House Please, l recently changed my accord baby boy fuel pump less than a month only to discover that when l engage the reverse gear and step on the gas pedal it doesn't respond immediately until when l pump it.

The same goes when am on a slope, to reverse it will delay.

Could it be fuse or relay?

Please your kind suggestions are welcomed.

Delayed engagement are usually associated with transmission issues. But we can conclude unless with proper diagnosis. Go to a good Auto Electrician, u get better repairs.
