    do you have the correct psi on fuel, also is there gas deposits left in there. I don't know that much about Porches, so is it injectors or carb. is it in the correct timing.

SOURCE: Recently looked at a 1997

Personally, if all feels like it's working as it should, I wouldn't hesitate if the price is right. Have transmission inspected and serviced soon if concerned and at regular intervals to give it the best chance at performing good for a long time. With that said, let me ask this. Did you research any other vehicles similar to the Taurus, but manufactured by other makers? Very few, if any, don't have some kind of known weakness that will cost money later on, whether it be transmission, or engine related. It's just a fact of life with all these lightweight materials and electronics they use for building vehicles now. Go to the library and look for a book called " Lemon-Aid" by Phil Edmonston, or stop at a book store and buy one. Very good reference on vehicles and what problems have been reported etc as well as other related info. You'll find problems with everything, but some models have less, or less expensive repairs down the road, but usually cost more to buy up front. If your really concerned that much, get a quote from dealer or shop you trust on how much for a transmission service and inspection prior to buying it.

Car has been sitting Need to run.

The old gas will cause hard starting for sure as it is 15 years old but if you don't have very much in the tank you can mix in some new gas.

Car has been sitting; will turn over but won't start. Used starting fluid and car starts but quits. Won't fire without starting fluid. There is fuel in the tank. Help!!

My first thought is to check the fuel pump operation.
Check to see if fuel pump is getting power.

This is how I check the pump.

Usually there is an in-line fuel filter that can be removed.
While its removed...bump the starter to see if gas shoots out the gas line.
If not, there might be a clog at the pump...or the pump needs replacing.

Hope this helps...

I have a 1999 gmc sierra with (as of 30 days ago cat. converter, fuel pump and filter, cap and rotor) changed in garage. regular oil changes, tune ups as of 8 mths. it has lots of cranking power, but...

If i understand you right the truck has been sitting for two years.If it has been sitting that long without running or moving the gas has turned to varnish...I suggest that you drain and refill the fuel tank,and replace the fuel filter located on/in the frame rail on drivers side.

Theres a gas tank leak comining from the top of the gas tank. what could this be /

Not knowing your milage or what part of the country you live in if they use salt on the roads. The leak is coming form the three fuel lines going into the gas tank and fuel pump. The fuel pump is inside of the gas tank secured by a large slip ring seal. From the years gone by these lines rust and since they are under pressure they will leak through. You will have to drop your gas tank to get to this. This is a ugly all day expensive job. Replace the fuel pump which comes with the new seal and fuel lines assembly. I could sit here and tell you the step by step procedure but that will take hours. The very best thing you can do is buy a Haynes repair manual for your car and year at any auto parts store @ Advanced, Autozone. Read the step by step in the manual. I have used these for 40 years with all my vehicles and saved tons of cash in labor costs. Be prepared to replace the gas tank straps and additional fuel lines depending on how bad the rust is.
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me.

Difficult to start have to keep pumping the gas been sitting 8 m

To stop this from happening in the future, add fuel stabalizer to fuel tank when you store it. Run your car for 10 minutes before shutting it off. It would also be helpful to fog the engine also before storing. You can get fogging oil at any auto supply store. As for your immediate problem try adding carburator cleaner to gas tank.

Car started but after 5 seconds stopped. Cannot start it again. It turns over but acts like there is no gas flow. It may be the fuel pump?? Any suggestions. Where is the fuel pump located?? Thanks Jim

this sounds like the fuel pump may have quit, the pump is electric and located inside the gas tank, there may be an access plate under the rear seat cushion, most have this plate, if this year doesn't the fuel tank must be pulled.

here is the part number for the original factory style pump

DENSO Part # 9510001
OE Manufacturer $128.00

I just tried starting my 1986 Porsche 944 its been sitting in storeage for 3 years and havent started it since, and now i bled the gas line to get rid of old gas and drained the tank and put more gas in...

its the fuel pump relay, take the petrol in hose off (just over the air inlet manifold) and start it up, if fuel comes out then its not the fuel pump or relay, when you say starter fluid what do u mean?
