I have a 2015 Jetta TDI. I've had all sortd of issues with it lately, but the most recent has me stumped and I'm hoping for some advice.
I just recently replaced the HPFP about, 1000 miles ago. No metal noticed in pump or filter. Last week I noticed that I was getting slightly lower fuel mileage on the way home. Made it all the way home, including driving up my steep driveway without any issue. It would not crank up the next morning.
I cracked open the fuel lines on the injectors and I was getting fuel. Realized later that I was only getting a spurt of fuel from the in tank pump. Replaced it and now I'm getting fuel into the HPFP but nothing is coming out of the HPFP. I took the metering valve off and it's clean as a whistle.
I swapped the metering valve out from my old pump and while a little quieter, it didn't help any. Still no fuel at the injector line.
I disconnected the incoming line into the filter, and turn the ignition on and it would just spurt fuel. With both the new and old pump. Could the new pump be bad as well?
