Try turning your key on then off then on and then off and then leaving have the same truck when you do that key sequence under the odometer it should give you a code or a messagewrite it down and go from there. Always try this before jumping to conclusions about actually spending any time or money.

fuses are first. or read the manual here. https://eautorepair.net/Marketing/Default.asp

Most likely your system just needs to be charged with r134a coolant. You can do it yourself. Just head down to the local auto parts store and buy a can of coolant that comes with a hose and gauge attached and then locate you low pressure port on you system. It is typically located on the passenger side between the radiator and the firewall on a silver tube. Don't worry you can't make a mistake as the coupler will only fit the low pressure side. When you locate it remove the cap and hook up gauge and can. Start the car and turn the AC to mac cold and highest fan speed. Then open the gauge depending on ambient temperature out side your gauge should read between 35-45 psi. The gauge should also be color coordinated as long as you don't fill until the gauge is in the red. Your good. Then close the gauge, remove it from the low pressure port and replace the cap on the port. (When the coolant is flowing into your system the can should turn quite cold and maybe even have some frost on it. No worries that is normal).

I have 2004 Dodge 3500 w/ 5.9 Cummins , at about 80,000 miles I had excessive oil fumes coming from underneath the hood of the truck . Fumes came from the slobber tube . Took it to the dealership . At first they replaced the fuel rail . Problem got worse . Took it to the dealership again , Oil pan dropped , engine head removed , fuel tank checked , at my cost at first . Results , number one piston top pitted like some took a pick axe to it , parts of piston rings missing , number six piston top clean , but parts of the rings missing as well . This took 17 days for the dealership to find out and to agree to have the engine repaired under warrenty . 14 more days to order and install new engine and turbo . 31 days in total to repair an engine that is defective . Two other engine were in the shop at the same time with the same problem . I now have 100,000 miles on the truck and only 20,000 miles on the new engine with the signs of the oily fumes showing up again . So , rings crack , pieces make their way out of the engine block thru the turbo , back pressure in the crank force the oily fumes out of the slobber tube . That has been one of the problems I have experienced with my Dodge Ram . I am not impressed with my 2004 Dodge , however , my 1995 Dodge Ram was great . Is the new Cummins Engines a true diesel with a replacable cylinder sleeve ?

I hope that this is not your problem , but the fastest way is to check compression in each cylinder and crank case pressure .

Its more then likely a wheel bearing. Try taking it down the highway and turning left and right erratically. Almost like a swerve. If you hear the noise I would put money down on the wheel bearing.

Depends what the rattling is really... If it's the engine , could need a valve adjustment... I've also heard of torque converters make a rattle when going bad, but only when in drive or reverse

Could be low on compression, or torque converter may be slipping

No Cabin Air filter listed in NAPA's catalogs.

Try this.

James, Since you are pulling a vacuum to draw the fuel to the fuel pump a very small pin hole will cause the pump to not draw fuel. On my Cummins I connect a fuel line to the tank side of fuel pump and ran it into a pail with diesel fuel to verify an air leak in the line to the tank. The ECM electronics control module on mine a 1999 turns the pump on. You could use a jumper 12 volt to the pump verify it is getting 12 volts. You should be able to hear it running. I replace the factory fuel pump on mine with a Fass pump and used a small relay to power the Fass pump without using the ECM and it works great. Keith (waymaker10)

Check the crankshaft sensor. any codes?

You should check out www.reliable-store.com they have info on repair, service, wiring diagram, electrical diagram, fuse diagram, torque specs, troubleshooting, PCV, gear box, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

I've had it happen to me more than once and I fix the issue over 50 x what's going on if your fuel pump is going out it's not going out it's already out and once you replace your fuel pump and your fuel filter your car should be back to normal home skillet

Check compression and fuel pump injector pressure.

Most likely culprit is the blower control module/ resistor. It is the part that controls the blower motor speeds.

-Possibly the battery is not strong enough to crank. Try high CCA battery. For example now the one you have has CCA 750 How about change to the maximum that they carry. Good luck Mai

USUALLY A SIGN OF OVER DELIVERY OF INJECTOR PUMP IS THERE EXCESIVE SMOKE FROM EXHAUST ?

How many miles are on the truck usually around 100000 miles you will need to replace the O2 sensors not hard to do the engine wont stop but fuel mileage will begin to drop and power will start to go down. You may not notice the power drop to much are the fuel mileage drop. To find out if it is indeed the O2 sensors take it to auto zone they will put a tester on it and tell you what it needs. Good luck o and they wont charge you anything for the test.
