03 Pulsar won't keep running

[cosmo358]

Hi everyone Cosmo358 here from Maryborough Qld. I have an issue with my 2003 Pulsar N16 sedan. I bought the car for my daughter as a learner car. It's done 188204kms and is an auto. The issue is the car will start and run for about 5 seconds then stops. The fuel pump is working. I had the immobilizer checked and it's working fine. I have replaced crank angle sensor, cam shaft sensor. Previous owner had replaced a lot of parts as there was a box full of parts. He told me that he had had the same issue but as he couldn't resolve the issue which is why the box was full of parts. He sold the car. I was aware that there was an issue. My question is, does the BCM control the fuel pump as it seems that that maybe the reason it wont run. It,s the only thing that was not replaced. Also, where is the eccs module located, or is it combined with the ecu? I'm really stumped so any advice would be greatly appreciated. Many thanks Cosmo

The ECCS and ECM are the same thing, and on an '03 the ECM should control the fuel pump. There's no Nissan I know about where the BCM controls anything except cranking and security. The quick test to incriminate or exculpate the fuel system is to spray something combustible like Brakleen or Gumout down the barrel past the air filter. If that keeps it running then the problem is fuel starvation, if it doesn't then you're barking up the wrong tree.
