I have a 95 bobcat 763. I had been turning the key on and manually pushing in the fuel solenoid to start. Over time it has stopped working. I replaced it and the timer relay harness. Turning the key the solenoid does not engage. I changed out each of the 4 relays and the solenoid still does not do anything. Could it be in the ignition switch or something else I'm missing. It will turn over and all the lights do come on. I also have checked the battery and tested which all are good.
