it started idleing rough with no power and puffing alittle smoke..got worse and worse through the week ..now it wont start at all!!!

new batteries ..so it turns over and batteries sound strong..and sometimes it sounds like it wants to fire ..but it wont..so wtf.. i need help..

What and How should i check..pics or diagrams of where stuff is located would be amazing thanks everyone//

FICM? ICP? Crank Sensor? HPOP? ...what yall think it could be.. ah im stressin out..NOT EVEN MADE THE FIRST PAYMENT ON THE TRUCK

[the06wildebeast]

FICM. That's exactly what my truck did when mine bit the dust. Check your volts.

[Guitarhead09]

ok. so check the volts when cranking? also can you buy these new or do i have to have it sent out and fixed?

[the06wildebeast]

Yea. You can get them new from either Ford or check out Swamps Diesel.

update: called dealer,,talked to mechanic..he said never had this problem out of truck...and also he said no way i could check i needed to get it scanned by a dealer ( and they have the scanner)..and he also said could be HPOP . or FICM..to much to list just need to get it scanned..he was no help at all...i traded a 05 mustang gt 70,000 miles for this truck..and that thing was perfect you could drive it to across country and back no problem..and i bought this truck and started idling rough after two weeks and now wont start..i havent made first payment...

[Guitarhead09]

he also said could be the egr...BUT he told me they put an egr delete kit on it so now im really at a loss...i honestly dont know what to look for at an egr delete..is it obious

---------UPDATE--------------

:
checked ficm- 48.9 volts when turn key on, and stays the same while cranking...

Oil pressure while cranking fine...

Checked fuel filters ..top of engine full of fuel..and bottom one looked good too

HOWEVER: after checking FICM..turned key on and guages tached out then went back down.. and after i checked the bottom full filter my fuel gauge said i had no fuel ..and before i had a quarter left and i also added 5 gallons as well just incase i was low...

so...

whats next step to check for...

im def buying a monitor ..like edge insight or something...ha ..

help me get my truck started pleaseeeeee lol
