2004 Stilo 2.6 20v - Help Pls

[whiskey mike]

I have a 2004 Fiat Stilo Abarth 2.4 20v which has been standing for a while as the auxiliary belt came off and got stuck on the crank pulley between the cam belt. I have replaced both belts, the engine turns over but does not start. I think it might be a timing problem. Can anyone help pls.

If you didn't use the proper timing tools a procedure when replacing the cam belt then it will be a timing issue.

I had the exact same problem on my 20V Coupe where the aux belt stripped and got ingested into between the crank pulley and cam belt.

When this happens the cam belt rides over the aux debris and misses the crank drive slots and thus the timing slips. The slippage is then detected by the cam shaft phase sensor, the EML will activate and the ECU will stop the engine.

Depending on engine rpm, degree of slip etc. then with luck no valve to piston interference took place.

You may have to have the EML / ECU fault cleared before the car will start.

If you have timed the engine correctly then not firing could be due to bent valves and lack of compression.

Thanks for the quick reply. I will have to find a respectable garage to try to clear the fault. I am just hoping that this is the problem
