Exclamation 2002 4.7 wont start

2002 1500 4.7 v-8 100,000 miles

will start/run fine in the morning, then again 12 hours later, then after sitting for 1-3 hours if you crank on it, it acts like it isnt getting fuel, you have to mash on the gas to get it to start, then keep on the gas for a few sec to keep it running. After that it runs fine again.

All driving times are 5 min give or take

no codes come up on the spedometer

it did have the fuse blown for the A/C fan (i think thats what it was, i looked up the code on here and replaced the fuse, hasnt blown since) It had been blown for a while before starting issues, check engine light was on, starting problems started before i replaced it, and continue after.

thanks for your help

I am also having this issue on my '05 Hemi. Depending on how long it's left to sit it takes either a little bit of gas or basically mashing the pedal down to get it to start.

It's not related to plugs, it's not fuel pump, it's not fuel pressure regulator, it's not the throttle positioning sensor - or anything to do with the throttle body for that matter, it's not the IAT sensor either. Just about the only thing I haven't looked into yet is the injectors but that'd be a bill i'd rather not like to chance not working.
