check battery first make sure is fully charge

Check that the throttle cable is not too tight

Hey guys, so I've got the 2003 dodge ram 1500 3.7L v6, I've always dreamed of having me a blacked out dodge ram and finally got it but damn I found out real quick why I got a good deal, the ball joint's and tie rod ends were well let's just say wayyy past their expiration, the tires were from first glance not bad but close look had bald spots so had to get 4 new ones, but I'm rambling my issues I need some input on are 1. Squeaky belt/fan?? I have greased all I could grease without covering serp. Belt and yes, the belt is like brand new I've seen others with similar problems and researched and searched and nobody has came out with a solution!? 2. With this type engine and exhaust system... what's some reasonably cheap things I can do to enhance performance and torque, i have acquired the tune up chip and fuEl treatments, transmission treatment as well! Guys any feedback would be very appreciated thanks!!

Clutch or release bearing needs replacement.

Not too sure what a (2077) is. But as far as the motor is concerned. I would take it to any local auto parts store and have them hook up their ODBII tester. This will identify the fault codes that are obviously happening. Given this new info. you can now make informed decisions on what to address first. My guess is that the "throttle position sensor" is BAD. AND/OR the "mass air sensor" has issues. If all that gets you no better off, look at the ECU (electronic control unit). It literally regulates all motor performance. Hope this helped, Jason

Look at your air conditioner vent coming of the evaporator. Open hood and should be a 1/4 inch hose right by firewall on drivers side. They rarely leak, but sometimes fall off and normally discharge to ground. Be careful and depending where you live you can turn ac on and just wait to make sure its draining on the ground. Turn truck off and look for loose hose.Please be careful as there's lots of places you can cut yourself. I don't think it's the door gasket if you had a pro do it.

Pressure test cooling system for 30min . Pressure should remain at 15psi if it drops search for leak with
a bright flashlight. Be patient and good luck with your vehicle.

Do yourself a favor an take it to a qualified repair shop .

It is really a simple set up that makes a car run. The components involved are as follows, Computer, temperature sending unit, oxygen sensors, throttle position sensor, fuel pump and a few others that help complete the process. The fuel pump keeps the fuel pressure to 44-55 psi . The injectors are in the closed position and can only be opened with an electrical pulse. The pulse is sent to the injector by the computer. The length of the pulse is determined by the information given it by the temperature sending switch and the throttle position sensor. The computer see how hot the engine is and how much throttle the driver wants. Then it sends the current to the injector, pulse time, that opens the injectors for milla seconds. The oxygen sensor measures the amount of air in the exhaust and sends that result to the computer which analyzes all the information and makes changes to the pulse time and makes the changes to have a fuel mixture of 14.7 to 1 ratio of air to fuel. This happens about 20 times a second depending on your speed.

Just a hunch - remove the injectors and clean them to insure there is a path for the fuel to get into the intake manifold.

Hi there... Sounds life aftermarket work was done to your truck..... or it has drastically malfunctioned....... The electronics in your car were not made to be codependent upon the engine. Everything works in unison and has a job. So the electrical system shall have nothing to do with the engine warming up, if the engine does not start this would prevent starting the alternator and would not charge the battery, eventually the battery goes dead and you look for why, but I think your barking up the wrong tree on this one..... Maybe something else is happening that is coinciding with the ending warming up thats affecting your electrical system. It must be operating somewhat normal because the truck would not start if not, as for the engine IS dependent upon the electrical system and the electrical system is only partially dependent on the engine (the engine must run to run the alternator which charges your battery). If you asked me I would say you have a bad connection at your fuse box (if you do not have aftermarket work(if you do have aftermarket work start at your weakest connection)) or other faulty connection- I think your getting normal power but your accessories and instrument panel have a short somewhere, also the battery may have enough juice to start the engine but not to run the accessories until it runs a bit a charges a bit, you turn the truck off and it sits dying more so when you go to use it, theres only enough to start the truck? idk but this should give you a good start and good luck to you

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few for now u can try reliable-store .... let me know if u need help thanks

could be the ignition switch. It's definitely an electrical problem, and the ignition switch is the most likely cause.

Intervention Regeneration Strategy - EVIC
Message Process Flow (Catalyst Full Message)
(6.7L Diesel Engines Only)

Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards, resulting in the
lowest emitting diesel engine ever produced.
To achieve these emission standards your vehicle is
equipped with state of the art engine and exhaust system.
The engine and exhaust aftertreatment system work
together to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seamlessly integrated
into your vehicle and managed by the Cummins
6.7L engine Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust system's
catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance required
on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

Perform Service
The 6.7L Cummins engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR Valve and a EGR Cooler.
This system filters and recycles gasses produced in the
crankcase during the normal combustion process. Perform
Service will be displayed on the overhead console of
your vehicle if the CCV filter, EGR Valve and EGR Cooler
is due for required maintenance. The CCV filter is located
on the top of the engine valve cover. For additional
information, see your local authorized dealer.
Catalyst Full See Owner Manual
Catalyst Full See Owner Manual will be displayed on the
overhead console of your vehicle if the exhaust particulate
filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your Cummins engine and exhaust
aftertreatment system may never reach the conditions
required to remove the trapped PM, if this occurs Catalyst
Full See Owner Manual will be displayed on the
overhead console in your vehicle. If this message is
displayed you will hear one chime to assist in alerting
you of this condition.
Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.

By simply driving your vehicle at highway speeds for as
little as 45 minutes you can remedy the condition in the
particulate filter system and allow your Cummins engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an extended
period of time after the initial warning notification,
the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.

CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it's capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horsepower
and torque output.
The PCM derates the engine in order to limit the likelihood
of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.

Better check the alternator diodes. Good luck.

Try connecting power directly to the horn and see if it goes off. If not, it would seem it needs replacing. If it works, maybe the horn switch on your steering wheel is broken. A simple process of elimination.

It was given to the new car owner of the truck with the owners info packet, if you do not have it contact the Ram dealer for help.

You should disconnect the battery first as you appear to have a short. Look for a broken or damages wiring harness around the fender. Where does the ground originate that you had taken "loose"? Did you fix anything recently or hit anything? Did you check that the red (positive) cable is attached to the positive (+) terminal on the battery? How much voltage were you seeing at the fender? did you test with a test light (tests the voltage potential under load)? Is your ground cable from the battery to the chassis and to the engine in good condition with tight fitting bolts?

it's none of the above. dodge doesn't like to do a good job on the ground system. if you beef up the ground system most particularly from the back of the motor to the frame and be sure your making great contact from the battery to the engine and from the engine to the frame your PCM wont go out on you. bad ground creates resistance and will cause the pcm to go out. it's not your fuel pump, pickup coil tank case sensor or iac. tell tale sign of this condition is you have to do a key dance to get it started ( no it's not your ignition) stalls when running down the highway and or will run rough and possibly backfire after it was just idling fine. The PCM is babbling to the engine. Sometimes the iac will cause it to run rough if the end is dirty but what I explained is the usual issue. PCM 300 dollars. I did not return old one for core $70 because a dealership can reprogram the pcm if it's not burned out because of the poor grounding system. Thanks Dodge. ??
