Dodge Ram Idle and Stalling Problems

I was driving my truck today and suddenly the engine died. It was as if I had turned off the key. There was no indication there was anything wrong prior to this.

I checked the fuel pump relays and fuses for the ECM. It just cranks without starting.

Does anyone have any ideas?

    Do you have a bleeder port for your fuel system? I would suggest checking to see if you have excess air in your fuel system.

    I'm suprised :surprise: cummins diesels last forever.
    How many miles does it have on it.

    considering what u said Id say it has something to due
    with fuel pump or line

    Hi, I have a 98 ram 1500 5.2 4x4 and it was running great and then it just died almost as if I ran out of gas which of course I did not. I tried to crank it over but it wouldn't start. It sounds like its getting spark. Any ideas???

    First, try to determine if you are getting spark to all plugs, and/or fuel to the cylinders.

    I'm getting spark but no fuel. I can hear the fuel pump humming when I turn the key in the ignition. I'm thinking maybe its a clogged fuel filter??? However, I have no clue where that is located

    I can't remember exactly what year, but I'm quite sure by '98 model year the fuel filter and pressure regulator (fuel pump module) was placed in the fuel tank. If you're absolutely sure the pump is trying to operate, the tank will have to come down.

    I would check for a failed Automatic Shut Down (ASD) relay or an ASD open fuse (either 20 or 30 ampere) in the Power Distribution Center (PDC), first. Check the PDC cover for location of the fuse and relay. If you cannot locate a problem there, I would recommend performing the fuel pressure test first.

    NOTE: If the engine has been shut down for some time, fuel pressure in the fuel rails may be diminshed and the test will be inconclusive. Then the fuel injectors should be checked using Noid lamps.

    1. With the engine off and the ignition key removed, disconnect a connector from any fuel injector.

    If DC current is maintained too long it will overheat and burn out the injector coil.

    2.Using two jumper wires and the vehicle battery, energize the fuel injector for no more than a few seconds.

    Fuel may be under extreme pressure. Wear safety glasses and be prepared to absorb fuel with a large rag.

    3. Locate the Fuel Quick-Connect on the fuel rail.

    NOTE: On Dodge trucks the quick-connect is usually found on the fuel rail on one bank of the engine. The other bank will have a fuel pressure test port that includes a small metal cap. Do not use the pressure test port to relief pressure.

    4.Disconnect the fuel line quick-connect. If fuel is discharged then the fuel rails are receiving pressure. If you've got fuel pressure then you've probably lost electrical power to the fuel injectors. Check for a failed Automatic Shut Down (ASD) relay or an open fuse (either 20 or 30 ampere) in the Power Distribution Center (PDC). Check the PDC cover for location of the fuse and relay.

    If that's okay you might have loose connection somewhere in the harness or a failed Powertrain Control Module (PCM).

    Good luck & Best regards,

    check your carbon can, and make sure your gas tank vent is not clogged

    Well we lifted the bed up on the truck and replaced the fuel pump. My only question now is that the pump makes a constant humming noise which in my opinion is really annoying....I wasn't sure if this was normal or not?????

  • dustykdustyk Posts: 2,931
    Hi Donna,

    In-tank fuel pumps are quite noisy and when you're very near the pump (especially if you still have the box lifted) it may sound unusually loud to you. The test is can you hear it inside the cab? You shouldn't.

    By the way, if you've lifted the box I'm assuming you removed the box mounting bolts. Please be aware that on Dodge trucks the box mounting bolts are a one-time tighten only. If you try to reuse the bolts they will loosen and the box will move around on you. New bolts are required when ever the torque has been reduced (loosed) on the bolt.

    Best regards,

    I am trying to fix a 2001 Dodge RAM quad cab 4x v8 5.9 that is killing when it idles. I think I need a piece for the accelerator or possible a cauberator piece. Does anyone here know what that part would be called? I looked up parts for the truck and couldn't come up with anything except an "idle control valve." Thanks!

    I have a 2002 Quadcab with 4.7 engine and about 106K miles. Lately, when I start the engine it surges, (i.e. revs to about 1500 RPM then idles back to about 700 RPM). It will fluctuate back and forth for a bit before idle finally smooths out. Is this a sensor problem? Or a dirty throttle body?

    I was finally able to get a Haynes manual. In the tune-up section, it states in several places not to clean throttle body with carburator cleaner.

    I'd appreciate any suggestions.

    Idle Air Controller was dirty. I removed it and cleaned it good.
  • i have a 1996 dodge Ram with the 5.9 and it will fluctuate between like 450 RPMs and 700 RPMs and when im in reverse if i dont keep my foot on the gas every once in a while it dies. Im not sure how to fix it. another problem is when im sitting at an idle it feels like its missing horribly, and i changed the plugs wires cap and rotor but the truck has 187000 miles on it so i dont know if its the timing chain is stretched and thats causing it or what it is so if you have any ideas let me know. thanx
  • dustykdustyk Posts: 2,931
    I don't believe a stretched timing chain could cause this problem.

    My first suggestion would be to thoroughly clean the throttlebody, check for a clogged PCV valve, and also check for brittle and cracked vacuum hoses.

  • i have a 2003 3500 and some times it will not idle and i noticed that volt meter read low after driving a few miles it will start idling ok and volt meter reads ok
  • when i start it up sometimes it will idle fine sometimes it will not ;; had battery check also had alternator checked
  • I have a 2000 Ram 1500 318 automatic. Will loose power and misfire really bad. Hooked up to hand scanner pending codes were multiple misfires on cylinder 1 and 3 and lean on bank one. Towed to shop and ran fine when got there. This has happened about four times. No vacumm leak at intake. All new plugs, wires, cap and button. ECM okay. Good fuel rail pressure. Dropped tank and check fuel filter and pump.

    The engine starts ok, but after about 2 minutes it misfires/no power for about 1 minute (occasionally stalls), then it settles down and runs ok. This happens with the engine either hot or cold, after every start unless it is off for only a few minutes. The scanner says it misfired on cylinders 4 and 8. Any advice appreciated - I was told to replace plugs/cables etc. but I'm not so sure. Thanks.

    ps. about a month ago, it would start real rough after a rain, but this seems to have disappeared? - not sure if this is related to the above problem.
