R33 Dies When Hot!

[Brady_033]

Hi all, I am having trouble with my S2 R33 GTST, have had a look around the forums but so far nothing has really helped.

The problem is when the car gets warm it just dies (can crank it over but wont fire) and wont start again until cold.

When the car is cold it starts first turn of the key and will drive around and wont miss a beat until its warm and then wont start again.. The problem has been occuring for a little while now but thought it was fixed after unplugging the ECU (Nistune) it didnt happen for about 150k's (the car doesn't get driven very often)

Have swapped the cas and afm (Z32) for known working units and it didn't make a difference, plugs look alright and the Splitfire coilpacks are only around 8 months old also unplugging the coolant temp sensor doesn't do a thing.. Car also drinks a fair amount of fuel round about 300 Kilometers to a tank on 98.

Could this be an issue with the tune? any help would be greatly appreciated cheers.

That's weird. I had my $ on the cas

what's your temp gauge showing?

Will it start hot if you give it a bit of throttle?

Does it crank slow ? Like a flat battery ? Could be your starter motor solenoid sticking/faulty, a friend had an old hilux that would start fine when cold but once up to running temperature, if he turned it off he wouldn't be able to start it for a few hours till engine was cool again.

Fuel pump getting hot? Check fuel pressure when its hot..

CAS was changed, hmmm, how is the earth connection at the chassis and on the block, I had trouble with my old one, as it heated up it would lose contact.

Hey guys sorry for the delayed reply..

Answers to previous comments..

defari- temp gauge says abit under half when it dies

blind_elk - Wont start if i give it any throttle just floods it and runs like shit when it eventually fires haha..

Lrs94- Nah doesn't crank like a flat battery cranks like normal

Kane_R32 - Fuel pressure is good after car shuts off

mlr- Where abouts are connections on chassis and block?

UPDATE- Turns out the cas i tried turned out to be an RB20DET one plug was the same but apparently the timing is different? And i ran the car the other day and when it got to temperature it didn't shut down and even took it around the block and let it sit at home idling and didn't die?
