Title: problem with my s13rb25
Post by: az240 on September 05, 2005, 03:24:08 PM
hi eveyone, my name is chris, and I l ive in phx az usa, and I have had my s13rb25 for about a year now. I have had this problem when the car gets up to normal operating temp. and if i were to turn the car off, it wont start. car runs great even when hot, just when I turn her off, she just wont start until its completely cold (an hour or 2). Ive changed plugs, turned down my fuel (FPR was around 38-39psi), but still nothing. Is there anything else I can do? might i need to change the temp sensor? do they go bad? it turns over I didnt notice if its fast or slow, but I do get both spark and fuel... it does seem like it hesitates while at idle..but very minor..I have checked for boost leaks, and cant seem to find any....if I had a bad sensor, wouldnt I have a check engine light? any help would be greatly appreciated....love my rb!!

Series 1 or Series 2?  If series one, sounds like it might be a bad ignitor.  Not firing good when hot.  I think one from Z32 will swap with slight modification.  Dont take my word for it, just my guess without seeing it.  Does it try to fire at all, or just spin over?

On the forums, a dude had a similar problem, it turned out to be the igniton
module on the back of the motor. His cars engine would cut out while driving
for about 10 minutes or so and wasn't able to start the car for about I
gather was another 10 minutes.

I was told that they get moisture inside the casing and they play up.

I was told that you can get the ignition module reconditioned. I gather
like you can with a AFM, when it has a solder problem.

I gather you can test the ignition module on the back of the motor, via
using an oscillioscope.

The other sensors I found to cause idling problems are a faulty TPS
(Throttle Position Sensor and is located on the throttle body)
and faulty O2 sensor.

Missing can also be caused by leaking coils (grey marks on the side
of the coils, under/near the mounting braket are a sign of them leaking).
