Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less.draining the gas in a car like this is not gonna be good enough. So you are going to have to remove the tank and change the screen inside the tank and have the tank hot dipped to remove all the old that and scale that will be in the tank. I have done about 5 cars like this and they all need the same thing. Anytime the cars sit longer than 3 years. Hope this information helps , Lou.

Can show in picture where it is located? I will try it tomorrow.

Maybe you misread my post. The whole tank has to come out. The tank is in the trunk. It is between the back seat and the trunk. Remove the carpeting and you will find the tank. Also the fuel line has to be removed from. The bottom of the tank.

I think i found the problem. I open the fuel accumulator. It was clean and look good. But rubber hose coming out o it was melted inside it was clogged. I am going to get new accumulator tomorrow to see what happens.

Ok. Good luck. When we did these types of repairs we replaced both pumps , removed and cleaned the tank , replace the tank filter , the fuel filter , clean all the fuel injectors , replaced all rubber lines , cleaned fuel distributor and also Checked for vacuum leaks. Hope you get this going. They are great cars. As long as they run right. :)
