Installed new harness tonight, confirmed 12v at plug when cycling key, pump still not powering on.
Im scratching my head now. Could it really be the physical bulkhead connector? Pins look fine.

Which plug is showing 12V? The one on the hat or the one actually plugged into the pump?
Could be your pump is dead.

The reason I attached the harness, I initially was just checking the bulkhead plug and when I pulled the plug out and put it back in, I cycled the key and the pump came on. Figured end of story, it's the connector...
I cannot even get the pump to come on at all regardless of what i do at the bulk head - hell I just put a pin connector on it with a lead and hooked it to 12v, still nothing.
In progress of pulling the hanger out now. Guess my question would be - it's referenced above about the stock bulkhead connector not being able to handle the higher current - is there an aftermarket replacement for the stock one - or are we talking about drilling into the bulkhead or tank and putting a new bulkhead wire harness in?
Thanks for the help,
John

Racetronix sells a replacment for the stock bulkhead that has a higher current capacity. I actually bought one to use on my DIY dual pump hanger recently.

New connector installed, pump is back to running.
I tested the old connector and I’m getting 12v on both sides, but appears there is some corrosion on the pins, so hopefully just a matter of pins not having good contact. Fingers crossed.

Old thread but wanted to provide an update.
Even with the new connector I still saw random problems. I ended up converting the grounding terminal on the bulkhead to a power line to split the load and it’s been running great since.
Grounded the pump to the bulkhead itself and grounded the Bulkhead to the frame.

I did run a second positive lead as suggested and I just got my 1 year reminder on amazon photo
. Been working great, no issues! Really happy with this setup! Simple and effective.

I have a 99 and the bulk head is grounded already. Are you saying ground the bulk head to the frame????

The bulkhead electrical connector into the pump has 4 pins, one is a positive for the pump, one is a ground. The other two are for the level sensor. Take the ground wire from the pump inside the tank and ground it to the strip that's bent off the bulkhead plate itself. Then take the positive wire and splice another to it and run it them both the positive bulkhead connector and the original ground pins. Then combine them both on the outside back into one wire and to the relay harness.. And take a ground wire and attach it to one of the pump mount plate bolts to the frame rail.
