Hmm got it back together bar topping up the coolant. Unfortunately no joy. Spins over sounding like it has very little compression but feels like loads when you turn it over by hand.

Top end strip I guess?

so i didnt get lucky

Any Fault codes and live values for the Fuel Rail

I dont have a reader to assess fault codes unfortunately. When the AA man checked the fuel pressure values it was bouncing around 270bar which I guess is OK.

One thing did occur to me during a sleepless night. Could I have got the crank 360 degrees out so that the engine is trying to fire on the exhaust stroke rather than the compression stroke? Bearing in mind that the timing had slipped so I just moved everything until I could get the pins in? Or to put it another way is the cam timing 180 out of position?

The fact that it didint attempt to fire at all on any cylinder makes me believe something else may also be amiss

Gary

Just had a look through the forum and it would appear that the cam timing cannot be 180 out. I guess the injector timing is controlled by the cam position sensor?


I was thinking about older diesels with mechanical pumps and petrol engines with distributor ignition timing where such an issue could occur i guess.

so back to the drawing board. Can anyone recommend a reasonably priced code scanning tool? Are the bluetooth ones any good?

my love for this vehicle is starting to wane

Yeah thanks I figured this out . Its something I thought up whilst struggling to sleep last night so not completely thought through . Please see my next post on the subject.

I guess I am back to a top end strip

AP200 the white one is an almost giveaway price

This?

https://www.ebay.co.uk/itm/116077472256?

Yes and it's a good price too

Item purchased. Should get it by Friday.

I am of the opinion that as I have good compression on all cylinders that some of the rocker arms/cam followers call them what you will have snapped. Apparently they are prone for this according to a number of sources?

Gary

Ok AP200 received configured and connected. Cool piece of kit thanks for the recommendation

error codes before I cleared them

Diesel air flow control - open circuit
Diesel air flow position sensor - circuit high
Camshaft position sensor - circuit range/performance (bank 1 or single sensor)

after I cleared them and spun the engine over

Diesel intake air flow control - open circuit

fuel rail pressure 4500 PSI

Here are some readings from mine

Some Live value readings for fuel rail pressure
Cold Outside Temp is -1degC
last used yesterday afternoon Jan 2022

340 Bar before switching on

Tickover 430 Bar
2000 Revs 810 Bar
This reader a Foxwell 510 also gives voltage readings
Fuel Rail Temperature Sensor voltage
Cold 3.31 Volts
Tickover 3.13 Volts
2000 revs 3 volts
Fuel Rail Pressure Sensor voltage
Cold 0.5 Volts
Tickover 1.37 Volts
2000 Revs 2.19 volts

So I am getting about 310 bar just spinning the engine over this did spike up and down so fairly similar to your 340bar figure. Are you saying my pressures are too low? Obviously I cannot give you running figures as it wont start.

I have already had the throttle body off when I removed the starter motor to redo the cam belt. The throttle assembly was quite gummed up but still seemed to move ok without jamming. I have not had it apart to check for stripped gears but from what I have read most vehicles will still run if this part is fauly unless i guess if it is jammed shut.

so still at a loss as to what the problem is. I guess the rocker cover needs to come off. I have compression on all cylinders but that does not mean to say i dont have any broken cam followers.

Any thoughts?

Your help is very much appreciated

Gary

No not saying your readings are bad in fact looks like your pressure is fine. I am not saying my readings are good either just put up for information
If I were in your situation I would go back to basics rather than doing a strip down and start with say the Crank sensor check the connector, Is it cranking on the starter. Looks like fuel pressure is OK. Maybe unplug the MAP to see if it will run in closed loop.

OK thanks will check RPM readings when cranking to see if the crank sensor is working OK. MAP sensor was bunged up with gunge when i removed it (i cleaned it) so will try this disconnected also.

The AA guy did say when we spun the engine over when it first failed that there was no suction from the intake hose when you put your hand over it (disconnected from the air filter) but this was when the timing was out.

This will not be until tomorrow as my wife would like to go shopping today

cheers
