'99 Series 1 - newish Fuel Pump no power
Hi,
I am hoping someone may be able to help as to what to look for for a 1999 Series 1 Discovery with no power to fuel pump.
The fuel pump was replaced about 5 years back as the old one died. It ran well, but within the last year or so began having issues where it would not start on the first turnover.
Just had the local AAA out and it seems there is no power going to pump
Checked:
- Fuse F6 seems good, but am buying another one today
- battery is good (AAA tested and said it's good to go!)
- tried the fuel pump inertia switch beside washer reservoir but no difference
- Fuel filter replacing tomorrow (may as well)
Now, the symptom is when I place the key in ignition and wait for the chimes to finish, it only chimes twice now. Previously it chimed 3 times.
What else can I attempt to check? I don't have a multimeter, but I was thinking relay under the glove box, or possibly looking underneath to see if any plugs have shorted that go back to the fuel pump.
As always, thank you for your time and help

If you get under the truck you'll be able to follow the short section between the pump and wiring harness. Look for brown discolored portion on connector. Also you have a fuel pump relay on the passenger side of the engine bay, small black box behind the battery. Give that connector a check, can actually remove the cover to check the coil. More than likely a bad connection which is most common fault.

Well, it appears that we found out what the culprit was...
The fuel pump was replaced about 3 years ago, not the 5 previously mentioned.
We took a look at the connector on the fuel pump, and saw this:
Connector is singed
Connector is singed, and one of the pins is stuck inside.
You can see the pin is missing in lower left corner as it is stuck inside the connector from previous pic
WFX101020 pump model
So I can source a new fuel pump unit from BP of UTAH, but where do I find a similar connector that I could splice?
Thank you for your help everyone.

My sig would provide a great source...... Paul Grant. It's a short splice connection with two connectors between the main loom and the pump. When ready to reinstall use dielectric grease on the pins/sockets and silicone over the connection so water intrusion won't take out the new kit.

Thanks
P.s.,
Will report back once the new pump is installed
