I intended to make a new thread but somehow i ended up responding to this one. Since im not a premie and can't delete it i am wondering if anyone can help me out. I have a s14 with a redtop swap and i am having a problem getting the fuel pump to prime. When i test the relay, it is only giving off 5 volts at prong 1+3. So is there anything that would cause the relay to be giving out voltage lower than the battery or is the relay on its way out. ECU is from a working car and battery is fine.
