Re: Blown Fuel Pump Fuse (civster)

Blown fuses are not to be dismissed, specially in sensitive areas like fuel pumps. May be the pump has a developing short?

 

Re: Blown Fuel Pump Fuse (civster)

Civister, I would agree, the fuse should not be blowing, you need to bring it in, could be a number of things, including a faulty pump.

Fuses are not valves, they do not shut off at there rating, they are thermal devices, and cut off based on heat generated melts the link in the fuse.

For example (note at 72 degrees F, at higher temps, the time is shorter, at lower temps, longer):

15A fuse will run all day at 110% of rating (in this case at 16.5A, it may not blow per industry standards)

At 135%, blow within 60 minutes (20.25A)

At 200% blow within 2 minutes (30A)

Again, those are maximum industry standards for a standard blow (not slow blow fuse, which are even longer times).

Have you noticed it blows if running for an extended time?

I would bring it in ASAP, especially the fuel pump!

 

One thing I noticed in both occasions was that the engine started up for a second or so and then died. Subsequent attempts to start the vehicle thereafter resulted in a failure. It seems like the fuse blew while starting the vehicle.

My wife is suggesting the we should talk to the dealer and have them "step up to the plate" and either provide us with a new vehicle or give us our money back. Her concerns are what if the vehicle dies on her in the middle of nowhere in bad weather with the kids or worst, while driving in a busy freeway. She's not very comfortable popping a vehicle's hood open let alone replacing a fuse.

 

Re: (civster)

I understand your concerns, but it could be as simple as a new fuel pump, or a new wire harness, there are defective rates with everything (not that you want to hear that) but some times a part is bad.

But you need to do whatever you feel most comforatable with.

In any case, get it back to the dealer asap so they can start seeing what is wrong, and hopefully you still have the bad fuse you replaced as proof.

Civster,

Any updated on what happened with the dealer, did they figure out what was wrong??

The vehicle is finally at the dealer; I was on vacation for a couple weeks and I didn't want to leave my XC90 at the dealer for that long.

I should hear from my dealer within a day or two.

 

Re: (civster)

Thanks, let us know.

Let's hope they figure it out. A blown fuse indicates that something is wrong electrically and it would be irresponsible IMO for the dealer to just replace the fuse and send them on their way. Electrical glitches can be challenging to figure out but that's the dealer's job. BTW, I've been on the board for a couple years and have not heard of this problem before. I don't think it is indicative of the car's reliability although it is certainly frustrating in a new purchase!

 

I received a call from my Service Advisor and she informed me that the technician called Tech Hotline and is waiting for an answer.

 

Re: (civster)

As a minimun you need your dealership to consider replacing the fuel pump and possibly the wiring harness. Could be the insulaton was nicked when originally installed. You may want to ask if here is a test he can do to see how many Amps the fuel pump is pulling normally. Good Luck.

Civister, I agree with Jackson.

It would be interesting to see what the tech line says. I hope you have a loaner, it has taken them a bit (3 days) to get this far.

 

Re: (need4spd)

The service manager called and he said they are going to replaced the fuel pump which is on order and they won't get it until Monday, May 2nd. I also have a meeting when I pick up my XC90 regarding buying back the vehicle.

I did get a new (~4500 miles) S60 AWD for a loaner. So far this dealer is pretty good when it comes to loaners. They gave me a 2004 XC70 on the first time my XC90 died, then a brand new (9 miles http://********************/smile/emthup.gif ) V50 T5 AWD when they were working on my seat mirror positions, and now the S60.

 

Re: (civster)

Civistor,

Any update on your fuel pump?

 

Re: (need4spd)

According to the service manager the fuel pump is on backorder but they have a release date of May 5th plus a day or two for them to get it. He thinks the vehicle will be done by Monday, May 9th.

 

Re: (civster)

Civister,

Sorry to see it is taking so long.

All these days help you with your lemon lawl, in terms of how many days out of service.

I can not believe a fuel pump is on back order!

Sorry

 

Re: (need4spd)

In Rhode Island, the dealer has four tries to fix the same issue or the vehicle is in service for 30 cumulative days within three years or two years after the vehicle reached 15,000 miles of ownership, whichever is earlier.

A fellow colleague have a new Acura (TL or RL, I don't remember) and it's main ECU failed. His dealer gave him a rental and he had it for almost a month because the ECU was on backorder. Another colleague got the Nissan Armada and it's transmission blew on the first week. I guess there will always be a bad apple in the bunch.
