hello guys for a few months now I have been having a issue where I will drive my car say to go run errands leave it sit out in the parking lot for 30 min to an hour it will not start back up. it will just keep cranking over. I hear the fuel pump prime when I open the door. I check all connections all are good try again still will just keep cranking. I have no engine codes when read with vag com. I have tried starting with the maf sensor disconnected still a no go. I end up just waiting for like 20 more min then the car starts up fine I am not sure what the issue is please help if any others have had the same problems.

not sure but i would replace the fuel filter and see if that helps. It's cheap and easy. Good to do anyways if that's not the issue.

Only have 22 k miles on it so far I could do that but that doesn't make sense about having to wait to get it to start up ?

*lilfleck* · 10-13-2014, 03:51 PM

I suspect its fuel related. It's either fuel, spark, or air. HPFP or LPFP is my suspicion.

12Mk6Gti · 10-13-2014, 03:54 PM

I have replaced the coils to r8 coils and have replaced the plugs. I use shell Vpower has only in my car

Did you check your battery?

*lilfleck* · 10-13-2014, 03:57 PM

After cranking for a while, do you smell fuel? If not, I suspect you're not getting any. You should smell fuel.

I distinctly remember smelling fuel after my K04 install and disconnecting the coil packs in order to run oil through the system.

You know I am not sure I don't believe that I smell fuel after cranking for a while

12Mk6Gti · 10-13-2014, 04:21 PM

I have not checked the battery since I have been having this issue

12Mk6Gti · 10-13-2014, 05:40 PM

Checked the battery alone with car not on 12.61 volts when charging at idle 14.2 volts

12Mk6Gti · 10-14-2014, 05:29 PM

Does anybody have the same problem as me ?

mr.zeros · 10-14-2014, 06:03 PM

Is this what you're seeing? In my case, the engine turns over but misfires badly and might stall.

The video above is a known issue. VW diagnosed it as a underperforming LPFP (though I have no other driveability problems). haven't gotten around to replacing it yet (have my doubts). Happens when the temperature reading on the water temp gauge is somewhere between 8 and 11 o'clock.

From your description it sounds like you may have a different problem, though.

These VW engines have problems starting for some reason.

The way mine does it is it will just keep cranking the tach will not rise like it's not getting a spark I did think it was a temp issue thought it was over hearing because I have to let it sit but the other day my engine was warm to touch and it didn't start so let me to believe it wasn't a temp problem

I had same problems and took car in dealer. Dealer replaced all HPFP and lines, but still happens this problems. I think this relates to LPFP...
