OK, we've replaced the broken fuel pump, and replaced the fuel filter, spark plugs, spark plug wires, distributor, rotor button, and ignition coil... Fuel is getting to the fuel injection bar, but no spark is coming off the coil. Any ideas? Jeep turns over, but it is obvious that there is no spark - and we've tested for spark and have none... Any ideas? Only other things I can think of would be faulty fuel injectors or the ignition computer. What would cause failure to generate a spark?
