Skyline ER34 Warm Start problem

Recently I had this very annoying experience whereby the car simply refuses to start when the engine is warm. First I had this experience about a month a go when I drove it to the nearest Car wash. The distance was about 3km. Then gradually it happened during stop for re-fuelling. At times it with start after 3 or 4 crank and at times it takes solid 10 min rest.
To describe further on the symptom....it happens when I drive for a very short distance and requires stop and start the car. It would take multiple attempts tp get the car to start.

Brought the to local mechanic and he diagnosed it with a faulty CAS. 

One the CAS replaced it went back to business as ususal.

Crank Angle Sensor (CAS). 

The actual issue occured between Jan to Mar 2012 and was resolved within the same month.

Tein Super street suspension

My ride has been with me for the past 7 years. As such, I strongly believe that every ride will have it's own so called maintenance period. We can't skip this for sure, however we always can reduce the probability. that is depends on the each owner. Some will go an extra mile by replacing wear and tear parts according to service manual and some would wait for some kind of symptom and there are some wait till it breaks. However I am not focusing on any category of people here.
I am the type whom will wait till there is a some kind of symptom. Having said so, there are times I had been pushing the car till it breaks down completely. Recently a friend of mine has offered Tein super street with EDFC for a reasonable price. Since the offer was good and I have never used EDFC before and thus I quickly accepted the offer. Installed on my ride, done some adjustment for the EDFC, well I am not sure it is at the optimum settings.
