hey guys...I have a 1991 twinturbo. I have had it garaged for nearly 2 years and didnt really get a chance to start it. Just got busy with soo many things in life. the car worked fine before i garaged it..but now it wont start up. I have checked battery its ok....changed fuel filter..changed oil. the engine sparks up but wont run...Any suggestions on what the problem may be?..please help as I now do want to start driving it again.
