Ronnie, check and make sure that your EGT probe is not shorted out-That will cause blown plug and no ignition issues. Try and start it with a standard glow driver and see if everything else works fine. Connect the glow plug wires from the ECU together to fool the ECU then attach a seperate glow driver, turn it on and initiate a start sequence. If it starts up you will know you have a issue with the ECU driver circuit. A short anywhere will cause the plug not to light. Check your starter to make sure that you dont have a short in anything there also. I just went through this with a RAM-turned out the little preload device (that little hat shaped thingiy on the end of the starter with a ball bearing in it) on the end of the starter had come loose allowing the starter motor to come too far forward and short out enough to fault the glow sequince.
