I am working on a 2002 Nissan Xterra 3.3L 6 cyl.   Kept cutting off.  Replaced a bad fuel  pump.  Ran for about 2 weeks. Starting cutting off again.   Have to wait 2-5 mins before you can start again.  Replaced fuel pump again, fuel filter and fuel relay.  Continues to cut off after only a few minutes, and wait again.  I am thinking computer (which there are 2 as you know). Can get expensive to customer. Any thoughts

ek het ‘n nissan navara 2.5dci 2006 model. teen 140km/h in 6de rat teen ‘n opdraande voel dit asof die bakkie wil uitsny as gevolg van ‘n tekort aan brandstof toevoer. ek het reeds die quantity valve vervang asook nuwe dieselfilters ingesit en die air intake sensor skoon gemaak en die bakkie doen nog dieselfde.

kan iemand asseblief vir my sê wat moontlik die probleem kan wees?

I have a Nissan Altima 2000 which i bought a couple of months back with 122500 miles on it.
Some days ago there was no Antifreeze /coolant in the car ( i had checked the Coolant box and the Radiator both were empty or there was hardly any coolant) and hence

it will not leak or the coolant will not come out.

Recently i filled my Car Antifreeze box with Coolant fluid Prestone® 50/50 Antifreeze/Coolant and also filled some coolant in the Radiator directly.
2 days back i got my oil changed at Firestone and i was alarmed that the coolant is leeking from radiator along the Seams 431459 RADIATOR
(sides or radiator tap) actually there were few green spots.

so my question is “yesterday i went out and drove around 20 odd miles and there were vapours coming out from radiator as the antifreeze was spilled over the Engine and

SEAM’s of radiator, antifreeze was dark Green in color when i opened the Radiator cap which was very light in color when i initially filled it.

so is it normal or i need to do some thing.”

According to firestone i need to change my
