Posted this on the MR2 board (as you would expect) but since people are obviously a fair bit more knowledgeable on here, I thought I'd post it up anyway.....


Okay, quick run down of the probs.

Car was sat for about six weeks up until last week when I tried to fire it up. Low battery meant it flooded, so after much messing around with plugs, it finally fired up, albeit with a real struggle.

Ran it for while, warmed up and down, fans in and out etc, then put it away.

A week later (this morning), fired it up, ran it round the corner from where it's stored, and into the drive. Switched it off. Now it wont start again.

Seems to be overfuelling like you wouldn't believe! You can smell the vapour, plugs are coming out sopping wet.

Ignition all seems to be in order - just seems to be permanently flooded! It's never done this before, but has always run like dog from cold, so I'm wondering whether the coolant temp sensor may be on the blink.

As such, can anyone identify these three sensors on the thermostat housing?





Wondering if it might be some sort of cold start/enrichment issue, as I've never had it not start like this.

Help please!
