if you can expand on what all is going on perhaps we can help, as we all have the same problems from time to time.

however what you have said is insufficient for anyone to do anything other then answer your question.

So, yes I have had that problem.

first year I planted pepper seeds, I dont think I got any of them to germinate. I dont think I gave them enough time. This year just about all came up after close to 3 weeks even with a heating pad under them. They do take a lot longer than tomaotes to germinate and grow.
Just give them a chance.

Use a heat mat .They 're sold at Parks Seeds. I lived in zone 9 before and have grown great peppers there.I used tomato cages for my peppers because the became very large in Houston.

Peppers like the same as tomatoes, ideal is 86F/30C for germination

15 or so seeds planted in containers outside in soiless planting mix. temps have been in the mid 60s to high 70s, they have been kept in a small green house for 20 plus days with no signs of germination. I have more in small pots on the top of the fridge, 14 plus days with no germination.

Use something to warm the soil to 80F plus
