OK, I will talk to my local dodge dealer about the manual, thanks for the link!
mrmopar, you are absolutely right about where the lift pump is, under the fuel filter, above the starter,, in a nice hard to reach place.. haha I'll try your test with the drain. You wouldn't happen to know what the pressure coming out of the lift pump should be, would you? If it read the right pressure, then it should be OK, right? or is that pump more volume related than pressure related?
Today I put in a new fuel filter, old one was pretty bad and now it's running a little stronger. That miss I had talked about seems to be getting less and less over the past couple days, but changing the filter did not make it go away completely.. I sure hope it's not the injector pump,,, the injector pump looks really new,, also, somebody had the head off of that motor I'm fairly sure, because the freeze plugs in the side of it look brand new.
I noticed something new about that miss, let me run it by you guys..
As the motor sits and runs,, you can hear/feel it "cycling",, you know,, kind of changes pitch, like you just turned the a/c on or something,, it's a normal occurance as far as I can tell,, something having to do with the way it runs or heats the fuel,,
anyway,, it idles just a hair slower during this period
Everytime I am going down the road(60 mph spd limit) and come to a red light, as I approach it, I'll put it in neutral and coast/brake to a stop.. Every time I get just below 10 mph, I feel that change in the idle,, the "cycling" I mentioned earlier.. maybe it's a computer controlled event? seems normal, that doesn't worry me.. but I did notice that is the only time I really notice the miss. idleing when cold doesn't do it, or just slow driving through town doesn't do it either.
Get this,, I thought a lift pump was going to be about $150 like everybody told me, called mopar today,, $345!!! They just raised the price.. the guy on the phone said it was because most trucks with that model pump were just coming out of warranty and the company wouldn't have to pay to fix them anymore.. isn't that a load of crap?!?! Would be real nice to know for sure if mine's bad now, before I go cough up that much $$.
By the way, mrmopar, I work at the other end of the production,, I work in a Dodge plant where all we build are Ram trucks.. we currently do not build the diesels, but are getting them back at model change.
Thanks again the the help/info!!!
