Hey all,

Ive been having some problems with my GTR and Ive tried everything on the forums relating to the problem and its still occuring. I cant trust the car enough to drive it down the road in fear of having to get it toed home.

The problem consists of mainly No power, Cutting out, Not starting after cutting out.

The car has been at my Auto Elec for the last week and he has tested my Ignition module and CAS, (bench tested) also done a fuel pressure test on my fuel pump. All came back peachy. I also got my AFMs reconditioned a week ago.

My Auto Elec basically said to me he needs the car in the shop when it is completely dead and wont start again. He told me its not worth buying parts that 'could' cause the problem, for the obvious reason being money. I cant wait for that though as i depend on a car to get to work etc.

If anyone has had this problem, something similar or even knows of some1 that has had this problem please throw me a bone. im at the end of my ropes..... if i cant fix it ill be buying a commodore ..... maybe not lol

cheers joel.

i was reading through your other thread today, seems you have gone over everything :s do you have access to a stocky 32 gtr computer to test?

[joeleo87]

im currently talkin to some1 about buying 1 to test.

its all i have left

^^^ good point. my car cut out on me ages ago, it completely shut down on the freeway. turned out to be the ecu, which i replaced with a power fc.

[rhys5169]

could it be as simple as a bad batch of fuel??? probly isnt but just seems youve covered everything! i feel for ya mate

[joeleo87]

i wish it was as simple as a batch of fuel

the problem has happened over the last month or so tho.

[love my 32]

I had this problem with my 32 gtst, while driving it would cut in and out of boost, turn it self off. Had 3 different mechanics and auto elecs on it and still couldn't solve it. changed ecu, all sensors, fuel pump.

Then i took it for a drive with michael at turbo tune and he fiddled around with the tps sensor and it ended up being a faulty tps. We got one from jap land took ages put fixed the problem. I'd give that a go.

Im sure youve checked it but while its running, move all different parts of the loom, especially near teh cas, ignitor pack etc...a bit of vibration can pull wires in the wrong direction if they have a bad connection...so while its running move around the engine bay and lightly move the loom around...could find the problem.

[joeleo87]

thats an idea... im not sure where it is on the GTR tho? any1?

[Vija]

Hi, had a similar problem when I bought my R32 GTR. Both AFMs and coils were causing the problem. Opened up each AFM and resoldered the 4 connections, then used silicone on each coil pack to make sure they weren't arcing. Oh yeah, get copper spark plugs and gap them to 0.8.

The AFMs were causing it to run like absolute crap with no power, cutting out, etc. The coils/plugs were just a slight misfire.

Cheers,

Matt

where what is mate?

[joeleo87]

Where the TPS sensor is?

cheers matt for the thought, ive had both AFMs reconditioned and my Auto Elec checked the coil packs

im hoping its not a new ECU but if it is it will be a great weight off my mind lol

[Ryanrb25]

opposite side of the throttle cable on the throttle body mate.

[joeleo87]

can u clean the TPS? does that improve the idle?

cheers

[Sinful]

Joel,

Put this thread in the Forced Induction section!! Might help

You have checked all the normal stuff that usually cause's this, so I would be leaning towards the ECU aswell..

[Damo_R34]

Joel just get a power fc

[Katatonic]

I sent you a PM.

[joeleo87]

Yeh ive put a similar thread on the forums but not really getting many responses. although that was a while ago. i may repost with more details

Damo u just watch out for that old lady lol. got HC yet?

cheers richard

[Ryanrb25]

borrow a Power FC off someone and do a sensor check, maybe that will tell you something....just an idea.
