2004 Dodge Ram - Answered Questions & Fixed issues

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.

Sounds like solenoid failing . Most of the time when solenoid fails it won't show on the code reader. U can read them with special scanner, but only if you know the proper numbers that will show when u read them. Most good transmission shops, have that tool and they can read it for u.

That's an indication of a stuck thermostat, not letting coolant circulate.

It maybe as simple as a bad radiator cap ! If not refer to You Tube !

No, not at Fixya. Do checks though. Beware of title washing with a vehicle like that one (trading through an intermediate buyer to sell a damaged vehicle) Get a history report like CarFax, it is worth it. http://www.nclnet.org/avoiding_online_car_buying_scams http://www.autobytel.com/car-buying-tips/car-buying-*****-tips/top-10-car-scams-while-buying-or-selling-100460/ .

Check your wiring. I know that these trucks have that problem mainly with the passenger side but I'm sure it could happen to the driver side as well. See what happens is they run the wiring through the door near the hinges and when you open/shut your door it wears the wiring causing it to short. My passenger side doesn't work with the passenger controls but will work on the master controls. I will be fixing mine here shortly.

Possible Causes: Transmission Control Relay harness is open or shorted - Transmission Control Relay circuit poor electrical connection - Faulty Transmission Control Relay - Faulty Transmission Solenoid/Pressure Switch Assembly Read more: http://engine-codes.com/p0888_dodge.html#ixzz3Z8ifNjHs I hope this helps! :)

The computer is not happy with the motor change. There is probably a security code system that needs to be reset. It may be as simple as the radio security code which dealer may have by vin number. But more likely the internal computer needs a reset, most likely also by dealer.

Try the following link. Only one tool is required. If the old one is not broken, pay attention as to how is routed before removing. 04 Dodge Ram 1500 Serpentine Belt Replacement 2004 Dodge Ram 1500...

fuel regulators are normally found on the fuel manifold and have a line going back to the tank of the inlet side of the pump

Open up the tail gate, you will see two torque screws on the inside beside the tail lights. take these out, this will free up the housing and you can change it from there.

That doesn't sound fun. What is the question? I’m happy to assist further over the phone at https://www.6ya.com/expert/josh_8f8ad0a8f7e0e6d3

If the clutch cycles on for a moment, then stops, and repeats, it's low on Freon. If it never even tries to spin the fuse my be blown.

We do not have the diagrams you need, they are copyrighted. Sorry.

I know I had the same problem with my 2004 3500 Cummins...try turning the key to the crank position and let it go (this will allow the fuel pump to run for about 25 seconds, basically priming the pump). Try starting the truck again, if it cranks over and sounds rough this is normal. Let it run until it goes back to normal. If you cannot crank the truck over keep repeating the process above (making sure you turn the key to the off position after each time you try). **This information I found out of my Chilton Dodge Repair Manual**

check that the connection to the computer is pressed full home and is making good contact. Run fault codes to find any faulty sensors. Reset the CPU using a code reader.

I would think the idle speed control valve is defective.

Sounds like the previous owner patched a hot wire to the rear lights instead of fixing the problem. Someone will need to get the factory wiring diagrams and start backtracking from the lights to the dash to find out what is wrong. You may need a shop manual to get the diagrams you will need. Most repair books do not go into wiring that deep for the DIY.
