1991 Buick Regal Limited (3.8) ABS light blinking

Well, a buddy of mine had this car, and it began to leak fuel badly from the bottom of the tank and he decided to get another vehicle. he decided to sell this "heap" to me for $25.00, as it turned out the hole was fixable, and it runs like a brand new car, however the ABS light blinks in 1 second increments constantly. Brakes are squishey... air in lines/calipers? vehicle has 4 wheel disk brakes (if that helps). would an OBD2 reader reveal an error code, though the check engine light is not on?

    rejakwilson: thank you for the speedy response, so what you're saying is basically do a full brake job, right? I would have suspected it to be an electric problem because it is not a steady light.

    chemmierun: I doubt it's a wheel bearing since the vehicle drives free of noise and vibration, I also jacked up the front end to feel for any wheel bearing play (on all four) and found no sign of a wheel bearing problem, (also since there are no wheel bearing sensors)

How to change fuel filter on 2005 town & country van.

Unfortunately there is no easy, or inexpensive way to do this on your vehicle. Chrysler decided to make fuel sending unit that contains the fuel pressure regulator, the fuel filter, and the fuel pump along with the level sending unit all together and located it inside of the fuel tank. The whole tank has to be dropped out of the bottom of the van and the whole assembly changed.

What to do if you think you put bad gas in your tank

Hopefully your vehicle will have a drain plug in the bottom of the fuel tank*: remove this & drain the fuel.
With the plug still removed flush about 5-10 litres of fuel thru by putting in thru the tank filler hole as usual.
Replace the drain plug and put a FULL tank of fuel in (this will dilute any residue as much as possible)
*In the case of no drain plug the fuel tank will need to be removed & fuel drained out thru the filler neck, drain fuel, replace tank & procede from the 'put a FULL tank of fuel section of this instruction.
If the vehicle has been started with the bad fuel remove the fuel filter.
If the vehicle has an electric fuel pump* (more modern vehicles ie. Post 1985 [some vehicles still had & still do have mechanicle fuel pumps]) turn the ignition on with the fiter not in place, vthis will flush fuel thru the fuel lines pushing out the bad/old fuel. Take care as the fuel will be under a fair bit of pressure & "sqirt' out.
*If it is a mechanicle pump this can not be done in this way.
Replace the fuel filter with a new one.
Bleed the fuel system & start the vehicle.
Allow the vehicle to idle for 10-15mins before going back to your usual driving.
All shld now be ok but it is a good idea to routinely inspect the fuel system for leaks over the nxt 10 000km or six months (wich ever is earlyest) as in the case of puting petrol in diesel or diesel in petrol the different rubber and plastic items (such as 'o' rings) can begin to deteriate & leak in wich case they will require replacement.

All the best & I hope this is of some help & it works out for you...

2004 Hyundai Sante Fe running rough after fuel light came on, check engine light came on.

Someone will need to have the computer scanned for trouble codes to proceed with troubleshooting the problem.
As long as the check engine light is on some of the sensors and components may be bypassed.
Its possible you pumped some dirt or contamination from the bottom of the tank into the injectors.

Leak on bottom fuel tank

There are some products which will repair a fuel tank. It depends on the leak.

Some of the products require removing the tank, adding the leak chemical and swirling the mixture inside the tank. Other products are like JB Weld which could work, but there are specific chemicals just for this job.

If you have rust on a 1999 vehicle, it can cost you less to replace the tank new, than to buy chemicals and lose gas when they do not work. Rust is especially hard to guarantee a repair on. Fix one place and another leaks a day later.

Check out the Internet for new tanks. It will be harder to find an old tank because most are ripped off before the Salvage cars are allowed on the lots.

Radiator shops sometimes do this repair.

I hope my solution is helpful.

Gas leaks out of my gas tank recently had a fuel pump put on could that had caused the problem

Yes, it is a very good possibility that replacing the fuel pump did cause the fuel leak at the fuel tank, especially if the vehicle did not leak fuel from the fuel tank before the fuel pump was replaced, and the seal to the fuel sending unit/fuel pump assembly might have slipped out of place or was damaged when the fuel sending unit/fuel pump assembly was installed onto the fuel tank, the fuel lines might not be properly attached to the fuel sending unit/fuel pump assembly, the filler hose to the fuel tank might not be properly tightened, or even damage to a fuel line, the fuel tank itself, or a vent, from not properly installing the fuel tank into the vehicle. Those would all be a problem with quality workmanship and if any of those reasons are responsible for the fuel leak and the repairs were done at a repair facility then they should warranty the repair for their mistake at no additional cost to you.

However, road debris could also have damaged the vehicle and that would not be anything that would be covered by a warranty, and someone who is qualified and objective should inspect the vehicle to determine exactly where the fuel leak is coming from so that a proper course of action can be decided.

Fuel tank leaking how to solve problem gas is not pouring out but is seeping through bottom of tank There is fuel leaking from the top of the tank, is it a fuel overflow release or is the seal on the fuel...

If your gas tank is cracked or has a hole in it, you have to drain the tank, remove the gas tank and replace it, or have it repaired (if possible). If the gas tank is just leaking from the top and dripping along the side and to the bottom, you will still have to empty the gas tank, and remove it to get a good look at the condition of the gasket. It is not uncommon for these gaskets to become cracked or fragile over time because of the harsh chemicals and cleaning agents used in unleaded gas. If you do decide to have the gas tank removed, I would recommend replacing the fuel pump and fuel filter if your car has high mileage. Please rate this response if you found this helpful.
