P0463 while out of state

EdGs · Jan 1, 2023

Went to see the Grandkids in NC, and left there for the trip home to SWFL early this morning.

About an hour in, I popped a check engine light. No change in behavior from my truck. Ran smooth, EVIC showed normal oil psi, oil temp, coolant temp, etc. Oil and coolant levels good.

Pulled off the interstate and luckily there was an Autozone right there. Engine code P0463

I actually bought a scan tool and reset the code. Took a chance and decided to continue on. Engine light recurred and this time, got a Low fuel with fuel gauge dropping to zero as well. Intermittent, gauge cut out a few more times over the 800 mile journey.

158K on my 2015 Ram 1500, so I might just be due.

Am going to call about OE pump and sender tomorrow. One thing that did happen was while I was away, I had to jump the edge of a curb to avoid a collision. Did not bottom out or anything like that, slow speed. Driver side, though.

I will be checking for the obvious as well, connectors and wiring issues, just in case.

Any suggestions on specific tests I can do or things to check for? I am hoping the level sensor is separate from the pump, but prepared for the fact it might not be, also prepared to buy an OE replacement if need be. Might be better to do both at once, too.

Any guidance is appreciated, TIA

Definately planned on that, Rick.

Well, looks like one assembly.

Got a ways to go before my tank is near empty.

Just FYI Mopar fuel pump assy # 68092755AA

Dealer price $545 plus $50 core + tax

Lubricating gel not included, lol

P.S., dealer says o-ring separate # 55366298AA

$47.58

However, Mopar sites online show o-ring with pump in exploded diagram.

Mopar website lists pump for $360ish + $50 core. Still ouch, but a little less.

It is very possible that connecter could be the culprit especially that you said doing that curb jump. Drivers side under rear of the fuel tank there is a wire harness for that sensor. Try and reseat maybe disconnect and reconnect. Maybe just maybe. Might save you a few hundred and a pain of dropping that fuel tank.

Ive had to change out a few fuel pumps in my life and darn near every time that freaking fuel tank is nearly full lol. Also good you are going OE I have learned my lesson the hard way and have had to re-do the job a couple months later on a GMC.

I will be checking the harness. There is no noticeable driveability, and in fact, my check engine light went out today. Not getting my hopes up though. Am going to run it as low on gas as I can before I screw around with it.

With 158k miles, it has had alot of use, maybe I'm due.

Biggest worry is not knowing if places online have stock, do not want a backorder. I am considering aftermarket, delphi would be my choice. Still undecided, been through other aftermarket parts issues as well.

Not looking forward to the job either way.

Do you happen to know if that’s a supply chain inflated price ? I know mopar parts always more expensive, but that’s almost 3 times as expensive as aftermarket pricing.

EdGs · Jan 3, 2023

@huntergreen, online Mopar sites are $360 ish plus core.

@GTyankee, been on RockAuto site, have ordered from them many times, but am leaning towards the OE pump.

I did order from them what I believe is the OE fuel level sending unit only, took a chance for $16, shipped.

Still have to drop the tank and pull the pump to change, and still debating the OE/aftermarket choice as well. Truck is running well, and my check engine lamp is off. So far, so good.

could of been worse and pump went out at 58k. Maybe borrow DILLIGAF'S lift. At minimum jack with board is your friend.

Seems the OE fuel pumps are on National back order. May have to go with aftermarket.(watch at 30:00 mark) Were you able to source one??

EDIT: I see the 2019 unit is different than your year so that is good as far as not National back order.

I just thought about that fuel pump bypass trick

I do have access to a lift.

I am seriously thinking about lifting the bed to access the pump. Also looking at the Delphi pump. I am really tight on finances at the moment, and have some other bills coming due as well.

On the bright side, my check engine lamp has gone off. Did I get lucky? (probably not..lol).

ThunderMug95 · Jan 3, 2023

Thats a tough call…If your dropping the tank to do the sender, I’d just go ahead and do the rest. Just my 2 cents. It would suck to have to repeat that…

Is really hard to say. Most likely on borrowed time but who knows for how long. Older GMC truck I had the pump stopped working temporarily the hammer trick worked getting it working again for 4 months before going out for good. You may get lucky may not.

If i change the pump and repair the sensor on the original, do you all think it would be ok to keep it for a spare?

Not sure if it would deteriorate over time after not being submerged in fuel. Thinking out loud....lol

Im not sure even if its “good” I’d keep a 7+ yr old spare. Its not like a bald tire to get you home…anything rubber soaked in gas that long then sitting on a shelf…Dropping the tank on anything is a pain in the ol’ **** roast!
If Im dropping my tank, Im replacing any wear item I can.
Fir instance, I’m installing a TruTrac sometime in the near future, Im replacing seals and anything else I can on the rear axle…brakes and rotors excluded (Theyre less than a month old).

It censored “r-u-m-p”?!?! Is that some derogatory term outside the US I am unaware of

On my GMC 2500HD truck the sending unit went out. Common problem with the sender metals "sulfating". Chevron gas treatment every 5000 miles or so is supposed to keep it clean. Will be doing that in the future. Yours is a different problem with the pump though. The point being, when I replaced mine, the GM OEM pump was made by Bosch. The replacement that I used was Delphi. I went with the Delphi because alot of my older GM's used Delphi parts as OEM and they are an OEM supplier. I felt confident with Delphi and they had, I believe, a lifetime warranty. When I compared the old and the new pumps, it was quite obvious that the Delphi was more substantial. I believe there was a tag on the unit indicating that one of the benefits of this unit was the gold-plated contacts or something like that. At least it looked like they identified one of the problems of the original design.

To Me
The advantage to lifting the bed is that you get to actually see everything that you are doing.
There is no chance of pinching a hose or wire as you are reassembling everything.

To illustrate, this is my Ram eco-diesel as seen from above
