How to check fuel pump voltage
As I mentioned in another thread, fuel pressure is low. If the pump wasn't getting enough juice, it would certainly affect pressure.
I have a Racetronix 255 pump and the hotwire kit. Do I simply unplug and check for 12.75 volts? Wouldn't draw increase under load? How do I test that?
