Engine turns over but doesn’t start on a Yaris VVTi - Toyota Yaris Forums

Thanks Bluevitz-rs
I put new plugs but no improvement.
I have been pulling the EFI fuse recently before the compression test. I didn't at first. I have always held the throttle open for the test.

I have taken the rocker / valve cover off now.
First impressions are the timing chain is fairly slack but I doubt it's enough for it to jump off the cogs. It is a VVTi so I'm not sure how to check the correct chain slackness?
There is quite a lot of water under the rocker cover. The car has been outside unused in the cold for weeks.
Some photos of it:
