It is taking long for the engine to run. It had issue with water pump which failed. After replacing gasket and water pump check on computer diagnosis no problem is detected. So why the hard start?

It sounds like you have a vacuum leak or a MAF sensor that is going bad.

Here are three guides I want you to go over and try:

and

https://www.2carpros.com/articles/how-to-use-an-engine-vacuum-gauge

and

Please let us know what happens.

Cheers, Ken
