2001Tiptronic turns over, runs and then dies
 

Any ideas/help welcomed.
I work away and during lockdown my car stood undriven at home started ocassionally but not driven.. when I got home recently and tried to start it all was not good.
Battery is fully charged.
Turns over, fires and runs for a few seconds and then dies.

RPM movement.

Sometimes if accelerator pressed it runs for a few seconds longer and then dies😩😩

The CPS is new so ( hopefully) should not be the problem ?

Any ideas ?

That screams fuel issue. Filter? Bad gas?

Check to see if you can hear the fuel pump prime up when you turn the key, before you start it
It will be a one second buzzing sound coming from the right side by glove box.

Will do .

Thanks

I'd been wondering for years what was that noise.

I love this place. :cheers:

I'm betting fuel issue too but I did have a 996 with a bad dme that had those exact symptoms.

UPDATE
Thanks to everyone on here for their invaluable help in fault finding and enabling me to finally get my porker running again.
I replaced the crank position sensor - car still had same symptoms - turns over but doesn’t fire , and when it does it dies immediately .
I put some more ( fresh ) fuel in just in case it was actually empty.- same old same old.
Got a can of MAF sensor cleaner😎 but thought I’d try the “test” I had seen on posts on this and other forums about MAF sensors i.e remove it and the car should start and run ( possibly enabling you to limp home or to a garage) - if it does start and run then possibly your MAF sensor is the problem.
Removed the MAF sensor to clean it but tried to start with the sensor removed and 😁😁😁😁😁😁yeeeeeeees. She started and runs.
Cleaned the MAF and let it dry.
Re-installed and ………no change - back to turn over fires and dies.😩😩😩
Thought to myself “ oh well at least I know to replace the MAF Sensor .- removed it again - retried without MAF sensor. yep still starts and runs - no fluke there. Decided to put the MAF sensor back the car until new one arrives - always the optimist- gave it a few more sprays with the cleaner - allowed to dry - inserted key - turned over , fired and ran like it used to .😁😁😁😁😁problem solved 👍👍👍
Of course it may be that the crank position sensor was not faulty all along But as I am not eager to repeat the polava of refitting the old one to find out , apart from a possible bench test I will assume I have a spare now.😎😎😎
Thanks to everyone for their help .
Gosh bless the internet and this forum .
