2004 FX45 has troubling starting

[Robbie Friedmann]

I have a 2004 FX45 and I have to pump the gas pedal many times before the car will start. Once the car has run for a while it starts up fine the rest of the day. It does run really rough and I cannot gun it into traffic because it will bog down. My brother seems to think it is the Mass Air Flow sensor. I did clean the current MAF sensor with special cleaner but it didn't help. A guy at Advanced Auto Parts said for me to replace the full injector seals. He said the gas intake is losing pressure and that is why it takes a while to start. I am a do it your selfer and would appreciate a few good places to start. Thanks, Robbie

Have to tried to pull any codes?

I forgot to mention there is no check engine light on. Will I get a code if there is no light?

May want to take a closer look at the throttle body and clean it if you have not clean it before.

I cleaned the throttle body. I put in a new Mass Air Flow sensor. Still has a hard time starting in the morning and is sluggish when I pull out in traffic. I have run a couple types of fuel injector cleaner and Sea Foam. I would love to hear any other recommendations

Check your CATS maybe? Could be plugged. You have 4.

When I cleaned my throttle body I had similar issues. I had to do the throttle pedal dance.
