SR20DET intermittently failing to start!

[CryScott]

Looking for some insight from you guys. I've got a 95 Zenki with a Blacktop SR20DET. For the past 2 weeks ive been having trouble with getting it to start. Intermittently the car will just click when the key is turned to the on position. I have replaced the starter for a brand new ISIS unit, replaced the fuses and also replaced the ground for the starter with a brand new line.

Some situations that can often cause the car to start, after the key fails to start it first time.

- Disconnecting the negative terminal and reconnecting it sometimes works.
- Wiggling the starter ground sometimes works.
- Pushing the car and then popping the clutch, then stopping and using the key worked (mysteriously)
- Wiggling the fusebox sometimes works.
- Waiting for 5 minutes sometimes works.

Basically, I'm all out of ideas, every time I think i've got it fixed, the car will leave me stranded.

Picture of the car for attention:



Thanks in advance!

I had a similar problem when I first got mine. Either Norris Designs or my local Main Dealer traced it to a dry solder joint that was breaking connection when warm

How did they diagnose it? I'm about to replace the ignition switch.
I'm thinking at this stage i'm going to go through the whole motor and just replace the whole ignition circuit.
