Just had a Racetronix fuel pump installed 2 weeks ago. Was driving home tonight and it suddenly lost power and died while on the highway. Guages all went down and the "check guages" light came on. Tried to start it again and it turns over fine but wont start. Let it sit for a bit and it will start and die immediately. I took the cap off the fuel rail and pushed in the schrader valve and no fuel came out at all, even with my fiance cranking. Fuel pump again or what? Was told it could be a sensor...

 

You need to post this on the correct forum. You could put it on "Fuel and Ignition", or on "LS1 Based Engine Tech"..... but its not "Advanced Tech".
