Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you!
Since you reached in through the window to open the door, most likely the factory alarm is the issue. If using the mechanical key in any of the lock cylinders is not working, then most likely the tamper switch that connects to the back of the lock cylinder that turns off the alarm has fallen off.
How handy are you? Are you able to remove the door panel to inspect the tamper switch and reconnect them?
Here is a image of what it looks like
Ok. Cool. I share a link that has a image of the tamper switch. See if you can pop a door panel off and see if this tamper switch is secured onto the back of the lock cylinder. If it's not there, look for it and snap it back on and use the key to turn off the alarm..
Let me know how you make out...
Doesn't matter which window. Once the factory system is armed, it can be set off by any door you reach in and open.
You pulled a door panel off and checked?
With everything closed. Hood and doors.
If you lock the car with the key, does the security light turn solid for 10 to 20 seconds?
now unlock it with the key and open the door and see if the engine turns over
There is no horn or lights flashing right?
Then you may have a starter issue.
Can you locate the gray connector that goes to the starter? It's under the air filter air box
No...The fuel pump would only come on for a second and then turn off since it does not see engine revolution
The fuel pump is a least of your problems right now.. So don't focus away on the real issue. The engine is not turning over. We need to focus on that.
Ok.. Do you have a volt meter?
We need to see if that gray connector is getting power when the key is turned to the Crank Position. If it's getting power, then we know you have a starter issue.
Do you have a test light?
If it's getting power, then you have a starter issue.
If you are not, then a volt meter will be required for sure to do more tests.
You tested it with the key in the Crank Position? What did you use to check for power.
Then we are going to need a volt meter to start tracing why the starter is not getting power when the key is turned to the Crank Position.
Is the car a Stick or Automatic?
If you put the car into neutral and hold the key in the crank position see if the engine turns over. If it doesn't, move the shifter slowly into park and wiggle the shifter.
Can you get a volt meter?
If you were not getting any power to the starter then it is not the starter.
The issue does not sound like its the alarm. That is why you will need a volt meter.
Can you get one?
ok I will be on and off line this morning, then I have a Family event after 12 noon EST.
If you turn the key and hold it in the Crank Position, you should have battery voltage at the starter. If you don't, then you need to back up through the circuit till you find power.
If your getting power at that gray connector, then it would sound like a starter.
When you used the key to set the alarm by locking the car and the security light turning soild then blinking and using the key to open the door and alarm not sound, it is not a factory alarm issue.
If you have a after market alarm, that certainly can keep the starter from operating also. Is this a Nissan remote you have? Did you try changing the battery in the remote?
Oh! If you have a after market remote, then you have a aftermarket alarm. Can you locate the after market alarm module under the drivers side dash?
Then lets wait for the volt meter to go through the circuit
You got it
Cool. I will be online around 7 pm EST and then be online till 10 or 11 pm.
Can you wait till then?
I am currently working.. I will be leaving work in about a hour.
What time will you be home after your meeting? I can instruct you on what to check so when there is day light you can check it tomorrow if you like?
Ok.. This is what I will do when I get home. I will extract the wiring diagram for the starter for your car from the factory service manual. I will the make notes on what you are to check. I will also try to add images of relay locations to help you.
This way when you get home, you have info to follow.
Just had to fix a internet issue. Let me work on getting that info for you...
You want to locate E61 relay and check for power at pin 1 & Pin 6 with the key in the Crank Position.
Pin 1 should have power with key in the ON position, Pin 6 with the key in the Crank Position. See if Pin 2 has continuity to ground at that relay as well.
If you jump pins 6 to 7, the starter should engage when you turn the key as a test also.
let me know how you make out
It would be easier to tackle this with you if I spoke with you.
That is a question that is commonly asked. The factory alarm system is integrated into the car and cant be bypassed.
For the starter not to engage or get power, did you check power to the relays i mentioned?
I am currently away from my computer. I will be home in about an hour or so.
Did you jump the pins as I suggested to see if the starter engaged
You remove the relay and with a piece of wire jump pins 6 to 7 as i suggested to you earlier
Ok.. I will be online tomorrow around 7 pm Est and be online till 10 or 11pm.
If pin 6 does not have power. That comes straight from the ignition switch. So either you need a ignition switch, or you have a after market alarm tapped into that wire keeping power from getting to that relay which would allow power to get to the starter for it to operate.
If you have any more questions on this, please feel free to ask.
If not, and you're satisfied with my help, please Rate me. That is how I get credit for my work.
I hope I have provided you with Excellent Service.
This would be so much easier if we can speak.
You still don't have power at pin 6 with the key in the crank position at the inhibitor relay?
You need to check power directly out of the ignition switch. If you have power directly out of the ignition switch, you must have a after market alarm interrupting the power to the relay or you have a broken wire.
That is the only thing that is making sense to me. Check power at the Black wire with the White Stripe at the ignition switch. If you have power coming out, then you have something interrupting it from getting to the relay. Either a broken wire or a after market alarm.
Remember, we are checking to see if the Black wire with the white stripe has power when the key is turned to the Crank Position. Meaning where you would try to start the car.
Wait.. All this time I was thinking the starter was not engaging. Is the engine turning over and not starting?
Jesus.. This whole time I thought the starter was not engaging to turn the engine over. If the engine is turning over, then you have power at pin 6 at the relay.
When you turn your ignition key to the ON position, is the security light ON Solid?
Now we need to check the car for codes. Do you have a way to do this?
Also we will need to do a fuel pressure test and check for spark and injector pulse.
Are you able to check for spark and fuel and injector pulse?
if you popped out a spark plug see if it's wet with fuel also
Remove a fuel line by the fuel filter, and turn the engine over and see if fuel is coming out. Make sure you take the hose that you remove and plug it in a glass bottle for the fuel to go into if fuel comes out.
Did you try pulling the hose off at the pump to see if you have fuel
Then the pump you brought is defective if you hear it operating and it's not pumping any fuel!
If you are buying them from your local auto parts store, that is most likely why. Get the part from the dealer. After market parts are junk and will having you chasing your tail and have you spending more moneynon parts you don't need.
If the pump operates, but doesnt pump fuel. You need a pump!
If the alarm is active it kills injector pulse, not the fuel pump. So if the pump is operating and not pumping fuel, the issue is the fuel pump!
