Help! Volvo Penta Md5b?!?!?!?!
Ok, I have blead the fuel lines, its getting fuel, I found the fuel kill lever and its open. There seems to be good compression?!?(havent compression tested it yet),took out the injector and cleaned it(it looked pretty dirty, but not horrible), Intake is sucking air like it should. The motor just cranks and cranks but doesnt start. Ive event tried the old wd40 in the intake trick, still nothing. Ive gotten some black smoke once and it seemed like it was trying but didnt start. Im at a loss guys. Did I miss something? The motor sat for probably 3 or 4 years, so maybe bad fuel?!? I added about 3 gal of fresh diesel to the tank and the tank cant be more than about 8- 10 gal. and was only about 1/4 full when I started. could the fuel be the problem or is there anything else to look for? Im ok with rebuilding it if I need to, but i dont want to yank the motor to find it was something simple to fix. Any help will be appreciated greatly! thanks for your thoughts!
