Before you buy a lift pump you might take it to a shop where they can put a fuel pressure gauge on it. If thats not the problem ...I would guess its the MAP sensor, also called the BOOST sensor.

I have an 07 2500 with the 5.9. I have it BullyDogged with 5" exhaust and AFE stage 2 intake. I have had it on my truck for the past 2 years. About 3weeks ago when merging into traffic or getting "on it" a bit i throw an "overboost" code. I called Bully dog and they told me to put a boost fooler on it....is this right? I even set the truck back to "stock" and it still throws this code....please help me with more answers.

Since this is a discussion for the Cummins engine, I have moved the threads for the AC system over to the Dodge Ram Climate Control discussion and you can continue there.

How high is your boost getting? On a factory cummins motor you should keep your boost from going over 45psi. Anything above this you will need head studs to prevent a blown head gasket or other problems. It is not designed to handle higher boost from the factory. This is why I would not get a boost fooler. Your truck should have some kind of factory waste gate to prevent over boost. The computer controls on the truck should not allow your boost to get over a certain level. And since It still does it when your programmer is off I would think something in that area may be having a problem. I have an 06 and my boost will not go over 41psi stock or programmed.

I do not have a boost gauge on my truck to tell me how high its getting. I was also informed to check my MAP sensor...is this tied into my wastgate opening? How would I check this?

I have an O7 that does the same thing (with the lights dimming). The Diesel mechanic at my dealer said to me that it is perfectly normal.

You want the Dodge Ram Climate Control discussion. Lots of info on this very issue. (This discussion is for Cummins engine-related problems.)

2001 Dodge Ram not getting fuel to injector pump by doublecreek
Jun 25, 2009 (8:25 am)

My 2001 Cummins 2500 Ram will not start. I am not getting fuel to the fuel filter cannister and I have already replaced the lift pump. Is there any thing besides a clogged fuel line or stopped up pickup that would cause this. I think pump should run for 2 seconds when I turn the ignition switch on. Any input would be appreciated before pull the bed off to access the fuel tank.
