Customer: replied 1 year ago.
its hard to start from I guess 40 degrees and below. I've just had my engine rebuilt and ive noticed its been doing that since the start of the cold weather. could it be the intake valves to do that in the cold weather?

it takes from 5 to 15 minute to fire up.

The intake valves can cause a hard-start cold if they had carbon built up but not for 5-15min. It would be 10-15 seconds or so. They should have been cleaned up when it was rebuilt anyway. The basics need to be checked like fuel pressure and compression. If either is low it will have a problem starting when cold. Since it started after the rebuild I would have the compression checked. Another possible cause is a bad engine coolant temperature sensor(ECT). If it's not sending the correct temp to the engine computer it will start hard or take a while to fire up. Fuel pressure and compression testing is a good place to start, they need to be ruled out first.
