Pud's patrol HELP

so Nissan aren't a diesel specialist? :-)

Reminds me of the time I had the alternator replaced on my rangie by a local mobile auto electrician. I cam home to find a new alternator installed, but the charge light would come on with the engine running but not with it stopped and the key on. I rang him and said i think you have the wires hooked up the wrong way. No way he said, it will be a blown fuse, those range Rovers have fuses everywhere.

So I asked him to come around again and look at it. In the meantime, I got the wiring diagram out, showed him no fuses, and proved it was wired up wrong. I said, so now it will be burned out (diode), so best you replace it FOC. His reply, "the wiring is pretty complicated, I will get a mate to look at it, he is good at this."

I said, "you're a flamin' auto electrician you are supposed to be good at this"

Still can't believe it happened.

Take it back to the dealer, leave it and don't pick it up until it has been fixed. Ring them every day and pester them about it. Don't except the vehicle until you are absolutely certain they have done the work. Check the starting yourself, speak to the foreman and the mechanic who worked on it. Get copies of all the invoices for any parts they replace, for future reference. If after a week it has not been fixed, ring the PR department in head office, start annoying them too.

I would have the fault codes scanned because it sounds like a faulty coolant temperature sensor.
If it is reading cold all the time it will start easy when cold but be hard to start when hot. If it is coolant sensor it should also run rough or be over fueled when hot but not necessarily. These electronic engines give weird symptoms.
I will have a look tomorrow at work in my electronic fault codes book and see what code is for the coolant sensor and then let you know.

G'day Pud,
Do you have access to the vehicle? If so, try pouring some cold water over the injector pump when it's hot and bothered and doesn't want to start, see if starts easier immediately after the cold water treatment.
The reason I say this is because I have the 2.8lt which is giving me the same problem, easy start when cold, near impossible when hot, was stuck at a shopping centre and coudn't start the damn thing, while I was sitting there fuming I figured if it starts when cold, let's cool the pump down, started almost straight away, have been doing this for a week now whilst waiting to get in the mechanic's.
Everyone says straight away that it's the internals of the injector pump wearing into the housing, which is a common problem with the 2.8's, but I've already had this problem addressed and fixed 12 months ago' and besides, this problem happened within a dozen starts over a couple of days, I figure it takes longer for a slight wearing problem to give a problem than this.
I think it's a sensor of some sort playing up, am hoping the mechanic finds something as he tends to agree with me.
Would be interested in knowing if yours has the same symptoms.
Will let you know if we get to the bottom of my problem.

I hope this thread gets to the bottom of this. I went through similar events with a motor rebuild then the dealer insisted that the fuel pump needed work as it had trouble starting hot. It did this a bit before the rebuild but the dealer said it wasn't running right and wouldn't start hot. $700.00 later it was solved for a few months, now is exactly the same as it was before the rebuild. Usually turning the key right off and waiting 10 seconds or so lets it start, sometimes requiring some throttle application (not supposed to do that though)

I'm wondering if the disconnect the battery for a while th reset the computer may help this???

PS will probably be fitting the lpg fumigation to the mighty 2.8 during the year, and will submit a report here when its done. I havent found anyone who has done one yet....

This may be a silly reply - but are you allowing time for the glow-plug (presumably there is one) to heat up before attempting to start? If not, then cranking drops the volatge to that plug and starting is delayed.

G'day Pud,
Got mine back today, he got the computer checked for all the codes and nothing came up, so he ended up fitting the second hand pump I'd gotten, the only thing he didn't swap over was a sensor in the side of the pump ( these pumps have three sensors, one in the side, one in the back and another underneath I think it was. ) as the connector had been broken by the wrecker guys (how unusual). It now starts as it should when cold or hot, problem solvered.
The mech initially thought it might have been the sensor in the side, but seeing as it has the same sensor (that was the broken one on the wrecker pump) it obviously wasn't that.
We still think it's a sensor, but not sure which of the other two it is, I left the pump with him to play with, hopefully he can solve the problem.
I also spoke with Tony Motson about it, he seems to think the problem is inside the pump somewhere, but he couldn't figure out how pouring cold water over the pump could solve an internal problem, which is the reason why I think it's a sensor.
We may never find the problem, though I will let you know if he finds anything when he has a play with the pump I left him.
Interesting thing I found out after all this is that I'm definately using the correct mechanic, was quoted $400 by the mob in hamilton to R&R the pump, and 5hrs by Motson's, which equates to a hefty bill at their rates, final cost at Paul Geary's was 2.50 hrs at $167.
Tells me how much some of the others are willing to rip us.

Hi everyone who has been helpful, it's still at the dealers. Pud found a place in Sydney today while he was driving around waiting for a return load, they said they wouldn't do a rebuild without doing the fuel pump as they couldn't guarantee it. Makes sense after reading and listening to everyone we have spoken to. They said to take the pump in when Nissan gets it off and they will test the injectors etc. Why Nissan can't do this is beyond me, but hey, just being the owners of a heap of cr$p what would we know. He also spoke to the guys in the workshop at the depo and they all reckoned it was the fuel pump as well.
Sorry he's not here to reply to you all, he's catching some much needed z'sssss. Done a lot of hours this week.
Thank's guy's
