Clutch interlock should only prevent you from cranking the starter without the clutch depressed. You should be able to push start with this malfunctioning since the rotating motor is doing just what it would be if the starter worked.
The manual transmission has a starter interlock which prevents the engine from cranking unless the clutch pedal is depressed
That's where it is when you push on the clutch pedal and it's called a switch.
? But u can push start it,it work for me
the clutch has to be pushed in to start. there is a switch under the dash probably knocked it out of position. while changing cable.
Because you have to have the clutch depressed to start it. They came factory with a clutch safety switch that will not allow the engine to start unless the clutch pedal is pressed to the floor . NOT. the clutch safety switch only allows the starter to be energized... If the glow plugs will cycle then the truck can be pulled to start. When my starter solenoid was bad I pulled it to start.
Clutch safety switch
Just push it a few feet with the ignition switch turned on and pop the clutch.
I have a 2006 Nissan frontier and on mine the clutch safety switch is located at the very bottom of the clutch pedal travel. That is to make sure you push the clutch all the way in when you start so you can't accidentally crank it over in gear and drive into a wall (Seen it done twice by two different coworkers in an older dodge w/o the clutch switch!!)
the reason is that there is a switch at the bottom of the spring by the clutch that is a safety switch so you don't start the car up in gear. either the master cylinder is leaking and by pumping it tells the switch that it is not in gear or the switch is bad and youre just hitting it and knocking the bad connections back to their senses, or you have a bad cable that has stretched past it life . try having someone push down on the switch or hit the switch while you try to start it. if the fluid is too low it will not start or the car will start and while you are driving it will lock up and not shift because of low pressure in the master cylinder for the clutch because of a bad master clutch cylinder. there is an adjustment for the spring cable when you push in the clutch. your clutch or cable is at its life end.
The switch is under the dash connected to the push rod for the clutch master cylinder.
the ignition switch is shorted or wires shorted at the switch. Your clutch safety switch is just doing it's job and completing the circuit when pushed.
you may need a new clutch or there may me some sort of sensor or switch that is bad
