Nissan primastar trouble

One shot on kill

Hi guys

Hope alls well

My Nissan wouldnt star twice today I had to toe it once now I think the immobiliser is acting up because the light is flashing fast when I try start it I it has happened before and I use to think it was a deisal problem but now with the light I'm all over the place. I try both keys but to no avail.

ANC yes I have spent a right few pound getting it put on diagnostics to see what up but that was also a waste of money

Dose anyone have any ideas
PLEASE
Thanks

if you take out your dash clock and look down to the right you will see a black box with a white label marked uch,remove the plug and see if its corroded as i've seen this problem a few times with non starters (immobilised) renault,nissan and opel vans.this unit recieves a signal from your key and then in turn sends signal to your ECM.
If this does turn out to be your problem you can replace it with a used S/H unit but it will need to be programmed.
could be wrong but worth a look.:)

One shot on kill

I went out this morning and the van started up after e few turns then it stopped again I changed the battery in the key and it's started every time since could this have been the problem

No !
Battery in the key will have absolutely no bearing on your fault.
As already posted, uch/plug is common fault
