307 2.0 HDI WONT START

[rd070707]

hi guys, new here and in major need of help

so the story goes, 307 2.0 hdi 110 2002, fanbelt frayed and got caught around crankshaft pulley. Timing slipped and result was mechainc sent head to be repaired and new belts fitted. BUT the car wont start.

crank sensor has been changed, cam sensor reset, fuel pressure high enough on planet, bsi reset. car turns over but wont fire. now looking towards rechecking valve timing and wiring.

any ideas would be really appreciated

No rockers broken ?

I'd check that next as these units snap rockers rather than do the "cam-o-three" thing.

see the mechanic sent the head away for repair claiming there was bent valves although i have heard that only rocker arms break? but now the head is deemed repaired and put back on.

[spider]

Missed that

The pump does not need timing itself, check carefully that the cam / crank are where they should be I wonder if its out a tooth on the cam.

I've dealt with loads of 2.0 HDi's with brocken/jumped timing belts I've never seen one bend a valve yet, as said above the rockers usually break first.
Is planet showing cam & crank syncronisation as being ok ? has the woodruff key sheared on the cam pulley ? does it fire on a sniff of easy start ? If it doesent fire with a sniff of easy start then there is likely no compression.

[rd070707]

yes pp2000 says it has cam crank sync. and i read up on the internet and heard many people say these dont bend valves but the mechanic said it did so so the head was repaired and a new timing belt put on. and it did fire with a touch of easy start so the mechanic believed it to be electronic eg wiring rather than mechanical

The 307 is a swine for loosing its BSI coding if the battery has been disconnected for a while. You should get it on pp to see if this has happened.

[rd070707]

i will be getting it on planet again very soon. how would i know if the bsi has been wiped? i still suspect mechanical issues though, valve timing, and battery doesnt last long so maybe starter drawing too much current?

[Lighty]

Starter could be thebprob, but if it runs on a squirt of brake cleaner, then normal fuel system wold take over once it fired.
Once on the planet, go into the BSI, and into identification, it should have the vin no, and the type of vehicle etc, if it has lost its memory, the id wll be all question marks. Yu will need to re enter the vin and all other configurations. Then you will need to reprogram the keys , this will require the transponder code. It's is easy once you have done it, but difficult 1st time.

thanks il check that. need to check timing like spider says but i dont know how to do it

You need to remove the cam pulley and check the keyway, but tbh the cam and crank synchronisation wouldn't show if it was out, so I wouldn't bother at this stage .wouldhave thought his would have been off when the head was done.

[rd070707]

has anyone got an easy method to check the timing? or can this be ruled out because it ran on easy start? also the fully charged battery doesnt last many turns, so how do i test the starter isnt drawing more current than it should??

[Lighty]

As I said if it runs on brake cleaner or easy start, then the timing will be ok.
Also it won't be the starter, as it would run on its own once it fired on the substitute fuel.
I would say its 90% likely a BSI issue

[rd070707]

okay so i got planet today. doing a global test, no faults found in the bsi, engine ecu had recorded 2 egr faults 2 turbo faults and one about air flow etc etc.

i cleared the codes but the only one that remained was : permanent fault. diesel pressure signal

i need to charge the battery fully so i can crank the engine and get live data

[rd070707]

okay so looked at live parameters on planet when cranking and rpm was near 300, it has crank cam sync. but before i got to test the fuel pressure the battery died. either the battery must be duff or the starter is causing problems cause it will only turn a couple of times then die. funny thing is the battery voltage returns to 12.6v 10 seconds after dieing. i then did a global test and the engine ecu had the following faults:

P0340 CAM SENSOR SIGNAL
P0380 PRE HEAT RELAY STUCK
P0190 DIESEL PRESSURE SIGNAL

could the glow plug relay be anything to do with it?
ideas?
