Need help getting my Q started

[Blipman]

Hi guys,

I've just imported an '89 HG50 Q45 from Japan and I'm having trouble getting it started. It WAS starting ok before, when it arrived it ran for about 10 minutes (idling) then ran out of petrol. I put about 5L in and it started again, and I drove it about a km up and down the road. 3 days later I moved the car in my driveway, worked on it (just cleaning the interior and putting interior trim into the trunk) and then tried to start it about 2 hours later, it would crank but never fire. I put another 5L of petrol in but still no luck, I pulled off one of the fuel lines and even cranking it there's nothing coming out, so there's a fuel pump issue I believe.

And that's about as far as I've managed to get. I've checked all engine bay fuses and one was blown, a 30amp fuse (the green one in this picture), my fusebox is not labelled so I have no idea what it is, the fuel pump still doesn't work, the only thing which didn't work previously was the airbag suspension (NOT Active suspension) so that may be what this was for?

Does anyone know what this fuse is, and are there any others which could be fuel pump related? The interior fuse box is labelled in Japanese so I have no idea if there are any I should check in there, I'm having this translated now.... are any of those possible culprits?

So, can anyone offer any advice on what to try? It has occured to me that the pump might have overheated when it ran out of fuel, but I have started the car several times and driven it since, so I'm not sure. If the pump is dead are there any other Nissan pumps which are easily interchangeable? I don't really relish the idea of trying to find a Q45 pump in Australia when I'm not even sure if it will solve the problem.

The fuel pump fuse is inside the vehicle right above the parking brake release. Its 15a, I believe, and usually blue. It does sound like you have a dead fuel pump and/or fuel pump controller.

The fuel pump controller has been known to go bad. There is a quick fix, to get it working temporarily. I don't know the thread, but do an exhaustive search on fuel pump and FPC.

The fuel pump is about $250 US and the controller is above $300 US.

I recognize that yellow overspray. Is this the VIP Q you got in a Japan auction?

Here is the fuse order down the center from back to front of the fuse box in the front of my 1994 Q:

Engine Control 10AFog Lamp 15 ARoom Lamp 10ATail Lamp 10AALT(s) 10ABlankHazard Lamp 10AHorn 15AHead Lamp LH 15AHead Lamp RH 15A

Here is the big ones to the Left:

Here are the ones to the right:

TEL (10A), TCS (20A), ANTI SKID (20A)Cond Fan (30A)INJECTOR (25A)ENG CONT (25A)TCS (30A)IGN SW (30A)blankMAIN (75A)

Then to the far right are the 2 main fuses:

100A, 120A

It may not be the same, but I though it might help.

Thanks for the info Jeff, I got some of the interior fusebox translated as well (see the other thread) so I've now got a good handle on all of the fuses, although the green 30A fuse that was blown on mine you're telling me should be a 15A for the fog lights... interesting.

My plan of attack is to go over fuses, then apply power to the pump, see if it makes a noise. If not then the pump is dead and I have to find another, which won't be easy... can you remove it with the tank in position or does the tank have to be moved?

If the pump is fine and it's not getting power then it gets interesting....

Yep that's my VIP overspray beast, I'll have pics soon.

Yes, look for Tangalora's definitive post.

But don't put a new pump in a less than perfect tank, or without replacing rubber in fuel lines or blowing out metal lines. New fuel filter also.

Plenty of posts on fuel pump pressures required under all three stages.
