Hi I have a 1997 GQ Patrol 2.8 Turbo deisel.... The problem I am have is one morning I started the beast and the techo went from left to right 3 times then died also the light for the glow plugs does not come on anymore nor does it make that click over noise if ya know what i mean.. I checked the fuse box in the drivers side kick panel and checked the control unit thats located just below the fuse box i thinks its called the ecu and the patrol runs alittle bit hotter but not much. I have read all the ecu problems on this forum but with no resolve. I have phoned nissan and they want $1,400 for the ecu and wreckers want $550. I am also wondering it is the ecu... I also can take pics of the board of the ecu if anyone can tell by a pic if its unfixable..

GQ 2.8 turbo diesel has a mechanical injector pump - it's not computer controlled. The ECU you are looking at may be the glow control unit. I would be getting either an auto electrician or a diesel specialist to check the glow plug operation before you go spending big dollars on something that may not be faulty.

It could be that you glow system is working normally (is the engine hard to start when cold?) and that it is just the dash indicator light that is not working - you may have a faulty instrument cluster.

The control unit may also be turbo timer unit if fitted with turbo.

thanks for the info..... It happened all at once tacho spiked left to right and glow plug indicator stopped working along with the glow plug click noise when turning the ignition on. so from that day on every morning when starting the car it kicks over about 8 times before starting when it use to start first go every go no problem.

oooooh sh!t also forgot to say in the post the horn does not work anymore either and the other thing is my front window seal is leaking i found this out after the big rain sydney received last week and found my drivers side carpet all wet the water looked like it leaked down the side where the fose box and glow box is... i think i may be up shit creek but thanks to all for any info. been trying to find the book on my car found it at nissan but they want like $600 it may be a good investment because i enjoy working on my car.

So Nissan was gonna sell Sean an ECU he doesn't need for $1400?? F@$% I hate dealers. Scum.

yep first he said he could not find it on his computer for my model car then he said found it and this was also him having my vin number to check so silly me is like yep he must know what he is talking about. To be honest i get better advice on this forum

That ECU may just be the glow control unit, in which case it is a necessary though somewhat over priced component.

Going by Sean's description of hard starting it sounds like there is a fault in the glow circuit somewhere, but I would be getting it checked out to confirm which part is at fault before just buying expensive parts.

Check all the earth points you can find to make sure they have a clean contact with the body/chassis.
