#297727 Sounds like a main relay to me.

Does it make a click noise before you start the car?

#297743 Yeah try the Main relay first! You can take it out and re solder the joints inside. Mine did this too in the summer time. I took mine out and re-soldered it. Haven't had the problem again.

Let us know if this helps if not just post what your car is exactly doing when this happens. :thumb:

#297775 i just had a very similair problem!

i tried new main relay and a bunch of other stuff turned out to be the coolant temp sensor not letting the car start when warm.
