ninoG60 0 Posted January 7, 2019 Hi everyone, I have a non buzzing underbody fuel pump on my 1.8 16v corrado, it used to buzz when turning the key, would I be correct in saying that its probably dead, if the one in the fuel tank is getting power, I'm assu ing that the relay controls both pumps so it would mean that the relay is working ok? Thankyou Quote Share this post Link to post Share on other sites
fendervg 33 Posted January 7, 2019 The relay would provide power to both. Easiest way to check if the pump is working is to put 12V from a spare/hobby battery to the terminals and see if it runs, but it does sound like it is dead. Quote Share this post Link to post Share on other sites
