Nissan Platina does not start

Hello, how are you like and greet everyone, I tell you that I have a Nissan Platina 2005 standard with air, the car was perfect but little by little to state presenting a failure in the mornings like 7 am (the climate is fresh) the car took it to start, at the beginning that the pump needed to give it time to send gasoline, but we In the afternoon when the heat is to everything, and it does the same, it takes a long time to start, so that they have an idea I go about 3 or 4 times from 40 to 50 sec, and then it starts without a problem and does not fail more until the next day, it does not matter if I use it only a few minutes or if I use it all day, the fault has been increasing, that is before that fault of time, but now it is almost every day. And most coincides that it is a fiddle sensor of the crankshaft or something, but I would like to know if someone has happened to someone and as they have solved it, it should be clarified that outside that the car is perfect and once it turns on it does not fail anything at all, taking advantage of a few years ago I bought an EML scan with a USB port for my laptop, will it be connected to this plate? Greetings again and thanks your help.

The gasoline pump changed

The problem is that the car only in the morning at the first start, that is the failure once it starts it no longer fails at all, the fault does not appear when doing any service or repair, and the car has been done its services in a normal way, so I discard that it is the pump because if that were to fail intermittently, either when it is cold, etc.

Generally, the problems of the cold games are due to the temperature sensor, you could check its proper functioning, the other thing that can happen is that the air filter is obstructed is to say a basic tuning, and the other that the injection ramp is downloaded, but the temperature sensor is the main culprit, one that checked the basic tuning.

Hello, how are you? I work in my city in a workshop where various failures are treated.
It is very likely that it is the crankshaft position sensor, but this tends to turn on the car to be delayed, to such an extent that it no longer turns on. I would recommend if you have some mechanics skill that you will release the CKP sensor (Crackshaft Position Sensor) located in the case of the gearbox under where the temperature sensor is, guide it by it, stop an avionncito, it is more so they call some mechanics, after removing it, try that someone will start your car to make the engine Piege of sandpaper so that it somehow remove oxide or dirty that can be found in the teeth in the inertia steering wheel that serve the info sensor for the ECU. Or while the rock engine turns carburetors, or do the two things ... I have done it in several models of those cars, here in Colombia it is marketed as Renault Symbol or the Citius in public service version. There could be discard that sensor ..

Another suspect could be the fuel pressure regulator that is located in the fuel module within the fuel tank.

Other thing that I advise you to check is some fissure of some plastic element (hose) that drives the fuel from the pump outlet to the pipe, can be broken or chopped, that could also cause the fail that you comment ...

Bbueno I hope it serves you, if you need another thing I will gladly help you, let me know how it went .... Good ???
