Xantia won't run / Camshaft sensor replacement

skog77 · Post by **skog77** » 13 Apr 2014, 16:06

Hello there,

I parked my 2.0 8v Xantia Automatic one day, and the next day the thing just would'nt start. Starter runs, cam belt is intact, but no spark at all.

I've replaced the brown fuel pump/ecu relay but it didn't help, so now i've ordered a camshaft sensor off ebay. But i can't see where it goes as the cable dissappears behind the distributor.

As anyone changed one of those before?

Sits on top of the Bell House, right next to the block, under all the pipes and cables.. you might need to dig for it.

If that doesnt help, it might be the Ignition Amplifier on the back of the Distributer.. (If it has one)

Been busy with easter, going to try again now.

Don't think it has an ignition amplifier, it's a 2.0 8valve.

I thought the camshaft sensor was connected directly to the distributor, but i realize it was further down. I was able to find and replace it despite it not really being possible with the hands of an adult.

Still, same thing. Starter runs, but spark at all. A used distributor will cost me 100 pounds in Norway, as car parts are stupidly expensive. Going to have to think about what to do next.

Skog,

There is no cam sensor on these engines and no ignition amp. Only the TCT had one of those IIRC. The crank sensor on the bellhousing is the only timing sensor and generally is very reliable.

Does yours have a keypad immobiliser? If so, does the green light come on when unlocked? If you see a red and green on together the car won't start as this shows a loss of comms between the keypad and ECU.

If you can advise me of what Engine ECU the car has (I think it'll be either Bosch MP5 or Magnetti Marelli) I can supply full electrical diagrams to help you resolve the problem.

Yes it was the crank sensor i replaced.

My car does not have an immobiliser, and i have the Magneti Marelli ECU, Jim

Perfect,

This diagram should help on the electrical side then...
