I got my car back from the tuners a couple weeks ago and when i got it back the fuel pump relay was ticking really loud and gets very hot. Just wondering why this is happening and is the pump on its way out. It might have hurt it reving up on the dyno. What kw are the standed fuel pumps rated for? Any help would be good.
Not entirely sure what you mean by the fuel pump relay 'ticking' really loud........however:
It's possible your fuel pump relay may have damaged/corroded relay external connection tabs (where it plugs into the relay holder). I have had similar issues with relays in other Commodores.
Try cleaning the relay terminals, ensuring that that make good contact with the relay holder terminals. I would suggest that if the fuel pump was drawing excess current (causing the relay to get hot), then the fuse would eventually melt.
Failing that, is it possible that your fuel pump was run with a very low fuel level? The pumps rely on a volume of fuel, both to provide lubrication of the bearings, and to keep the motor windings cool.
