORPS is showing 0.2 MPa with no engine running?
Also when the desired pressure is 4.0 MPa the live data is jumping from 3.9 to 4.9 very quickly.
There are no fault codes logged in the ECM
Click test on injectors sound strong on all four.
Injector cut out test sounds normal (no weak sounding injectors etc.)
I am in 2 minds as what to replace TPS or the ORPS?
Any info much appreciated.
Thanks.
