Help Please... R34 Gtt Issue

[Werkle]

Hi All,

I am new to this forum and would greatly appreciate any help.

The Story...

About 3 weeks ago I bought an R34 GTT 2 door... finally... car seemed in good nick, I have done bout 1500km's since and is my daily driver.

Mods:

POD filter

cat back exhaust.

(As purchased)

Now the issue I started having was the engine light, TCS, and slip lights intermittently coming on, they would come on and go away on restart. Sometimes I wouldn't see them for days. After a search around the forums I put it down to coil packs as the car would have a very slight miss occasionally when the lights where on but apart from that it ran fine minus a little power. Now to the issue at hand, a couple of days go I went to the shops and spent about half an hour there, once I came back to the car it didn't want to start. It would crank about 3 times as usual but it was like it just barely wouldn't start if that makes sense. It would almost fire but just not enough. I let it sit for about 20 mins after cranking it a few times and hey presto... started like normal(the engine,TCS and slip lights stayed on for the drive but car seemed to drive normally). Got home and turned it off and started it again within a minute or two and no problems 3 cranks and off she went no engine light nothing. let it sit fir an hour or so and again no problem starting and no lights on the dash, so I went for a drive for about 45 mins or so and stopped to get some food, again car started no problem. This morning on a cold start as per normal no issues, drove half way to work and stopped to get a coffee(normal routine) came out and again car won't fire. So I let it sit for about 20 minutes and it started like normal...hmmmm... drove to work(engine,TCS and slip lights on) car drove fine. Went into work and opened up, came back out and started the car (no more than 2 minutes since the car was turned off) no problems. so at lunch I started the car again and let it idle for about ten minutes again no issues. Turned the car off and about 2 minutes after tried to start it and it didn't want to start again.... car now stuck at work

I'm a noob to R34's so any help would be appreciated. The car is in Kensington VIC if anyone can help it would be great because I don't have a car at the moment and unfortunately I do need a car.

Thanks in advance to anyone that helps.

It sounds like either coilpacks or spark plugs.

First, replace all the spark plugs and see how you go with that. You can get a good set for about $70 off eBay, they go for about 100k or you can get the cheap ones at about a few dollars each. The cheap ones give good sparks but you would need to replace them every time you service the car. This is the cheap option.

Secondly, if problem doesn't go away, check the coil packs. While the car is running, disconnect the coil pack one at the time and listen to the engine sound. If you unplug 1st one and the engine is struggling even more then you know that that coil pack is ok. If you disconnect it and the engine remain running at the same struggling pace, then you know that this coil pack is gone.

It might be hard to explain to you here by typing. If you like, inbox me your number and I'll give you a call.

Other than this, it could be from the fuel pump.

One of my coil packs died before and I manage to get a genuine one for about $60.

Thanks for the info, the car decided to start and run for a bit today then died and started again for a bit and died again. When it runs it runs perfectly as in I can put a cup of coffee on the motor and wouldnt spill a drop (smooth). Luckely I managed through a friend of a friend to have it scanned today while it was running and it came up with low voltage, ignition and cas faults. I have a new battery for it comming tomorrow as the current battery doesnt want to charge. Will see if that changes anything.

In the mean time if anyone would have a cas sensor to suit the rb25det neo that I could borrow to see if that fixes the issue before buying one I would realy appreciate it as my funds are low at the moment and I need to get the car going asap.

I don't think this problem is caused by the battery. While the engine is running, the alternator should produce enough energy or electricity to run every single system. This is pretty logic, if the alternator can't produce enough electricity, even if you replace 10 more battery, they will die eventually.

Unless the main problem is your alternator.

Once fixed, don't forget to share the solution(s).

I agree with you but im a little desperate. Personally I think its the cas. I just need to get her going asap as public transport is not an option in my surcumstance due to my 2yr old needing to be dropped off at daycare before work and I only have a loan car for a short period. Shigh
