FRPS or Fuel pump taking a crap?

[force feed]

Ok so the other day I was driving and went into boost to avoid getting hit. I was low on gas, don't remember hitting the rev limiter or not. I come to a red light and let when the light turns green I put it into gear and the car dies. I try n crank it and it starts and dies again. The next day I change the fuel filter and it was pretty dirty. I checked all the plugs and oil. Everything checked out. I turn it on and it fires right up. Today I drove it for about 20 min and it did the same shit. I let it sit for 20 min and it fired up again. I hooked up a after market fuel pressure gauge and at idle it stays at 29-30 and when I unplugged the line on the FRPS is jumped to 39-40. I haven't checked it under load yet

Any codes thrown? It is possible that the frps is going bad.

No codes have been thrown. Car runs fine before it cuts out

Try replacing the FRPS first since its easy swap

Had that happen to a neighbors V6. It would die at random times. Eventually it left her stranded at an intersection. I replaced the pump and it's still going as far as I know. But it threw a code for secondary fuel circuit.

I'll probably try that.

FRPS, pumps, or boost bypass is stuck open or closed. I just read another member having similar issues cutting out bucking while driving and it was the boost bypass. Now don't ask me how to fix it or where it is, i'm just a banker with pocket$ and a lead foot. good luck!

Lol it was actually the FRPS

Change your oil if you had to replace the FRPS. You're oil is likely contaminated with fuel now.

Already did along with the plugs

This has be thinking. Now I know the frps can go bad in two ways, right? Electrically and mechanically, no? When mine went bad I didn't have any gas smell in the oil, but for safety I still changed the oil.

My oil had a very very faint smell to it. I've changed the plugs, oil filter, oil, fuel filter and the FRPS. I data logged yesterday and everything seems to be running normal. Put about 70 miles on it so far with no problems.
