[initial_g]

My m20b25 is haveing starting issues when warm. Ive had the inlet off and replaced all the gaskets with new ones cleaned up the tb and the maf sensor, it starts perfectly when cold but when warm... even after it just idleing for 5 mins from cold .. switch it of then it wont restart :/ any ideas?

How is your fuel consumption?

Is it worth testing the blue temp sensor for resistance readings? The wiki has a guide iirc.

[mark_i]

main relay (white) and ECU relay (orange) can cause the warm starting issue

Ive not driven it yet so not sure on fuel consumption. Its not been run in 2 years....

If it's been sat for two years then the ECU won't have any of its idle settings sorted and is probably massively overfuelling.

I posted this elsewhere yesterday:

After resetting the ECU, FROM COLD start the car up and let it idle for ten minutes. Then turn it off, restart, and take it for a very aggressive drive.

You should still test the blue temp sensor at the ECU plug though, to make sure the signal's getting through.
