I bought my Lexus SC430 used in 2008 with 53k miles. Stored both winters. Took out of storage in March. Ran perfectly until early May 2010. Began to start very rough - crank for 6-8 seconds. Sometimes would start then, other times only on the 2nd try. Once started, no problems. Took to Lexus dealer and they diagnosed low pressure from the fuel pump - suspected check valve - had it replaced. Took home and brought it back since it was not fixed. They diagnosed 3 leaking injectors so those were replaced along with a fuel dampener. Did not fix problem. Now they say that 4 of the remaining 5 injectors - which were not leaking when tested last week - are now leaking. Want to replace injectors saying that there is a lot of sediment in the gas tank that has caused this problem, so they will also clean the gas tank, replace the fuel screen, the fuel pressure regulator and fuel filter.
They say that the sediment could have been in there before I bought it since these are typically stored for half the year.
This is getting very expensive. Does this diagnosis make sense? It is hard starting about 25% of the time.
