So I used the RX-7 a very cold day where doors were frozen shut. Barely got them up. It started fine several times during the day. The last drive was a cold start driving 1km from a friend's house home. The next day I couldn't start the car.

It cranks normally and I can smell fuel. Primer click when turning on electricity happens too. I've tried some unflooding by pulling the EGI fuse and cranking but no luck (might need more attempts maybe) but has worked much quicker before). I'm afraid starting the car that day pretty much frozen could've damaged the engine, maybe an apex seal. Any idea what I could be dealing with?

 

Pull the plugs and check the tips and clean them off. Should always have a spare set of plugs for this scenario.

ive had some cars flood and I just needed to get plugs in not soaked in fuel to start. If it does start, monitor it or just check everything. If you’re worried about apex seals, might as well pull the plugs and listen for compression pulses.

 

When its very cold outside, these cars can flood quickly, especially if the battery is already a little weak.

I would remove the spark plugs, clean them and dry them and perform a proper deflood procedure on the engine.
