2002 s60 non turbo will start and run for two seconds and stall. It will only restart after cylcling the key and run for two seconds each time. It has 55 psi fuel pressure, it loses the spark and shuts off the injector pulse. It seems to be related to the immobolizer but is setting no dtcs. the cem was already changed antenna ring, ignition switch, nothing seems to be working. Anyone run into this problem before any help would be greatly appreciated.

 

Try a different set of keys. It may be the key and not the immobilizer antennae. Was the CEM replaced at the dealer? May be a software issue.

 

Yes two different keys do the same thing and both have been reprogrammed and are recognized by the cem. yes it was a new cem installed by me at the dealer.
