While making a left turn and accelerating, my truck quickly looses power. Any one have any ideas?
I have 172000 miles. Original lift pump, at least no new pump since 64000 miles.

 

i have got this once when I was at a stop and made a hard right turn. I have a brand new transmission

 

fuel slosh? I can't think of anything else and that's what I came up with .

 

A lift pump performance is not likely to depend on turning. Are you sure it is not your perception? I myself tend to lean a bit when turning, and instinctively let off of the pedal when doing so.
I would install a FP gauge to see if the old LP is still alive.

same problem .just did lift pump .runs like new.
