Fault code 143

[Glen]

I give up i have no idea whats wrong with this sr20 micra!

 

[frank]

did you try the non nats ecu glen ?

 

[Glen]

I cant find the pinout for the primera p10 ecu

 

[frank]

there,s loads of fsm,s on the nissan forums mate, its the micra ones that are only in russian or italian

 

[Glen]

Yeah but the ones i find dont match my connector that i have for the p10.

colours, or pinouts ?

 

[MarkTracey]

Ill have a look on autodata at my work and ill give you a text if i find anything useful mate

 

[Stani1029]

It's a scrapper just like mine now haha!

 

[Glen]

Fron what i can see i can bridge the fuel pump relay and plug the ecu in and it should run. If this works can i just remove sll other nats gubbins or would i need to bridge the connections.

 

[frank]

the nats cuts the injector signals tho eh glen, cant you fit a non nats loom ?

 

[Glen]

But does it cut them in the ecu. So if i fit non nats ecu then would that not solve this

 

[frank]

But does it cut them in the ecu. So if i fit non nats ecu then would that not solve this

yes it stops the ecu from sending injector signals (i,ve had to run my red car on a 5th injector to test my engines) , and the nats pinout is different eh, so best fit a non nats loom

 

[Glen]

Its getting a non nats loom that isnt easy

 

[Glen]

Would a fuel pump cause any of these issue's

 

[frank]

i doubt if you would get a 14-3 code glen, mine gave 14-2 14-3 and 14-5 but runs ok on the 5th injector (hence the pump is fine, but the 4 injectors are cut)

 

[Glen]

How do you run the 5th injector

 

[frank]

How do you run the 5th injector

a button on the gearknob glen i was only testing my recent rebuilds out

 

[Glen]

Would the crank pos sensor cause this fault?

 

[frank]

if the injectors have a live feed and some pressure, but it only runs if primed with fuel down the t/b glen ?
then it can only be the -12v negative signals from the ecu to the injectors at fault eh = nats

 

[Glen]

Its just the fact it doesnt start now but if i put fuel in the throttle bodie it does

 

[frank]

Its just the fact it doesnt start now but if i put fuel in the throttle bodie it does

and the injectors are showing 12v (on my multimeter ) when the ign is on glen ? and the fuel squirts if you pull the hose off ?

 

[Glen]

Yea 12v and plenty fuel

 

[Glen]

P10 Ecu code 143


GTIR Code



Not sure what code the gtir ecu is throwing out wether its a 11 or 21 code?

 

[Glen]

Whats fault code 11 or 21 and how are they solved?

 

[frank]

CAS, they,re on that fusion link you posted eh glen
