Hi mates,
My car getting no fuel, no spark and no injector operation, is it broken timing built which results in all these symptoms ?
in other words, if the timing belt broke, will cause:
1- no fuel pumping.
2- no spark firing.
3- no injectors operational.
4- All of these.
please give your opinions from your experience.
thanks in advance

I'd say Number 4

Fuel pump driven by timing belt so no fuel
Camshaft(s) driven by timing belt so no cam/crank synch so no spark
No synch so ecu doesn't know when to inject fuel or energise the plugs so no injectors working and again no spark.

It may not be the timing belt though, Immobiliser failing to unlock the ecu would give no spark and injectors not working though you would still get fuel. Easiest way to find out if it is the belt would be to undo one or two bolts on the timing belt cover, pull the cover back and have a look.

thanks s lot for reply, my car is 406 2.0 16V RFV engine, does these engine have cam shaft sensor? or only crank sensor ??
to my knowledge, there is only crank sensor on the flywheel, in this case the flywheel spins by the starter motor and the sensor should sense this rotation although the cam shafts are not rotating. could you please explain the principle of this mechanism ?

RFR RFV type engines DO have a cam sensor BUT they will fire without it !!

Storeman is referring to a diesel engine though petrols are different I recon its immobiliser

dear reliable,
Mr. Storeman has mentioned plugs expressly, so he is obviously talking about petrol engines, I've been driving this car since 12 years and never heard of a camshaft sensor, there is only crankshaft sensor, and a speed sensor on the gearbox.
please concentrate and help me out, today I will check the timing built and let you know, Actually I used to replace yearly but this time I forgot and It's been almost 2 years of hard service.

Store man mentions a fuel pump driven by the belt this applies to DIESEL only broken belt on petrol you can tell by cranking over it will spin MUCH faster as no compression spark is fed by ecu reading crank sensor so would still spark.

As in the Derv :) do the petrol models give you the key in ignition warning with the door open just thinking of the question you asked the other day

It's a long long time since I had a petrol engined car - in fact the last petrol engine car I owned had the fuel pump operated by the camshaft. My exposure to Peugeots is with diesel engines and didn't consider the fuel pump would be differently driven but generally when a member does offer incorrect advice, someone as experienced as reliable will correct it. I apologise for the misleading comment regarding the fuel pump on a petrol engine but in my defence, I did also point out that the immobiliser could possibly be a suspect as have others including reliable and that a visual check of the belt was the best way to be certain.

Dear Mr. Storeman, Mr. Reliable,
thanks for the comment and explanation, well I've checked the timing belt yesterday it still in place and camshafts are moving along with starter motor, before I surrender to immobilizer possibility, I want to make sure whether this vehicle has a camshaft sensor ? and where could this sensor(s) located as it has 2 camshafts (XU10J4R) ?
I tried hardly to find a wiring diagram for the existing ECU (Bosch motronic MP5.2) but invain, the most similar I found is for (MP5.1.1) which i am not sure it has the same diagram, I have a PP-2000 diagnostic tool but it is not catching this ECU namely ECU not responding and this is common problem with this model as I can understand from other members threads.
could anybody offer me a useful advice ?

You need to recode the keys then as its not reading them BUT it should still read the ecu even if keycodes lost so again I recon you have a wiring fault somewhere

Cam sensor is on rear cam but its not important until you get planet reading ecu as once you get this the car will probably start anyway.

Dear Mr. Reliable,
for you information, planet is not reading ECU even before the fault happens,
I tried it before when the car is running fine.
could it be a software version problem, I am using peugeot planet 2000 09B(22.12), and if so how to upgrade or downgrade the version?
it is working fine with my second car 607, but useless with this 406.

If your Lexia has never connected to this car have you someone else Local to you that has one ? Another forum member was having issues with his connection and drove here & we tried mine

If nobody elses will connect and you have the correct revision & software that it should maybe the fault is in the OBD connection rather than in the lexia or the software

I did have all the flashing programme Etc and all the Programmes but last night the raid drive that held it all lost a drive and now I will have to get it all again so cannot help with anything software related at the moment

by the way, my car has no key pad although there was a yellow sticker inside the key fob with 4 digits code written on it. I removed this sticker when I brazed new micro switch of the remote control and kept it for a long time but unfortunately I lost it finally.
