Anyone had problems with the fuel pump fuse blow while barely boosting? I was just driving around a little bit ago, barely got on the gas, maybe 2-3psi and I hear like a clunk/pop sound. My vdc had kicked in and right when it kicked in is when I heard the sound and then the engine died. I pulled off to the side of the road and tried restarting but all it would do was turn over and not fire. Checked my fuel pump and it wasn't kicking on when I turn the key on like normal and fuel pressure wasn't going up when cranking. It blew the fuse under the passenger side cover that you have take off, it was the top right one that that says ign contr and eccs but also runs the fuel pump. Any ideas why this would just blow. It is a walboro 255 with return fuel system on a greddy tt.

 

Was everything OK after replacing the fuse? If it keeps happening it could be your pump is failing.

 

well I've only driven home which is like 5 minutes. Everything sounds fine but I don't want this to keep happening.

 

you most likely have a wiring issues or electronics issue that blew the fuse that allows your ECU to power on. Without the ECU, your fuel pump will not prime or activate.

 

hmm great, guess I need to go through and look through everything that the previous owner installed, It just has emanage blue and j&s safeguard right now, going to switch it out for utec when I have money, running low boost for now.

 

check if you have a short that is making contact with the body of your car. (wire on metal)

 

+1 it happened to me on the dyno when my car finished... hehehehe this bad well i wanted a back fire so badly on the dyno so i went in redline on 4th as i was pulling and lift my foot off and back fired and the car went dead.. checked the fuses it was the fule pump.

 

did you find out what caused it for you? I haven't had a chance to go through everything yet but it ran great the rest of the day.
