Civic 2.2 Ctdi , 2009 fails to start with a warmed ECU

Hi!

I Have a civic which will not start when warm and Iím seeking for some help.
I found out that by only warming the ECU to approx 40C with a hair dryer or heat gun it will fali to start.
When cooling back below 40C it will start without problems.

Also if the ECU is warmed up by normal use (driving for 10 minutes), if I stop the engine it will not start again.
After cooling the ecu it will start again.

The car once started it never fails during drive, it only fails on start with warm ecu.

When it fails Iím receiving VSA, ESP, Airbag, Tire pressure, engine, triangle errors and the avg speed and avg fuel consumption are cleared.

Error codes are b1168, p0602 but I could not find any problems related to it.


Any suggestion what could be wrong?


Many thanks in advance!

plenty of threads on the over-pressure relief valve or the fuel pressure sensor

Hmm, how is an over-pressure relief valve or a fuel pressure sensor related to starting problems when an ECU is slightly warmed (not warming the entire car, garage etc.....)

However, can you please link a post?

Thaks!
