There is another known problem with Fords, and particularly Escorts. I thought it was an issue with a limited number of years in the generation 1 scorts, but I could be wrong, so you would be well advised to check it out... there is even a class action lawsuit against Ford for this problem. There is something called a "TFI", but I don't recall what it stands for. Some ignition module. It gets too hot ant it burns out, so to speak. When this happens you get all the fuel your engine can handle, the power to run the starter, and everything seems fine, but the engine doesnt kick over and start. This is because the spark is never coming from the plugs and thus there is nothing to ignite the fuel in the cylinders. A simple enough way to test this would be to check for a spark. You can do it in the dark by pulling a wire out and looking, or use a simple circuit tester. If your pump is working, you eventually smell fuel in the engine compartment, and your starter motor is engaging, then I cant think of anything else except lack of spark that could be causing your problem... unless it's a serious problem inside of your engine, but I doubt that is the case.
