Urrgent R33 Cuts Out When Warm

[KnightRiderR33]

Hey guys so last week friday my r33 gtst decided it would break down on me. Thought it was a fuel pump so i organised a new one through work and gave it to my mechanic. He thought it was a fuel pump issue aswell the car would cut out randomly.

anyway i got it back today and all was well untill the car reached normal opperating temp then she woul cut out and wont start up. if you leave it for 15 mins or longer she will start up again. i took a quick look at the lines and they all look good but when i checked out my piping from the intercooler i noticed that for some reason the intercooler piping closest to the plenum had been rubbing up agianst the chassis and caused a nasty cut in the pipe which i thought could be the problem so i managed to get the pipe off and use a bit of quick steel + tape to patch it up to atleast get me home. i thought it worked but again it broke down has anyone come across this issue????

i had a the same problem turned out to be the AFM

i also had a similar problem although i only had a major missfire not quite stalling when the car got to operating temperature, it turned out that 4 of the 6 coil packs had cracks and as the engine warmed up the cracks expanded causing the sparks to jump outside the coil. might be worth a look.

Borrow an AFM to try

[ZacZerbst]

generally if the afm is faulty the car wont run at all, cold or hot. but like greeko said the same thing happened to him and it turned out to be the afm. so if you have access to an afm its worth a try. let us know how it goes

[Stevoss]

yes cas they heated up causing the insulation to break down enough to cause the car to stall and wont start until it had cooled down.

have you got a spark plug gap tester tool you can use?

like this so you can actually see if you are getting spark

use a test light pull 1 of the clips off the injectors and test across the pins on the plug to make sure you are getting a injector pulse with the car cranking.

Check coil packs
