Code P1320, starts and stalls?

I have a Nissan Bluebird Sylphy 2002 G10 (QG18). It starts up fine but stalls after a minute, or whenever I changed the gear into D or R. It even stalls out after revving on the accelerator. I scanned the car, and it gave the code, P1320. I have replaced all the spark plugs and ignition coils. However, after checking the wiring with a test light with “Key On”, I have noticed that on cylinder 1 (out of 4 cylinders) the signal trigger from the ECM was not coming though. All cylinders have the 12v (... Battery voltage) and was well grounded. All other cylinders have signs of receiving signals from the ECM except cylinder 1.

It sounds like the crankshaft angle sensor is going out. I would look at the crankshaft sensor wave signal to see if it is disrupted.

The P1320 code on a 2002 Nissan Bluebird typically points to an Ignition Signal fault.

Here is the location of the sensor so you can check it out. I would look inside the sensor hole and spin the engine over by hand and use a flashlight to make sure the sensor reluctor teeth are all there as well.

Thanks for the reply, Ken L. I have already changed the Crankshaft sensor. Still same issue. What I assume now is the ECU is failing as no trigger signal was noticed for the 1st Cylinder. Any thoughts on this?

Yep, that would be the only thing left that can cause this kind of problem besides the wiring. Here is a guide to help you with the test and the engine/PCM wiring diagrams so you can see how the system works and which wires to test.
