Nissan Sentra Won't Crank

Q. Hello, my name is Justin. I drive a Nissan Sentra 1.6 liter manual transmission. When I get in the car and go to start it, I turn the key twice to let the fuel pump run the allotted 4 seconds then turn the next time to start it. But all it does is click once. The clutch is engaged so that is not the problem. I have tried a new battery that is not the problem.

I have checked all the fuses. That, again, is not the problem. I have also put a new starter in. again will not turn over. I have run through all the wires, positive and negative, only clicks once. I can push start the car and it runs fine. When I turn the ignition while running it makes the grinding noise like any other car would.

I am at a loss. I have had to catch a ride to work for the past two weeks and even the Nissan dealership couldn't help me out. I don't have the money to pay for labor so I am hoping to fix the problem on my own which would seem easy to do. But I just can't figure out what the heck is wrong with it. Can you please help me out?

Thank you kindly,
Justin

A. The Nissan Sentra starting system is about as basic as you can get. Since you failed to tell me the year of the car, I can only offer some general suggestions.

First thing to do is check for power at the starter. With a test light, see if there is power at the black/yellow wire at the starter with the key in the START position. If there is, the starter is bad. Now jump the terminals in the Clutch Interlock Switch on the clutch pedal. If the engine starts, you have a bad clutch switch.

Check for power at the black/red wire. If there is no power there, you have a blown fusible link. Check for power at the black/yellow wire coming out of the ignition switch with the key in the START position. If there is no power there, and there is power at the black/red wire, the ignition switch is bad.

Check for power at the both black/yellow wires at the starter relay with the key in the START position. If there is no power there is an open wire between the ignition switch and the relay. Finally, check for power at the black/white wire at the starter relay with the key in the START position. If the relay clicks and there is no power at the black/white wire, the starter relay is bad.

That's about it. This will pinpoint the problem is it is not an intermittent problem.
