Have had diesel fuel put in tank and started till it died. now I'm curious as to the correction and how spendie it might be. And its been sitting like that for 5 years. was a very good car prior to that.

What is your question?

It was about 4 gallons and like I said has been in there since 2014. What would be the best avenue to fix?? Thank You.....

How long has your 1999 Ford Taurus had this problem?

since Aug 2014
