I've got a 2004 Impala LS. Around ~130k miles on it. Very well maintained.
Appears to start successfully and then instantly die.
Has fuel pressure. Battery and alternator are good. Starter is strong. Appears to have spark when starter is engaged, but cuts spark immediately after engine successfully starts.
Have been through all four fuse boxes looking for obvious issues and cleaning contacts on anything related to ignition / starting / engine / etc.
Any ideas? Could this be a PassLock issue?
