    Air filter is off ,

  • oldlamplight May 17, 2009

    It just quits running when it warms up to normal operating temp. Let it cool down and it runs again til you stop at a stop sings, then you have to floor the gas peddle to get it started, black smoke comes out of the exhaust, clears up, put it in reverse or drive and it stalls right away. We have changed the fuel regulater also.

    It just runs til it reaches operating temp, stop at a stop sign and it quits. Floor the peddle and it starts , smoke comes out of the exhaust, clears up, put it in reverse or drive and it stalls. Restart, same thing. Let it sit till it cools down and it will start and run til you stop. Have changed the fuel regulator also. It is a magnum engine Ram charger 150.

    Hi Ourhowse

    Still

  • oldlamplight May 22, 2009

    Hi Ourhouse, What is the MAF and where is it?? Problem existed before and after changing all those parts except the timing gear. It don`t run very far before it quits, like 2 blocks, before it was til you stoped.Vacuum steady at 17. No crankcase pressure, no backfiring. Air filter new. Exhast has very little pressure, I would say it is normal. Mechanic replacxed timing parts. Timing light still says it fires before top dead center by about an inch on the flywheel. Same position as before the change. Thanks, Chuck

2 or 4 barrel?
If auto choke, chk yhat for opening.
Msnifold vac fluctuating or thats just the range? Sounds a little high. neck time you start the motor, give the throttle a snap and vck the coke play position Cold running the choke should be 1/4 - 1/3 open. If you need info on how to adjust let me know Hot, or at operating temp, choke should be wide open. Good luck.

    After deeper review, The Mass Air flow sensor may be the problem in as much as it sends cignal the ECU to regulate fuel demands... you said no codes, so unplug the MAF sensor and plug it back in. then see if you get a code.. I'm sorry, but I'm digging also to find your answer.

  • Ned C Cook
    Ned C Cook May 20, 2009

    Ok, this problem existed before you did any of the items you listed? did it develope since? Using a vacuum gauge does the vacuum pulse between 15-17 at an idle?. Remove the pcv valve and ck for crankcase vacuum. If crankcase has vacuum, Your intake manifold gasket is leaking. If vacuum pulses, You have a burnt valve. In either case the engine will run and tend to smooth out at cruising.. Damaged or leaking intake manifold gasket will cause some backfiring, burnt valve rough idle Check the Mass air flow sensor. It regulates or tell the ecm how much fuel is in demand. If sensor says no air then there won't be any fuel. Free air flow is a must at an idle ( clean air filter. I hope this helps. The last thing will be the ignition timing. How does the exhaust cime out the tail pipe? Does it feel to be drifting or forced out? I'm sorry, but all these things need to be chk'd. Let me know please. How is it for power? Feel strong? or gimpy?

    chuck;

    The maf sensor would be on the intake duct coming out of the air cleaner. The first sensor. Its function is to inform the ecu on how much air flow there is and the ecu provides the fuel proportionately. The reason for exhaust pressure is that if the catalyctic converter is restricted it will inhibit the combustion with back pressure which you can see the effect if you blocked the tailpipe. combine poor combustion and poor flow through the cylinders will cause the maf sensor to indicate there is no air flow and minimize the fuel provided.. Try this. Fire up the engine and run it till it for a minute or so then have someone shut it off. The exhaust should immediately stop. If exhaust continues for a few seconds than the converter is restricting.. The longer it continues to exhaust, the worse the restriction. You can use a tissue at the pipe opening to pick up any discharge you might not feel.. Let me know good luck

Then i think i'd be dumping some soapy water on the intake gaskets checking for leaks. ANd wiggle the **** out of all vacuum hoses. ( you probably did that) And if there aren't any, your cam could be tired. You got a tough one there. Hard to figure with a keyboard.

    So you know it's not the cam then i guess. And there are no vacuum leaks at all. Cool.Why don't you share with us what the problem is then?

    That was the problem. You were trying to run it without the air filter?

My 98 Dodge Ram 1500 with a 318 in it will stall at stop streets only when it is at operating temp. When it is cold it will not stall. The Truck runs good down the road.


Sounds as if you may have a MAP sensor reading incorrectly when warm and causes the stalling. You may also have a vacuum leak that is not noticeable during warm up or while driving.

92 dodge dakota stalling,running rough,loss of power


Did you replace the fuel filter when you replaced the pump ?
Was it running rough before the pump was replaced.
Did you replace the cap and rotor too ?
"Sucking a ton of air" could be a vac leak, or the sound of the throttle open when the engine is bogging down.
Is the check engine light on when it is running ?

check the engine coolant temp sensor for a disconnected wire, broken wire, or a bad sensor. If it is bad or has a disconnected or broken wire, the sensor reads engine temperature at full cold...like -40F. It will schedule way too much fuel for a hot start and the engine will flood. When you stop trying to start it and let all the extra fuel evaporate and the engine cools down, then it will start.

1992 dakota 318 v-8 automatic stalls when placed into drive,it will move forward when you start to roll down hill. but engine dies when you stop; but truck run fine in reverse


Maybe the IAC is bad and can't control the idle. I know many have that problem but only effects D and not N or R. If your NSS (neutral safety switch) connects the ECU it could give false reading and ECU kills motor but unsure about that truck. Many cars it only allows the starter solenoid.

I have a 92 dodge 4x4 with the 318...Fuel Injected.When it is cold in the mornings,it just turns over and over untill after a few minutes it just fires up and runs great.


fuel injected vehicles have a fuel regulator,if this has a leak in it,it will flood the vehicle over night or lose fuel pressure so your cranking is raising fuel pressure back up or spiiting out all the fuel in cylinders til it can fire,check the fuel pressure regulator

88 dodge ram charger 5.2 ltr engine....intermittant spark


I have a 1988 dodge ram charger with a 318 motor with throttle body. It runs really good when I start it up and drive it for about a half of an hour.
But after that when I step on the throttle a little bit, it hesitates. If I let off a little bit, it will go or if I really step on it, it will go also, but if I just hold it there, it really hesitates If I stop, the idle jumps up and down so much it causes itself to stall. It seems to only do this at low RPM's. If the RPM's are higher it's fine

1992 Dodge 250 van, 318, Automatic - Dies when coming to a stop


I cannot see how adding a fuel additive would help to be honest. I would be looking for a split or leaking vacuum line, I have even seen a leaking evap canister before that caused a similar problem. Does the engine pull clean and strong when it is warm or at cruising speeds? Does it feel like its running lean or misfiring?
