Sir ive already check for codes thru computer consult they cannot find the answer or there is no code one of the mechanic told me that when I turn the ignition on he can hear the fuel pump pumping so definately the pump is working he told me maybe the alarm system is malfunctioning so he told me to bring it to the electrical shop so they can disable the alarm and observe it, and the second suspected cause is the ignition relay he said that when thw relay is hot that shuts of the engine then when you leave it for 15mis it cools down then starts again my question sir is is that true is there a posibility that this rwo are the culprit. Hope you can help me with thus thanks and more power

Just becaue the fuelpump is working dosnt' mean it gives enough pressure when hot to run the car that is why I said check fuel pressure with gauge. If it's ok fine but make sure. If this si the same as a maxima which I think it is here in u.S there is an eccs relay in fuse box underhood it supplies crank sensor and pcm. However relays normally work or they don't. But because it supplies the crank sensor have the resistance checked in crank sensor if it's to high it 's getting hot and not working or cutting off. They will do that and not set a code. It should be 440-570 ohms at 77 degrees so if temp is higher or lower compensate for it. If it is in the 800-900 ohm range and around 77 degrees F then just replace it. It also could be anti theft but I don't 'think so. It can also be a connection problem 77F is 25C
