tonight i was driving pretty hard on the pedal. a little street racing maybe :grinyes: and well as i pulled into the BK lounge the car stalled. i tried starting it and as soon as i let the revs drop below 1500 it stalls. i popped the hood and had a friend start it and it sounded like there was grinding coming from the supercharger. im hoping it was just the coupler or s/c bearings but idn. any ideas? could it be and problem with the pistons or heads or anything? or s/c itself? idn and im quite scared this time around ha. any ideas let me know

I would try taking the belt off of the SC and see how the car idles. If it is still grinding you may have launched your engine.

That doesn't sound good. When was the last time you checked SC oil level or did an oil change? With the SC drive belt off as suggested move/spin the SC pulley rapidly by hand. When the snout bearings go or get bad you should be able to feel it or tell. Feel for binding, poor movement and listen for noise.

well i took off the sc belt and spun the pulley, and although there was a pretty decent amount of slop, i felt no grinding. it still wouldnt run without the sc belt so i just decided to have it towed to our local shop. the shop said it was the fuel pump resistor. the only problem is, the resistor is on national backorder. no one has one. i dont know what to do as of now.

and as for the grinding, i think it was just due to the fact that the engine was stalling,cuz it was only doing it at the REALLY low RPMs as the engine was stalling. i figure it had something to do with the bearings in the sc cone. they did say that will need to be replaced very soon.

but as for now, does anyone know where i can find a fuel pump resistor?

The part number is 88951182 and GM is showing it on back order, but I live in Flint Michigan and checked with many of my local dealers and they show stock. Have you tried more than one local dealer?

also, the resistor wouldn't cause any kind of grinding or scraping noises so you may still have snout bearing/coupler issues.

Also, try PFYC.com.

Plus you can run the fuel pump resistor bypass if you need the car for wheels until the part arrives.

ya i know theres something wrong with the coupler and/or bearings.

i checked a few web sites for the resistor, and our shop called around and said that they cant find them anywhere. ill check pfyc and if i cant find any i think ill try finding a low mile used one from ed morad(he specializes in 3800 cars). his place is 10 minutes from my house so that might be the easiest.

That is nice that you are only 10 minutes away from his warehouse.

LUCKY! I want him 10 minutes away from me!

You should also get a good used low milage supercharger snout and bearings from him. Then thrown in a zzp coupler.

how hard would it be to install a new resistor on my own? and if i can do it, how do i do the resistor bypass so i can drive the car home from the shop its at? and is that safe?

The resistor is a DIY job. See link below for the bypass procedure. It is safe for a short period of time. Some of us went a few weeks until the part came in.

Do we know what the resistance of the resistor is. It is possible to make up one and not worry about the national back order on the fuel pump resistor.

Not off the top of my head but it is up there in wattage. Plus you would have to waterproof or weatherize it. See link which has an illustration of one.

Making it waterproof is not a problem, the wattage is also not a problem. There are resistors that are in a metal enclosure that are 25 watts of dissipation. That I would think should be more then adequate for the power dissipation. If I can get the resistance I can make them.

The official GM fuel pump resistor kit is here. Don't replace your fuel pump if you don't need to. Carry this spare with you and never worry about getting stranded by a failing fuel pump resistor module. This is one of the most common problems on 1997-2003 Grand Prixs and is easy to fix if you know about this kit and have one on hand. With our repair kit, you can do it yourself and not have to rely on a dealer or end up stranded.

Mistake? Or Marketing Gimmick? :lol2::screwy:

ya i was considering that one on pfyc. anyone know if i should get that?

You mean the year range? The problem is 2001 and up do not have a fuel pump resistor and in the engine compartment fuse box no fuel pump speed control relay. Also, it should emphasize with L67 engine only.

As long as you have a '97-'00 there should be no issues with the one from PYFC.

Yep Bob, thats what I was getting at. Just the way they worded it seems to make me think they are just trying to sell them to anyone with a 97-03 Grand Prix as a magical part that can keep you from being stranded. Like we'd want to be climbing around under the car along side the road to replace a resistor when we can just bypass it and replace it in the comfort of our own driveway is beyond me.

I agree. :grinyes:

Poor marketing but overall PFYC (Parts For Your Car) is a good parts source.

alright. one more question. the car is at the repair shop, and they already removed the resistor. can i drive the car with the resistor bypass even without the resistor even installed, or do i need to have it reinstalled first?

No the resistor does not need to be physically installed as long as you do the bypass and it is done correctly.

While you're waiting for your resistor to come in, make sure you keep the tank above 1/2 full. Running constantly in high speed mode can cause fuel starvation issues on a low tank due to the volume of fuel being returned to the tank.

thanks a bunch everyone. apparently the part has been replaced with a newer model, causing it to appear out of stock at the dealers. its a newly designed resistor that had a new part number. our shop was able to order one and they put it in, although i kinda wanted to do it myself. thanks again

could you get us the new part number?

ya ill try to get it by friday. sorry for the wait, i wont have a computer till then :frown: and i dont have the number right now. ill let you know tho when i can

The most current number I can come up with is GM# 88951182, but GM shows no stock according to my local dealer buddy and no expected date for availability. This normally indicates a supercession is in the pipeline, and he's going to look into it for me and let me know what he finds out. There is still stock out there, as several local dealers in my area show stock on the above part number.
