Suggestion

The DME/ECU will definitely throw codes for problems to look for if the entire left bank is not working correctly, and the car will run like crap, not idle and will probably not run.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

My friend has a 2000 996, bought as a non running project. He replaced the coil packs today, the car fired up idles fine but the left bank is cold. No fuel in the exhaust. Any ideas?

POST 2Original post

Quotes source post: 14827380

"idles fine" and "left bank cold" kinda contradict themselves. Start with basics, every cylinder needs three things to run, compression, fuel, ignition. Test compression, then test for fuel, then test for ignition/timing. Report back for more detailed help.

POST 3Original post

What does that mean - left bank cold? If it starts, runs, idles fine, and is not throwing misfire codes, then I don't understand what the problem is. The DME/ECU will definitely throw codes for problems to look for if the entire left bank is not working correctly, and the car will run like crap, not idle and will probably not run. You need to provide more precise information on "left bank cold".

POST 4 / ORIGINAL POSTEROriginal post

Getting back to all who replied, thanks for the feedback. The car does idle fine, and has cold exhaust. No valvetrain noise. Pulled plugs no spark, no fuel. Told him to get codes. Most likely DME.

POST 5Original post

It can�t �run� and be cold... I also doubt that the engine would run on only 3 cylinders... I smell a troll...🙄

POST 6 / ORIGINAL POSTEROriginal post

The car absolutely can run on one bank, The crank is still turning and moving pistons and valve train. If you don't have any constructive advice don't assume everyone is trolling. I have way better things to do than waste everyones time on forums.

This is a source reference. Confirm exact model applicability in the original material.
