I have no power at the pump.
I have 12.4 volts at pin #13 on the relay board. No power at pin #5 or 7, old eyes can't see the stripe colors very well. Fuses are good. Am I missing something? Thanks in advance. |

Power to the fuel pump relay is provided by the power supply relay.
With your voltmeter, measure voltage from the FI plug pin 1 to chassis ground. With the ignition switch on, this should be 12V. Also check the voltage on both sides of the 25A fuse. Touch the spades holding the fuse, not the fuse itself. This will check the connection of the fuse to the spades. Attached image(s)
