C4 1.4kfu doesnt start, p0341, help

Unread post by Robert1000 »

Hello. I own a c4 1.4 16v petrol, engine code KFU (ET3J4).
Car ran very well until now. Now it doesn't start. Replaced the spark plugs. Fuel pump works.
Battery new (and good), clutch replaced few months ago, timing has 10k kms on it.
The timing belt seems ok, well tensioned.
Car tries to start but doesn't. If i massage the acceleration pedal while cranking, it starts for a bit but shakes very very violently then dies.
Only one code storred : p0341. I deleted it and reappeared.
Help, please!

P0341 indicates camshaft position sensor. Have you looked at that?
Checked injectors for blockage?

I don't think this sensor has a problem. Nobody solved such a problem by replacing that sensor on these cars.
The spark plugs are wett with gasoline after i crank the engine, it seems that there is fuel supply. Engine doesnt start even on starting fluid.

What happened to it? Did the engine stop whilst driving or would it just not start one day?
Is the timing belt OK?
Are you getting a spark?

What makes you think it is not the cam shaft sensor, have you tested it ? In this topic P0341 was fixed by replacing a cam shaft sensor viewtopic.php?t=67900 These sensors do not cost much so if you are going to spend money replacing lots of parts hoping to get the right one before wasting too much money, this would be a good one to start with.

The car ran absolutely fine until now. I left it in the parking place for 3 days, then when I cranked it it wouldn't start. I gave it a long cranking and the engine started with very violent shaking and stopped.
