Hello All,

My 2000 Buick Park Avenue with 210,000 miles has the original fuel pump and ignition control module. I read through the threads and had a question. I am having no problems. However, considering the high miles, and that fact that the car is 13 years old, would you recommend changing out either the fuel pump or ignition control module?

Thanks!

I think switching out the fuel pump to a DELPHI is a good action if you plan on keeping the vehicle for at least 3 more years. The DELPHI fuel pumps have some updates to include more reliable fuel level reporting and increase amp draw availablity.

Your fuel pump is held in place by a metal ring. There is a good chance that ring has major corrossion. If you select to replace the fuel pump, you may want to prepare early by spraying the fuel pump ring with PB Blaster (or equivelant) to reduce the effects of the corrosion. Make sure you order a new ring with the fuel pump. Rockauto.com has solid prices on DELPHI fuel pumps.

My 99 Park Ave had 250k on it with the original water pump. fuel pump, alternator, starter, I sold it and it now has 300k and still none of the above have been replaced

I would not change the ICM.

I am of a mixed mind when it comes the fuel pump. On one hand, I always work by the principle of "if it isn't broke, don't fix it". You never know what else you will mess up in there. On the other hand, the fuel pumps on our cars have a tendency to fail, so if you plan on keeping the car for 2 to 3 years or more it might be a good idea to change it. Particularly since the weather right now is more conducive to working on your car. Flip a coin. Heads you change it, tails you don't. Let the fates decide.

Thank you for all of your responses and the tips on how to replace it. That is interesting about the updated Delphi pump. I am now leaning toward replacing it this summer. Other than using a brass punch to remove the ring does anyone know of a reasonably priced wrench that will work? The GM one is really expensive and I cannot find a generic replacement.

I use a brass punch, but tap it on all sides as you are loosening it. If you just hammer on one spot it won't budge. Also, don't forget to get a new O ring to seal the pump to the tank. They only cost around $4 but a lot of people don't think about it until putting things back together.

punch and hammer. i replace the pumps before hand, ive had the things go out in the middle of january and you freeze while you wait for the tow.

you might have a panel, my 03 monte they did they started in w-body at least in 2000

Its got a panel...my 99 Park had one and my 2000 Lesabre has one

Having that access panel turns a big job into a little job.

I have a Kent-Moore J-39765 wrench made specifically for removing the fuel pump retaining ring, this tool and a 1/2" drive breaker bar and the job is a snap.I picked it up on E-Bay for $75, I'll pass it on to you for $65 if you're interested, private message me. I don't check the forum every day, doesn't sound like you're in a big hurry anyway.
