Hello, pulling my hair out on this one. I have a 93 fox that out of the blue will not start. Started out fuel pump runs continuously, changed out relay and different computer I had laying around (same computer.) With the other computer the pump stopped running continuously good but still no start not even a pop with starting fluid. I have 39lbs fuel pressure, have spark, swapped out distributer, new plugs, coil still nothing. I have fuel, spark and air. injectors are pulsing also., fuel pressure during turn over. Car tuns over great. oh, yah new fuel pump also. Car ran perfect before no issues at all. Hope I can get some other ideas. Thanks

Have someone squirt some starting fluid into the air intake as you try to start it.... If it starts, you have a fuel problem, if it doesn't its probably electrical...

Pull codes. The CEL only comes on with emissions related codes so there can be other codes and no CEL indication.
