I have a 96 Honda Accord. I have to pump the gas pedal before it will roll over?

Wasn't a problem before, but it takes longer and longer to roll over the more humid the weather gets. What's the problem and how much is this going to cost me?

Dogs roll over. The starter cranks the motor over. If the plugs fire and you have injector pulse it should start. A broken timing belt or one that jumped will keep the motor from starting. Have you even tried changing the fuel filter yet? Then you need to do a fuel pressure test.

Please explain, "roll it over". Are you foreign or something?

The pumping of the gas pedal only lets in air and sends information to your onboard computer from your throtel position sensor. Your problem is either your mass air control which could just be you need to clean it or replace your air filter as the humidity will cling onto dirt on the filter or Mass air control and restrict the flow of oxygen or give false reading sent from the mass air control to the computer which is part of determining how much gas to let in to burn in the cylinders. In other words you need gas and air to start and run as engine if you restrict either of them it won't start efficiently. Replace your air filter and buy a can of mass air control cleaner fro the auto parts store and clean the wire grid in the air feed.

Check the air filter.

Well, if you keep rolling it over, your insurance company is going to charge you more or cancel your insurance.

These answerers are are technically right about pumping the gas. But if it did not work you would not be doing it. Your not stupid. Your Honda is having main relay occasional weakness and will worsen in the heat. That is what they do. It controls the fuel pump. When your are pumping the accelerator the fuel pump is trying to charge the line ahead of time. I bet sometimes your are turning the key off and on to. This gets that sluggish relay going too. Turn on the key and listen for the pump with the music off. No hear pump no start. Hear pump and vroom. 150.00 installed.

Pumping the gas pedal is a waste of time. That only worked on older carbureted engines.

If you are convinced it's actually accomplishing something, go ahead and pump.

Your car probably needs a good old fashioned tune up.

No idea on cost but it sounds like the heat and humidity may be causing linkages in the fuel control system to stick so that the proper fuel supply is not available for starting. Talk to an auto parts store about what kind of spray cleaner you can use on the linkages. If spraying solves the problem, then you are probably under $50.
