Weird car problem; turns over, but doesn't fire;

[Woo206]

I have a problem with my 2000 206 turbo 2 liters HDI(diesel). It was working fine until I did an oil change.

I used a lifter to raise the car on its frame. Finished the oil change and it won't start again. No issues with the oil, just a different brand. Fuel is at half tank. Battery is good. Tried jump starting the car, but that didn't help. On top of that, my automatic locks stop working. Normally, when I lock/unlock, it locks/unlocks all the other doors, but that stop working too. Fuses are good. The car turns over, but doesn't fire. Tried using the cold start technique and that didn't work either.

A. What are some things I can try or take a look at?
B. What would cause the automatic locks to stop working? Electrical?
C. Thinking the electrical issue causing the doors to stop working is causing the engines not to fire.

So far, after reading some other responses, I need to check the following:
1. Fuel cut off switch. I might have somehow turned it off. I'm told its located on the passenger side, behind the suspension struts with a red cap. Can someone confirm this?
2. Reset the fuel pump. Located in the trunk? http://wiki.answers.com/Q/How_do_you_re ... h_manually
3. Inertia switch?!@#@ No clue what this is.
4. Check wire between the fuse box and ECU.
5. Check the immobilizer?!@#@! No clue.
6. Replace air filter.
Am I on track to solving my problem? Any help is appreciated!

Welcome to the forum.

Sounds to me as if you have dislodged something while changing the oil. Did you disconnect the battery? Did you remove oil filter from underneath, or from the top down the front of the engine? What do you mean by lifter?

"Cold start technique"??? Wassat??

To answer your questions.

A/ Check the plugs and connectors in the area where you were working. Near the oil filler is a plug for the cam position sensor- check that.

B/ This may not be related to engine non start. I would get it running first, then worry about locks. If they are related then you will find locks work when engine sorted.
Have you checked the fuses in both fuseboxes?

C/ See answer to "B"

1/ It's an inertia switch. Unlikely to have tripped it just changing oil. But it is by the N/S strut top and has a red rubber boot over it. (push to reset)

2/ Err...No. Hasn't got one (see above for inertia switch)

3/ See 1/ above

4/ You could, but what have you done to cause it to go faulty?? Last resort really

5/ Could be, but that's a bit trickier. Eliminate everything else first unless you disconnected battery?

6/ That's not going to achieve anything.


As already said, I bet you have disturbed something while carrying out oil change. If you have access to a good code reader, it should tell you where the problem lies.

@ Capncol

First, really appreciate the response. It'll give me better direction when troubleshooting.

I poured the oil myself and there was nothing that might have lodged it. I'll recheck the inside with a flashlight.
The battery is connected and I even tried using an external battery jumper to see if that will help and it didn't.
I moved the oil filter from the top. The filter is placed in the most awkward spot.
What I mean by the "lifter" is the equipment that raises the car by its frame.

"Cold start" for a diesel is when you turn the key, but not start it. You do that 2-3times to I think let the glowplugs warm up to ensure your engine starts. It was a recommendation I read somewhere else for diesel engines in cold temperature. It was 10C where I was.

B. The fuses are good and all connected.

I'll keep you updated once I check with the code reader. I heard Peugeots have lots of wiring issues. Thanks.

I mean externally, not inside engine.
(BTW the cam pos sensor is about 11 o'clock from the oil filler cap when viewed from above. Easy to disturb if you remove cap with cloth)

The battery is connected

But did you disconnect it?

I moved the oil filter from the top. The filter is placed in the most awkward spot.

Check down the front of the engine. There are a few electrical connectors in that area also fuel pipes run just above the filter.
Where it is tight down there it is easy to dislodge a pipe or connector without realising.

That applies to much older diesels with a fixed time glowplug relay (typically 40secs)
I have my doubts as to if it actually works because a glowplug *glows* within about 3-4seconds, the rest of the glow cycle time is to sustain combustion for the 1st few seconds until cylinder temp comes up. Obviously if it doesn't start in the first few cranks, you try again and the cycle repeats

Those HDI's have a glowplug timer controlled by a temp sensor via the ECU. If it is very cold, glowplugs come on for longer. You've been given duff info I'm afraid.

1. The cam pos sensor is on there tight. Everything else is on there tight.

2. Did not disconnect the battery during the oil change. I did remove the battery today for 10mins and put it back on. That didn't do anything.

3. Checked in front of the oil filter, no issues.

I had someone else take a look and they didn't see anything wrong. I did notice today, when I started the car, the RPM gauge went up past 1.5, but still didn't start.

I called a garage and one guy told me that the key I'm missing, the primary, not the backup has a chip inside that needs to tell the car to start. Don't know if this is true, but I only have the backup key for now. Could that cause the car not to start?

I think my only option now is to take it to a Peugeot dealer and have them figure it out. Any other thoughts?

Were you using that key OK prior to the oil change? All keys should be coded, it's just that the main key also has the remote buttons.

What he is saying is that the transducer is missing from the key.
(it is a chip that *talks*to the ECU, if the transducer code matches the ecu, it will switch off the imobiliser & start) You would have an indication of imobiliser prob on dash.


Try a good independent garage before you pay main dealer prices.
