The ECU will be fine with a engine rebuild but the 4JX takes a bit longer to start if all the injector oil paths are empty - can be up to 5 or 6 mins of 20 second cranking bursts.
Also if you rebuilt due to diesel in the oil from bad injectors the control valve for the injector oil pressure may be faulty so it wont start.

Sorry for the severe delay.
I am personally going back to answer your unanswered question.
I do not know if you still need the answer, but I am going to answer it in case you still do.
Click on the following direct Link. It has the Timing Belt Diagrams and Photos with Marks for the Camshaft and Crankshaft that you will need. It also has numerous other helpful diagrams, instructions and photo's for use.
Again my apologies...
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

Sends a signal related to the rail pressure as a voltage to the ECM. 3 wire connector :
Low pressure will set P1194 error code. Oil rail pressure should be more than 3MPa when cranking
Also check Engine coolant temp sensor and wiring. Engine coolant to manifold temp should not differ by more than 5 deg C either way after 8 hours of no operation. I have found the same symptom on these diesels with fuel supply problems. Operate the priming pump (on top of the fuel filter) until it becomes diffycult to push down before starting or checking anything else.
Testimonial: "Thanks Suzman, We actually managed to get it going....The only problem remaining is a rough idle until its warmed up and sometimes stalls until warm. "

the timming gear that the belt runs on has a mark (V cut in gear) to rear cover at about 12 o clock and crank pulley has timming mark for top dead centre, both cams have cut outs in rear that a special tool (camshaft stopper 5-8840-2592-0) locks into to hold cams in correct position, but can do without this, if the cam belt gear is off, the keyway should be at 12 o clock. the marks in the camshaft gears (dots) is for assembly of sissor gears to solid gears on camshafts that run together and they should match up only if you had this appart.
no.1 is timming mark
this is the locking plate tool

you need to set the timing to top dead centre and the flywheel has a little knotch in it set that at 6 oclock will start then
