1997 Dodge Ram 2500 5.9 Gas hates to cold start NEED HELP

This started a couple of days ago. When i park my truck for a while like 4 or more hours when i got back out to restart it it won't start. It will just sit there cranking. If I start feathering the gas pedal it will get some life and start to try and fire. After about 2 minutes of doing that, It will finally start up but starts at really really low RPM and I have to keep it floored til the RPM's come up. Once the truck is running it runs fine. And I can park it run into a store and come back out and it will start up just fine. But mainly wont start after it sits out all night or while it sits while I'm at work. Any help would be greatly appreciated. Thank you so much.

Sounds kind of like a fuel pump issue... First make sure your fuel lines aren't leaking (crappy mileage would also be a good indication of that one).

Once you're sure that's not the issue, have someone sit inside the truck and turn the key to ON, but don't start it. Stand out by your gas tank and listen for a whirring sound. Then have your lovely assistant start the motor and you keep listening... if you don't here anything, something's wrong.

First check the fuel pump fuse, then your fuel pump, the pump's relay, and the ASD relay. If ya need help checking those things, lemme know and I'll give you some more help.

okay thanks for the help. Any other suggestions would be greatly helpful to. Another thing i didnt mention earlier is when it does finally fire up its smoke pretty bad but only for a minute or 2 until the engine starts to warm up then no smoke what so ever.

i have the same problem but i have a block heater on mine. dont ask why it has one but it dose so i just plug it in. but my guess was the hard starting has to do with my blown plenum gasket.

If you're getting white smoke, it means you have water or anti-freeze leaking into cylinders from somewhere (probably the head gasket). If you have blue smoke in there, there could be oil leaking in too.

Check your oil to see if there's any anti-freeze/water contaminating it. If there is, it'll have a milky look to it. Blown head gaskets, cracked heads, and bad intake manifold gaskets can cause this. Often times overheating will make those parts fail... has the truck overheated ever?

A good way to check for oil leaking into the cylinders is by looking at your spark plugs. If they're black and full of oil, you know you have a leak. I don't know Magnum engines well enough to recommend any specific seals or anything to check, but I'm sure some searches around here might reveal some info for ya.

EDIT: Mine actually starts hard too and I'm beginning to think the cause of mine is also the blown plenum gasket. Seems to me like the pressure inside the kegger intake is taking longer to build up because of the blown gasket and that's making it take longer to start.

Badass, to check for a blown plenum, take your airbox off and open up the blades on your throttle body. Shine a flashlight down in the holes and if you see oil sitting in there, your plenum gasket is blown. Here's what you want to replace it:

It could be one or more injectors dumping fuel into the intake after you shut it off. If it is black smoke, that would be my guess. Next time, hold the throttle wide open and crank it (dont feather it). The computer thinks you have somehow flooded it and wont fire the injectors until you let off the gas. This is a throw-back to the carb days.

Okay well the smoke is white with a hint of blue to it. I checked the oil and it looks fine so discoloration or change in texture. Then i pulled 3 of the spark plugs to check them out and they were dirty, but no oil build up on them. Then i removed the air box and opened the throttle plates and shined a flash light down and saw a small small puddle of oil and the rest of it was just damp but could tell what it was damp/wet with. And the smoke still doesnt make sense to me cause its only for a couple of minutes. All i can think of is its just all the unburned gas or something from me cranking on it for so long.

Sounds like the plenum gasket.

I've seen your issue before, and it was a leaky injector. When it sits long enough, the leaky injector(s) floods your engine.

Wouldn't it be smoking black if that injector were leaking a bunch of fuel into the cylinder though? It definitely seems weird that you're smoking and not seeing any of the other symptoms though...
