Default problems starting

for the past few does it has taken me about 5 minutes to start my jeep. all electrical stuff is fine but it just wont turn over and start when i turn my key. to start it i have to floor the gas pedal and then once i hear the exhaust kind of start puffin i let off the gas. once i do this several times it starts.
i was thinking maybe i need a new fuel pump?

anyone got any suggestions?

thanks jordan

Check and clean the tb,injectors.Check your fuel filter and lines going to it. When you turn the key can you hear the pump cycle? Also check and replace the air filter if you havent lately.

Also wouldn't hurt to check your spark plugs. Hell, just replace them while you're at it if you haven't done so in a while. Use the cheap Champion plugs, they work the best.

Alright thanks guys i'm definitely changing my plugs and I'm just gonn buy a k&n and I'll check all the others as well

i also forgot to say that once I get it started it will start no problems all day after. It's just in the mornings after sitting overnight when it has the problems
