20v Starting Issues

[mad.matt]

Hi all,

I've recently had big issues with my AE86 20V swap not starting recently. Parked up overnight and just would not start in the morning.

Running a lost spark ignition system with COP - Yaris coils.

Giving intermittent pulse on spark timing. 1 spark every revolution at the wrong line.
Firing from Intake trumpets.

We have done:
1. Pulled fuel pump and cranked to clear fuel. No change, not running.
2. Checked spark strength, fine. No change.
3. Checked timing, off by 20'. Fixed, no change.
4. Changed ECU, no change.
5. Compression test, no major issues.

Anything else I should check?

Cheers,
Matt
