I have a volvo 2001 v 70 - ocasionally on starting I have a very short delay about a second or two and then it starts. The rest of day - no problems. I replaced the ignition coils and the spark plugs. Help.

 

Owners manual: https://www.customers.volvocars.com/...0/01v70_00.htm

The manual says it's not uncommon for the car to crank for up to 10 seconds before starting: https://www.customers.volvocars.com/...0_06a.htm#pg80

Where are you located? Is the car left out in the cold, is the battery a little weak? Has the battery cables been cleaned lately? How long have you owned the car? How long has this been going on? When you turn the key does anything happen? No one can help you will such little info.
