Suddenly experiencing a problem starting after it's been sitting for an hours or two. Outside air temperature is 70F.

Replace plugs today, cleaned ICV and the MAF looks OK.

Battery checks OK using multimeter.

Don't know history of fuel pump, or fuel pump sender/receiver or fuel filter. No fuel check value is installed on top of fuel pump sender/receiver.

Starts perfectly once it gets going and idles fine.

Any suggestions would be appreciated.
