Re: Volvo MD7A Not Starting
Start with the easy stuff, it sounds like the engine is no getting fuel.
Are you sure that the shutdown is really in the correct position, I have found this to be the cause a suprising number of times.
Are you sure that you are getting solid fuel at the injectors and no air? You really need to bleed all of the air out which can be time consuming and frustrating. Any air in the injector line will prevent the injector from popping off which means that you will never purge the air and you will be in a never-ending cranking cycle. If you ran your injection pump dry, they hold a large volume of fuel and can take quite a while to refill (one of my engines holds over 1 gallon in the IP, don't worry, your volvo holds significantly less) If you have any questions as to whether you bled properly, I would suggest that you post exactly what you did so that people can give you feedback. Also, since you have replaced the filter and broken other connections, you should really make sure that you haven't created an air leak, especially on the suction side.
Beyond that, answering SchockT's questions would be helpful.
