Review on Painless Performance 50102 Fuel Pump Relay Kit: Hassle-Free Fueling Efficiency by Kevin Young

I've had good experiences with Painless products in the past so it could have been an accident. I finished the installation, turned on the relay, the fuel pump worked as expected. After completing the installation of EFI, I found that the ECU does not start the pump. I spent three hours fixing my wiring only to find out that the Painless relay had failed. I installed a new relay (different brand) and the problem was solved.
