91 Bonneville SSE 3.8 Fuel Filter location Help...

Aug 30, 2004 6 Replies
  1. I have a hard time starting my Bonneville after it sits along time, I know its not good to pump the gas before and while starting but thats the only way it'll start. Now after I get it running, it runs very very sluggish like its starving for fuel. I want to try replacing the fuel filter first before the fuel pump incase its not the pump. I never done this before, so I do not know where abouts the fuel filter is located. Can anyone help me please?
  2. My Harmonic Balancer is shot also. Would that have anything to do with way the motor runs the way it is now?

Thanks for your help... snipped-for-privacy@wi.rr.com Norm



The filter's under the car, near the back driver's side door. If you've never removed it before, don't expect much luck. Start now with penetrating oil on the fittings. Hit it every day for a week. Then get the best wrenches you can afford and hope for the best.

There's a real chance you'll twist the fuel line rather than rotate the fitting relative to the line.

I keep my fittings covered with bearing grease.

How are you certain about the damper? Can you turn the outer pulley by moving the belt? If you can feel & see the damper turning to the limits (and clicking when they hit), yeah, it's a shot damper.

Not tough to remove through the wheel well, but you'll need a good quality impact driver and plenty of compressed air. XXXFactor9 wrote:

Robert, Yes I can move the outer pully back and forth and clinking when they hit with a good 5 to 6 inches of play in between. Can I drive the car with a shot damper without hurting anything else? I only have this one car to go back and forth to work, and I can't get it fixed for other 3 weeks for I only get paid once a month. Thank you for telling me were the filter was located...

Do as the other poster mention & flood the fuel line connections with oil. If you got one fitting on one line to turn alright then you can loosen the filter on the other line if the fitting is rusted to the line. Just hold the fitting with a good GasLine Wrench and use a second wrench on the filter itself & then unscrew the filter.

This is what I had to do for a couple years when my line rusted. Got new lines now.

Yes you can drive with a bad balancer as one poster mentioned doing so back in April. Then one day while driving there was a bang - bang a lang, flap - flap bang ! noise and the car came to a halt.

The harmonic balancer came off, broke the crankshaft sensor, the serpentine belt wrapped around something & broke whatever piece that was.

Check a junyard for a balancer price if $$$ is a problem.

Good Luck...

You can eventually ruin the crankshaft, and the main bearings. Not to mention throwing belts, losing the water pump, PS, and ALT. GW

Yes, the fitting's are rusted over and not budging, I'll try to loosin them again this weekend after I spray the fittings with oil everyday. Thanks for the info HarryFace on the balancer and that sad story, I'll check junk yards around here for prices and get it fixed right away. Don't need that happining to me.

Thanks again for all who helped.

And HarryFace a big thanks for the second time helping me, and a time before with the starter and celenoid, which is now fixed...
