yep that's exactly what i've done

atleast i know i've got my timing done right

i will check for a CEL tomorrow

thanks guys

Hey man,
Check the CEL, find out what code you have but also do the following.

Pull cyl 1 spark plug out and rotate the engine anti-clockwise until you see the crank pulley notch about to line up, use a torch to look down inside cyl 1 and you will see piston coming up towards you. Piston 1 will reach top of travel when crank pulley lines up with the notch.

Confirm that camshaft gear has the 2 horizontal spokes lining up with top of the head and that notch at 8o'clock position is lined up with pointer. If so, the crankshaft & camshaft are in synchronisation

Remove distributor cap at this point and confirm that rotor button metal face is facing towards the back of your car so that it will line up with cylinder 1 spark plug lead. IF it facing Cylinder 4, you will need to rotate the slotted gear 180 dgrees as previously discussed, so that the rotor button is facing cylinder 1. I have noticed some people re-assemble the distributor wrong when they pull them apart.

Once you have confirmed all this, I would suspect wiring, sensors or ECU. The pic of your TPS sensor you sent me is really bad and I doubt it would do you much good.

Hangon, I just realised what the problem is! I will be on MSN when you finish work man, so I can send some pics to you.

For everyone else, the Australian Si wiring harness is being used with the VTi(P28) ECU but on the Jap D15B VTEC motor... What ECU signal is missing that would prevent the motor from starting? Clue: VTi has 4 wires, the EG D15B VTEC has 1 wire...

hmm so the d16z6 has a 4 wire o2 sensor?

hmmm

and d15b only 1 wire.....

engine will start without a o2 sensor attached...

oh ok

so it wouldn't even matter if my ecu is for an engine with a 4wire o2 sensor and my engine harness is for a 1 wire sensor?

not, unless the engine wiring harness sent the wrong wires to the ECU as a result of this difference.

i do not have wiring diargrams for D15B so can't tell you for sure... but i would guess that they use the same ECU pin-outs on all EG Civics...

so i dotn think it would be a issue to start teh car.

YOU NEED to check the CEL - this is the best way to diagnose a fault with the engine (or ECU)...

maybe u hooked up your ECU wires wrong

yeh i definately - i'll do that as soon as i get home from work

so ground d4...

and with a small light bulb. feed 12v to one and and the CEL pin on the ecu?

could u be anymore specific?


i tested the necessities for startup.

ie. injectors getting voltage while cranking

relay feeding 12v out of all it's pins (bar 1 AFAIK)

pump getting 12v


it could be the tps - the plastic cover has broken but the inside still looks intact

the CEL should reveal all

ok i found my pulley and from what u said u did it correct
the line that is in front of the three should be directly in the middle of the mark on the plastic cover for Top Dead Cented and the cam pulley horisontal to the valve cover

allways set ur cam timing this way and dont move it forward or backward
the teeth on the belt should slot in and fine tuning is not nessecary

how did u go about the fuel lines?
maybe they aint hooked up right.

read my previous posts man

fuel is fine
