Peugeot 206 non start

[nathhh8]

Hi all new member here. I have a Peugeot 206 2005 plate 1.4cc, 16V. The vin number is VF32AKFUF 44293773 and has done just under 50,000 miles.

I've had the car for a little under a year now, and a few months ago I was experiencing loss of power, the engine management light coming on and fault codes relating to faulty lambda sensors. I changed lambda sensors with plug and play ones. The car got slightly better but still experienced loss of power when cold - and intermittently once warmed up. The management light came on, but not as often as before.

Then, the other day i got to the top of my estate and went to pull off and there was no revs. I assumed this was the same issues as mentioned before so put the accelerator all the way down, but there was no response. I rolled down the street and lifted my foot off the clutch to see if the clutch had gone but the car kangaroo'd. So i turned the ignition off and tried to start the car again and just got a long "humming" noise (hard to explain) which I hadn't heard before. So i luckily managed to roll the car to my house (clutch down). I got out my cheap ODBii code reader which gave me a fuel trim fault p0170 and a crankshaft sensor fault p0341. I quick bit of research told me that this fault was related to the camshaft sensor on the right of the engine block, which was related to the cam belt. I took off the top cover to find my belt had sheared, not snapped and got tangled towards the back of the cam sprocket closest to the steering wheel (can't remember which cam)

So I bought a haynes manual new timing belt kit (belt, tensioners) and a water pump. And a new drive belt and camshaft sensor for good measure. NB when disconnecting the battery i didn't follow the correct procedure (again, i didn't know about the BSI etc, my own fault again) I swapped the belt, but foolishly didn't lock the crankshaft as on guides online and even in the manual I didn't see anything that said lock the crankshaft. Obviously the car didn't start - cranked but not firing - and after further research I found the locking hole just above the oil filter. Before I found this I changed spark plugs (as i was going to service my car that weekend before all this happened and had already purchased air, oil, fuel filters, plugs etc) and checked for spark, and i could smell fuel so i assumed there was fuel as well. At this point the dash said economy mode active and after further research i found out about potentially corrpupting the BSI and potential immobiliser faults. However, the BSI seems to recognise both keys in the ignition (beeping sound when left in)

So, like mentioned after more research i then proceeded to re-fit the belt, locking both cams with 8mm and 5mm bolts, and the crank with an allen key. I checked, checked and doubled check the timing marks on the new belt and on the respective cams and crank. I cranked the engine a total of 6 times (following the steps in the haynes manual) and everything seemed fine (no loud banging noises of valves and pistons) During this time i had also swapped the camshaft sensor sensor on the right of the engine bay - as i seemed to get an overload or open circuit reading. I cleaning the MAP sensor and rechecked all other sensor connections.

My car still won't start -the cam belt rotates and everything sounds good and healthy - but there is no fire. I have revs when cranking and lights come on the dash and everything kicks up normal as it would when the ignition is turned on, just wont start, and I have checked all fuses. I still get eco mode and i have recharged the battery, reset the bsi and obviously since then been disconnecting the battery correctly.

I have done live readings on a cheap reader and get "0L" on fuel system bank 1 and the spark ignition timing before top dead centre sometimes reads 0.00% or 45ish. It seems to appear when im not paying attention and looking on forums and when i notice it resets which i assume is the ecu.

My next steps were therefore to start investigate fuel injectors and pump (although i'm sure i can hear to pump priming) and start looking at compression etc - however this is really out of my depth (as you may have already read!) and i just wanted some help or advice.

Sorry for such a long post - and hopefully ive given enough info in as little as a confusing way as possible

Thanks, Nath.

You will have bent the valves which is why it won't start. A compression test will prove it.
This engine WILL damage the valves when the belt snaps. Sorry it's not better news.

Oh no that's not what i wanted to hear. I thought because the belt was still on when the engine cut out, i may have been lucky. i'll get someone with the kit and know-how to do a compression test.

thanks for the reply. ill post back when i get it done to confirm

If the teeth have sheared off, then the cams will have gone out of time and contact will occur.

Hi everybody, i dont usually give advice on forums, and can only do basic repairs, so will not be checking in for replys etc, but ive had a lot of trouble with a crank sensor replacement lately. my car wouldnt start after an oil change and shuddered violently when turning the ignition key, throwing up the crank sensor fault. turns out there is 2 different crank sensor replacement options!!!! i bought a cheaper one to save a few quid, and found out there are different strength magnets(also slightly longer), i fitted 2 sensors i got from eurocarparts, thinking maybe the 1st one was faulty. after getting the same fault reading i went to a local mechanic, they ordered 1 for me which had twice the magnetic capability and it started right up.
i like everybody else here probably spent countless hours researching this fault but this 1 worked for me. id ask a local, non-dealership, mechanic to advise you about the sensor differences. they look exactly the same bar the magnetic capability.

well, good luck cause this had me stumped! i dont know why it happened after an oil change, im assuming it was just a coincidence.
