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

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.

Sends a signal related to the rail pressure as a voltage to the ECM. 3 wire connector :
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. "
