Hi.

i have a problem with my car.
When I start the car in the morning for the first time it starts, but dies after 1 second. I have to try to start it 2-3 times before it starts after that the car runs perfect and will start every time all day until the following morning.

No warning lights on.

What could be causing this?

You may have a fuel pressure bleed back problem, try cycling the kek a few times in the morning leave it on run but don't crank it, turn off after a few sec and do again 2-3 times, if it then starts I would be confident that it is fuel bleeding back into the tank, cycling the key will bring up fuel pressure, at this stage, just starting as you would normally you may not have enough rail pressure to run, that why after a few goes the fuel pressure has built up and all is good until it sits over night.
