Hi mate. Hows it going?

A quick one....from VIDA, looking from exhaust side, Cylinder 1 is the 1st one from left hand side (= 5th one looking from intake side)?

And should I turn the crank pulley or the flywheel counter clockwise?

Crankshaft counter-clockwise ( Viewed from rear ) = Crankshaft clockwise ( Viewed from front ). Because your your left and right flips in relation to the engine when you turn around.

(
Looking at the back of the engine the intake is on your left,
Looking at the front of the engine the intake is on your right.
Because you turned around.
Same thing with clockwise and counter-clockwise.
)

Another way to look at it. From either end you move the top of the crankshaft toward the intake.

Cylinder number one is on the right hand side of the car, driver side for you.

Cylinder five is left hand side of car, passenger side for you.

Thanks for your replies Rick and abscate

It all makes sense now. I didn't actually realise that VIDA is referring to longitudinal engine layout whereas in my car its in transverse...So intake is towards the front.

Completed the timing and it still wouldn't start. High pressure pump is getting diesel but diesel is not coming out of the pump to common rail. Would it be a bad idea to use like 5 cans of Easy Start and let the engine run on that for a couple of minutes to see if pump builds enough fuel pressure for injectors?

Thanks again

No matter how a engine is mounted. Cylinder #1 is always on the end where the crankshaft pulley is.

I disconnected fuel inlet pipe from the high pressure pump and connected that to a clear hose then to a container. With key position II fuel flows steadily and as soon as I ran the engine, flow stopped and it wouldn't then flow at all, even after turning off and on back to position II straight away. I then waited for 5 mins and turned key on...fuel flows

Did another test by putting the clear pipe on the inlet of the engine fuel pump with the fuel container, to check see if it can suck up the fuel direct from the container. Nope, its not pulling up the fuel from the container. I even raised it to increase the gravity but no.

Any thoughts?

Thanks

Evening. Hope you guys having a great weekend.

I'm sorry I will have to seek more help from you. Car still wouldn't start. So I thought I'd start over again...Took camshafts out and ready to install them back and do the timing. Before doing that I want to double check the process....If I remember correctly, I did set camshaft sprocket to timing marking and then removed it but lets say I removed timing belt and camshaft without setting to timing mark and this messed up the timing.

So would the timing set to be OK if I install everything back to following order?
(with timing belt and camshafts being out of the head block)
1. Setting crankshaft timing - turning crank pulley anti-clockwise until stopped my the alignment tool behind the starter motor
2. Installing camshafts and do the locking behind vacuum pump
3. Fitting back the camshaft timing belt sprocket to the marking on the cover

Thank you

Thank you mate but no luck with that either.

I also removed all fuel system related connections (except the pump) and tried to start the car - it threw loads of codes. Connected back, cleared the codes. Car didn't start but no more codes. By this can we confirm all the sensors and valves are electrically working?

Tomorrow I'm going to check the fuel pump under the rear passenger seat. I'm going to check connection voltage but should I do a particular test on this or I have Delphi scanner....Could I use the scanner for testing the pump and other parts?

So..from today's test, flow control valve is working to 12v battery connection. I checked the voltage on the connector is reading around 8V. Diesel also flowing sharply to the valve - please check the video I have uploaded on YT:



I think I should take the pump and, dissemble it and check for blocks and worn seals?

Oh and...when I was cranking I checked the rev meter on dashboard and it wouldn't move at all. My understanding is when crankshaft is rotating, rev should move?
