Ok, this may be Ram 101 for most of you, but I'm a greenhorn- (no pun intended). I have a 93' 350 with 186k miles. I love the thing. I tell it to do something, and it has the power to do it. Pull Simba!...and it pulls. Anyway, I have a problem keeping it running. I'm in Louisiana where it isn't really cold and you can buy real estate by the gallon. When I first crank it up, it will run good for about a minute and then it sounds like it starts to bog down like it's starving for fuel. Then it just dies. I could try cranking it till the battery dies and it will not start up. If I break all the injectors, bleed them, tighten em' back up. It will crank, fire over slowly on a few cylinders, blow white smoke, and eventually, as it gets hot, run good and stay running. The smoke goes away. Drive it all day with no problem restarting. I then let it sit over night and it will do the same exact thing the next morning. Now if I plug in the block heater, it won't do it. It will run good and won't kill. And really, it isn't cold enough here for temperature to be the problem. Plus it looks wet under the injection pump, on the bottom transmission side. And I think I saw a drip from under the pump once after I popped the hood to do my bleeding ritual. I don't forget to plug in the heater anymore. Does anyone know what this can be??? Any help would be great, thanks.

 

Start by replacing the fuel filter,and put some additive in the tank.Cheap,easy and won't hurt a thing if its something else.

 

I actually did replace the filter and put some additive and nothing changed. Thanks though!

 

There have been some posts, and warnings from fuel manufacturers, about possible seal leaks on older model diesel engines with the introduction of ULSD. I would look for the simple things first before I jumped into a pump.

 

What are the simpler things? And the pump must be leaking because I went out and watched it make a drip when the wife was turning it over.
