help with zero fuel pressure
Alright, so I'm driving to a friends house and the car just dies, so i pull over to the side of the road and try to start it and it would only stay on for about a second or 2 then shut off, then i check under the hood and everything looks ok, so then i try to start it again and it just starts cranking over but wont turn on. i then try to hear if my fuel pump comes on but i don't hear anything, i also check my fuel pressure gauge and there is no fuel pressure. could this by any chance be a bad fuse or relay, or did the fuel pump go out. BTW its a 03 z06 and i believe the fuel pump is on top of the gas tank, it also has a kenne bell boost a pump and a racetronix harness.

Check the fuses 1st... Then check the wiring harness for your racetronix. It may have gotten jarred and gotten too close to a hot pipe. I lost my Fuel pressure once when the hot wire for the fuel pump got too close to the manifold. Fuse looked great.. but no pressure..LOL

Alright everyone, i had checked all the factory fuses yesterday before i had to call a tow truck and everything looked great. today i checked a couple of other things and i found that the fuse for the racetronix harness blew out. i replaced it and the car started right up. i really don't know why that happened, but I'm thinking it might of had something to do with a bad ground i had a couple of days ago. thanks everyone for there advice.
