reviving a hibernator 140-160

posted by  someone claiming to be TJ Conaboy on  Fri Nov 8 16:38 CST 2002 [RELATED]

I am helping out a buddy put a D-jet car back on the road, 1973 144. We can
get it to start with starting fluid, sometimes it will run on it's own, but
only on 2 cylinders. If you give it gas it just dies right out. Checked the
fuel tank and changed the filter. What else should I look at?

    If it runs on 2 the trigger points in the bottom of the distributor may
    need to be cleaned. If they are clean then check the injectors.

    I assume the fuel pump is running OK......

    Before attempting to start a car that has been inactive for so long, it is a good idea to drain the old gas and replace it with some fresh fuel. Remove the plugs, squirt oil into the cylinders, while the plugs are out turn the engine over enough to get the oil circulated to prelube the engine. Preform a compression check to see what condition the engine is in. If the compression checks OK. Remove the injectors to see if they squrit fuel. While the injectors are removed, replace the injector seals. Most likely the old Volvo will have an ignation problem of some sort, that will have to be fixed. If you get it started let it idle with the heater on till warmed up, check temp. Make sure it will not overheat. If it has a lack of power, most likely the cam is worn.

      Again, do EVERYTHING that Oops said, then chk. the fuel pressure. Injectors don't work well if pressure is down. Tom

        To which I would add:

        Nin-firing injectors are often just lightly stuck shut with gummed fuel. Before pitching the $100 injector for a new one try freeing it first. Pull off the entire fuel rail with all wires and hoses attached. Turn the key to the 'on' position a few times to build up pressure (you should hear the pump run briefly each time). Leave the key on. Then under the hood observe the injectors as you push the throttle open. They should fire in pairs back and forth as the throttle opens (the high tech 'accellerator pump' function). Look for any that aren't spritzing. There is a small metal pin on the end of each injector - if you press it in gently with a small pointy object (like a finishing nail) it will break the stick and most often resume a fuitful life. Run some FI system cleaner through the gas to prevent them from resticking the next time it sits for a few weeks.

          Most of the problems I've had with these cantankerous beasts (and I say that with a great deal of love in my heart) are the electrical connections. The insulation cracks, they get wet, and changes in the weather can make them more irritable than me. Check all the ground connections, too-- I once had a '72 die on me and after hours of fidgiting with it finally gave up and had it towed home where I realized that the injector ground cluster ground on top of the rear of the intake manifold, although firmly bolted down, was not making a connection. This may not be the case with your car, but electrical connections are oftentimes the culprit.
