Question type: Maintenance & Repair
Ok so i have a 04 f150 2wd, it was spitting a code
po191 fuel pressure senser, so i replaced that,
truck would start, run for a min then dog down and
die, so i changed the fuel filter, again same code
plus additional codes po171 po174, so basically
the truck would start run for a min the die, and
wouldnt restart right away, let it set for a min then
it would start but keepa doing the same thing, even
worse when i give it some gas when its running,
what other things could be causeing this

None of the lines are leaking, how would i have gotten a vaccum leak? And how would i go about finding where its leaking?
Yes it will run at idle for maybe 5 mins then dog down and stall out, and wont restart unless it sits for couple mins, then does the same thing again
when idling, spray brake cleaner around intake and all vacuum sources,if you have a leak the engine idle will react,it will rise,lower or die. Also did you check the fuel pump module for clam shelling?
Yes i checked that and it was fine, but i will try that, thank you for your help
Ok so ive tryed to see if there is a vacuum leak, and there is none, what other options do i have?
