how do you fix old old varnish smellin gas in fuel system? 200 78gt

posted by  someone claiming to be will on  Sun Apr 22 12:26 CST 2001 [RELATED]

i got the gt this weekend, changed the oil,coolant, and put some decent used plugs in squirted oil in cylinders etc. the gas gauge read empty, so i put some injector cleaner and 5 gal fresh gas in. when i went to start the motor made a air whining sound after i finished cranking it over. after about 10 tries cranking the motor started to catch and almost run for about 3 or 5 secs. it then would not start again, the best i got was another sec or two. well i noticed a varnish smell not gas so i imagine there was some bad 2yr+ gas in the system. is this keepin the motor from going? have i ruined the fuel distributor or injectors or better yet the engine by tryin to start the motor? any suggestions on what my next step should be would be greatly appreciated. thanks will

    /// You may have to pull the injectors and soak them in gas. Replace the injector o-rings. Use only high temp o-rings or Volvo parts. If the gas evaporated the injector parts will be stuck.

    As the previous post said the injectors will not work once removed from the head unless the air plate is lifted. Careful if the plate is hard to lift. You will be creating extra work if you bend the lever to the fuel distributor.

    Worst case the fuel distributor is frozen. It can be disassembled.

    Have had that problem. Drain the tank and use only good high test stuff once you have the old stuff out. You may need to change the fuel filter a time or two as it is most likely clogged. Also, if your filter hasnt been upgraded to the newer larger one, do it.

    Do this first and see if it keeps going. The air flow sensor may be gummed up also. You can purge the system also if you remove the injectors and place them in separate cans and lift the air flow sensor with ignition on. Remember, this can be dangerous with spark and fire sources, but it will push a lot of stuff through the system. A little injector cleaner added will help.

    Get rid of the old fuel first---it will just mess you up for a longer time.
