I have a 1998 Dodge Ram 1500 3.9L V6 2WD. Mostly when I'm almost to a stop (under 10 MPH), but also sometimes when I'm going 15-20 MPH, the truck will stall, but I still have power in the cab. I have replaced the ignition coil, the Idle Air Control Valve, and the fuel pump. I also added the SeaFoam engine treatment. After I replaced the fuel pump two days ago, the truck ran good with no problems or stalls (a total of about 4 hours running time). Then i get in it this morning, and its doing the same thing. Could it be a short somewhere? Could the fuel line be clogged? The only filter it has is the screen on the bottom of the fuel pump. I was told at the auto parts store that there is no in-line fuel filter. It just seems like it's intermittently not getting fuel. Or maybe too much? After it stalls, it takes 1-3 tries of turning it over (5-10 "engine rotations") before it starts, and a couple times I've smelled fuel in the exhaust fumes.

 

Do you have any engine lights? codes? What about your air flow? Did you remove your air filter, and see if it idles better?

Also, maybe you can check your fuel pressure. Check out youtube to see how

 

No lights are on. I haven't checked the air flow or fuel pressure yet. Doing that now.

 

Any codes?

 

Check electrical connections on ALL of your sensors.

Have you reset the PCM after changing various things?

Done your plenum yet?

Merged your two threads on this topic.

 

Can you explain PCM and plenum? Because I don't know what either of those are, so no, I haven't done them. Lol

 

PCM: Powertrain control module. In short, the computer that runs your truck. It sits over on the passenger side firewall, under the hood. To reset it, just disconnect the battery for 10 or 15 minutes.

Plenum: Your intake manifold is two pieces, the big aluminum casting, and a steel belly pan. The gasket likes to blow out, and you suck oil, have a HUGE vacuum leak, and performance suffers horribly. There is a sticky post at the top of this forum with WAY too much information on this topic.
