I bought the car when it was not running at the time. The previous owner stated that the problem seemed to be gradual and became worse. He said that at first he would just have problems with it losing power while on the freeway. He would try to accelerate and it would just sputter for a minute then pick back up. After a while it was happening even in the city and eventually wouldn't even start on a regular basis. I suspected the fuel filter at first and he claims to have already replaced it. I still plan on replacing the filter prior to testing the fuel pump though just to be sure. I have verified that I have spark to all of the new plugs I have installed and that the points are correctly gapped and the distributor cap is clean. At this point I am fairly confident that the issue is not spark. When I did replace the plugs and used a little bit of starter fluid I was able to start the car but I had to hold the pedal down to the floor the entire time or it would die. I only got one half way decent start though and after about 30 sec's it died. I also verified that I have fuel running up prior to the injectors but have not tested those yet. I am more than happy to get any other suggestions on what could be wrong though. I figured I would get the filter ruled out next and then the fuel pump and then the injectors.
