Fuel pump stopped working a couple of days ago, could it be the relay board Options

[JimN73]

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.

I'm a bit confused on what you have found so far.

Have you determined that the Power Supply Relay is on?

The power supply relay on will provide 12V at pin I of the FI connector. Do you have 12V at pin I of the FI connector?

Have you determined that the Fuel Pump Relay is on?

Checking the FP relay is a bit more tricky. You can pull the relay and place a small wire in the FP socket on pin 87. Install the relay, turn power on, and measure 12V on the test wire.

If this is ok, pull the 14 pin connector and FP relay and measure resistance from the FP relay pin 87 to pin 13 of the 14 pin connector. Should have zero ohms.

As an aside, I've found when working in the engine area for more than 1 hour, if you remove the engine hood you will have much better access to the items you're working on. The hood is held on with 2 10mm bolts and is easily removed and replaced.
