GU Patrol help

Diesels do the same thing but it is a blocked filter located in the injector pump. I would be checking the fuel flow especially in line filters.

Not sure where the fuel filter is located, but my bet is that the filter(s) is blocked. Many moons ago, I was approached by a bloke who had a VW fastback which had the same symptoms. It would go for 20 km, then stop dead. Wait a minute and away it would go again for another 20 km. I guessed fuel filter and we went for a drive in - 5 Deg C temps with me holding a pressure gauge out the passenger window, and petrol dripping all over my hand. Sure enough, after about 15 km, the gauge started to drop and at 20 km the engine stopped. Wait a few minutes, start up and drive home and it did it again.

His problem was the fuel filter. He had been visiting his grandkids and had parked next to their sand pit. There was this nice little door and a cap under it, whuch they unscrewed and shovelled an unnown amount of sand into it. He had to have his fuel tank removed and cleaned out, and a new filter. All OK after that.

The hot smell would be the engine running too lean, and the exhaust manifold probably glowing red hot. I would replace your fuel filter and hopefully fix the problem.

On my troopy there was a crossover switch from 1 tank to the other. This had a piece of paint from a jerry can blocking it so it was starving. Start at the tank, follow the lines and replace every filter AFTER you have drained some fuel from the tank into say an ice cream container to check the fuel for contaminates.

good luck.

Just another thought....... along the same lines (fuel flow issues).

If you stall again, as quick as you can get out of the car & remove the fuel filler cap. If there is a noticeable vacuum as you remove it you may have a blocked or partially blocked tank breather. If enough vacuum builds up it will stop the fuel flow.

G/Day Woodsy, I Wouldcheck the fuel pump, take the feed line off the filter and depending whether its electric or mechanical turn on ,or crank over and see what fuel comes out the line, but would only do this when it plays up!, other than that, what others are saying.


Cheers Axle.

Yeah fuel filter first as per others replies Woodsy, then listen to see that fuel pump is running.

Your engine fires so its unlikely to be the other main isue of intermittant crank angle sensor but its worth tugging the wires out of it when its running.

I could check and see if it has thrown any error codes if you like ?

If you do need to take it to a mechanic, after a download on it, get him to do a combined fuel pressure and flow test,
Cheers

Thank you all for your interest and replies

I removed the in-line fuel filter but problem still exists (and possibly getting worse)

I am tending towards a possible fuel pump problem

It is in for 190,000 service at Blackburn Nissan on Thursday so hope they can diagnose the fault.

Would still be interested of the name(s) of a good Nissan mechanic, Eastern suburbs.
