Ok so when I'm in neutral my car doesnt hesitate, but when I'm in 3rd, 4th (have not got to 5th yet) gear at 4k rpm my car hesitates and when I give it more gas it stops but then it kinda feels sluggish. But the sounds healthy when I rev it in neutral. I looked everywhere i could think of so... i need some help.
 
And I'm pretty sure it's not a boost leak because I smell fuel inside and out of the car
 
Arent there two return line one being on the pump
Maybe on the pump mount but not the pump itself. Still..a leak on the return line does not affect the driveability of the car. The fuel pump could be sitting in a bucket so long as its submerged in fuel
 
And I'm pretty sure it's not a boost leak because I smell fuel inside and out of the car
Fuel smell has what to do with a boost leak? You probably do have a fuel leak but the two aren't remotely related. You wont know you have a boost leak unlless its painfully obvious or you actually test it and not guess at it
 
the way I checked for leak was two ways using smoke and using soapy water and the only leak I found was where the intercooler piping and throttle body meet and I fixed that leak. now its when I try to start my car it clicks once and doesn't start. then I'll have to turn it off set the car back in the on position then after like ten seconds it starts then when I'm driving it like around 4000 rpm plus it starts to stutter. some people say that the starting issue is definitely the coolant temp sensor which I replaced 3 days ago and nothing. the symptoms I'm getting are apparently of a failing fuel pump.

No. The symptoms you are presenting aren't indicative of anything yet. Educated guess at best. If you believe coolant temp is good what does the ecu say? If you don't have a datalogger at the very least go to the local auto parts store and borrow a scanner. The starter click thing could be battery. Ground. Ignition switch. Connection at the starter. Or starter relay. Start by at least cleaning and tightening connections. On the smoke and soapy water did you actually pressurize the intake? If you didn't that is not a proper boost leak test

Clicking has nothing to do with fuel pump. It won't start because your starter isn't even turning. At least that's how I read it. When you are getting stuttering is this at wide open throttle or just cruising at highway speeds?

  • No....too vague
  • Rising Temperature. ...well is it?
  • Fuel Pressure Gauge. ...what does it say? Do you have one?
  • Loss of Power When the Vehicle Is Under Stress. ...
  • Surging. ...
  • Decreased Gas Mileage. ...
  • Engine Will Not Start.not crank or not turn over? Still very vague and not necessarily true.

Both and I know about the starter issues it's the sputtering I'm worried about
