2002 Ram with 5.9l gas wont start.
I got back from vacation tried to start the truck, and it would turn over for about 1 second and die. I am getting 44psi of fuel pressure so the fuel pump is still working, but I cant find the fuel filter to see if its clogged up or not.
Does anyone know if these trucks have a inline fuel filter or is it all together with the fuel pump?
Could any sensors be causing this to happen? IAC? or EGR?
I know the pressure is lower than what it should be (50+/- and as low as 45) but the truck should still run if its getting 44psi right?

it will run @ 44.. it won't be as happy about it though..
there is no EGR on yours.. nor is there an inline filter in the fuel line..
other than the IAC, the coil is suspect.. it's unfortunate that they don't just up and fail, but do funny stuff in the meantime..
you may have an unregulated vacuum leak.. check your vacuum lines.. it would have to be a big one leaking to cause a no run situation- the easiest thing to do, after you eliminate the IAC, and visibly looked for a unplugged line, is plug each port on the manifold and see if it idles at that point..

nah. No need for that just yet. Still within tolerance at 45 PSI.
Might be just a dirty throttle body. Pull the air filter housing off, and have a look down the well right behind the throttle bores, if it's really nasty in there, that is more than likely the problem. Remove the throttle body, pull the IAC out, and clean all the gunk out of there. (have the battery disconnected while you are doing this.) You can get a t/b gasket for like 2 bucks at just about any parts store.

the IAC itself can be shot with TB cleaner too.. and a tooth brush works.. wiped out when finishing.. the port the IAC goes into is the important thing- same thing.. it likes to gum up.. try not to manipulate the plunger on the IAC itself too much.. I hear the mechanism is easy to break..
there is a little donut gasket on the thing.. don't lose it!!
