Hard starting and rpm fluctuations. Replaced battery, no change, replaced fuel filter, no change. Assuming it is the fuel pump after reading all the posts.

Car starts but soon stalls out. Took it in to the Porsche dealership. Said it was a the fuel pump. I have owned many cars in my life and never had a fuel pump issue. Would think a Porsche would have a better pump. $1300 in repair cost. Amazing
No starting after several seconds, getting worst every day. Car under warranty, they told me several problems with gas pumps and Porsche replacing the pumps but ohh surprise no pumps available...!! Already a month waiting for the replacement. Porsche service: same quality Lada Niva gives to their customers in Polond...
