I just checked my fuel pressure it's 60 PSI and it maintains 60 PSI even when I mash the throttle the car has black **** in the tailpipe and on the bumper and it loses power once it warms up I was trying to start with the fuel pressure regulator but cannot locate it any suggestions or pictures

 

 

I have upgraded it

 

The fuel pressure reg. is integrated into the fuel filter at the rgt. rear under cover next to the differential. Use the forum search at the top. I'd be certain your "upgraded" coolant pump is actually working properly first. But it does sound like you may have a Rich fuel ratio happening. "Black ****" in the pipe is normal, but shouldn't be so bad as to soot the bumper I would think. Stock fuel pressure is typically 58 p.s.i.

 

Ok thanks I hear it come on and go off here and there my intercooler pump

 

Goes off?? Once it comes on it rarely should shut off unless your out of gear. I did an early video that showed the s/c stayed on after starting and the pump should continue running. I dont see how a LACK of cooling could increase fuel - soot. When the engine sees higher temps it would tend to lean out, rich when cold. Do you have a code reader? Sounds like the O2 sensors are not operating correctly, they are what control fuel flow. Woody
