Fuel pump

This gets my vote. My car did the same thing when the fuel pump went bad.

Tapping fuel pressure,

1st inspect the rail for a test port (I am not sure we have one) idk!

2nd have the correct fitting to fit in between the rail / pressure line.

3rd, quick cheap and dirty, buy a $10 plastic fuel pressure gauge and cut the fuel line.

It is Sapphire Black and has the beige accents in the black leather interior. The only thing it doesn't have is the Rear Seat Entertainment. I have been quite impressed with it as it handles really well and is faster than any CUV should be. If you like Swede cars you would like my 1971 Volvo 144S with 16K original miles and completely original.

I'm going to try my regulator and fuel filter first
if nogo I'll tap into the brass peace on the fuel rail
I'm assuming we need a adapter for a gauge on that one

replace my fuel pressure regulator and filter and she didn't wana feel like it would so we went to get the pump and lo-and behold it started to feel right half way out to the store lol gues it was just air pockets but it runs and has a compleat tune up :D

Update it seems to of just had a sliver of life left in the pump so I got a new one but now my s.c kicks off at wot so I'm going to replace the pump and see if it still dose it

issue has been completely resolved now with a maf from amazon
