starting issues
 

I inherited this Saab 9-3 from my dad and they had issues a year ago with it starting and changed the NSS, it started having an issue lately of not wanting to restart then after about 30 minutes starting, so I replaced the CPS and DIC. It makes a squeaking sound like a pulley and acts like it has a hard time turning over and when it starts it wont idle and dies when you take your foot off the pedal. Any ideas? Could a tensioner or idler pulley cause the "bogging" issue and maybe cause it not to stay running? Someone suggested I have the timing checked also.

I recently had the the fuel pressure checked and will have the compression checked also in next day or two.

Never mind, I found out that the oil pump had quit was reason for no start and sound was chain. I now am the proud owner of a paper weight. I don't understand why it never showed a code for the oil, I had 3-4 diagnostic scans ran on it.
