Hi.

If you are sure that problem is fuel cutting off (no fuel to injectors), then the problem is related to the fuel pump.

Check first fuel pump relay and fuse (if present). A better test can be done reading volts at fuel pup while problem happens.

If the fuel pump is powered and electrically fine, then check fuel pressure, to understand if fuel lines and pump are definitively OK.

Here a gauge to test the fuel pressure: Lisle 20300.

If you need more help, please give me full info on the vehicle make and model, and possibly more info on how the problem occurrs.

Regards.

Ginko.

I think you are on the right track. It sounds like you have a fuel flow problem and those are the two items that immediately come to mind. I would start with the filter and then move on to the fuel pump if there is no change.

Polo 1.4 cutting out every 30 seconds


Do you hear the fuel pump cut off? Once your pump reaches pressure it should cut off. Also you can try and remove your fuel cap and see if the car will run just know it could cause your check engine light to come on so do not run it very long. If it continues to run with fuel cap off I would say it is your fuel pump. Good luck with that and the best thing to do is get a fuel pressure gadge and see what kind of fuel pressure you are running. I know there are some parts houses that will loan or rent you tools. Good luck.
