Runs fine but it is hard to start when cold

Hello,

There are several reasons why an engine is hard to start.

It could be due to a weak fuel pump, a faulty fuel pressure regulator that does not work properly when cold. Dirty throttle bore, worn out spark plugs, low engine compression.

The best course of action would be to take a look at each possibility and take appropriate action.
Like clean out the throttle body, check the fuel pressure when the engine is cold, change spark plugs etc.

Here is a helpful guide:

This engine should have 56-62 PSI of fuel pressure.

Please let me know if you have any questions.
Thank you.
