Customer reply replied 2 years ago
i did the top engine mount and the temp switch. it had been starting to run rough for a week and was getting worse. did those two things, then no start
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
You didn't do a Crank Sensor or anything?
Ask Your Own Nissan Question
Customer reply replied 2 years ago
no, but i did mess that up trying to figure this out. i thought i read that the crank sensor is for ecu diagnostics since the dist does both. btw, can i just solder the wires for the crank sensor to the leads on the sensor since i broke the connector?
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
Oh... You did some wiring work for the crank Sensor... What color are the wires to that crank sensor?
Ask Your Own Nissan Question
Customer reply replied 2 years ago
black with red stripe and brown
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
Ok... That is good. Some times the connector for the Crank Sensor can get mixed up with the coil connector to the distributor. That is where I was thinking your problem could be. I take it you disconnected the battery when you were working on the car?

Customer reply replied 2 years ago
yes, i have. dont have the security light on when the key is on tho
Customer reply replied 2 years ago
i hadent disconnected the battery before the no start issue
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
I am wondering if you may have a after market alarm on the car which may be active causing the problem. Other wise we need to look at the Ecm operation and may require a scanner to monitor sensors. Are you the original owner?
Ask Your Own Nissan Question
Customer reply replied 2 years ago
not original owner, but no alarm. i am thinking ecu also. i was not getting the 5v ref at the crank sensor
Customer reply replied 2 years ago
with key on
Customer reply replied 2 years ago
i will check for aftermarket alarm. usually under steering collumn
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
Yes, It's normally located under the drivers side dash. If you have one there, simply unplug the one big connector to the control unit and see if it starts.

nothing there
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
ok.. We could very well be looking at a Ecm issue. Do you have any codes right now?
Ask Your Own Nissan Question
Customer reply replied 2 years ago
let me check, but i had disconnected the battery for a while to charge it. will it throw a code for ecu just trying to crank it?
Customer reply replied 2 years ago
i do have a scan tool btw
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
If you had the battery disconnected longer than 10 mins, it would clear the codes. But I would simply scan it to see if it is throwing any type of hard codes right now... I am going to head home now. I will be back online in about a hour, or if you would like to accept the Additional service request, you can then call me or I call you if you like. Thanks Jay!

Customer reply replied 2 years ago
hour is fine. ty. i do have a camshaft pos sensor code, but this is my second new dist, since i took the first back
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
oh.. If you have a Cam Sensor code.. You are most likely dealing with a bad Distributor... If you have been getting the distributors from your local auto parts store, that could be why. After Market Electrical parts never work right. The Cam Sensor is build into the distributor and can certainly cause a no spark issue. I would get the distributor from the dealer. I know it's more money, but you won't be scratching your head and going nuts. That is what after Market parts do. If you want to talk more about this, I will be online in about an hour. If not, and your satisfied with my help, please Rating me. I hope I have provided you with Excellent Service. Thanks JAy!

also, i need to figure out this broken crank sensor connector problem
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
Yes you need to figure out that and work on the Distributor issue as well. Let me know if you have any more questions on this. Thanks Jay!

Customer reply replied 2 years ago
can i just solder the wires for the crank sensor straight to the pins on the sensor? this sensor is an ac generator?
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
The Crank Sensor is only a Reference. The Cam Sensor is the primary Signal. You want to maybe see if you can go to a salvage yard and snip off a connector if you can, so you can repair it the proper way. Thanks Jay!
