Bought 2001 Dodge Dakota 4x4 with 617 Diesel Transplant. Hot start issue, please help
Well I did it. I bought a 2001 Dodge Dakota extended cab with a 617 turbo diesel. Here's the risky part, it wouldn't start when I bought it. PO said the injection pump was out and that was it. Included in the price was a working used one. The conversion looked like it was quite well done so it didn't take me long to buy and have it on a tow truck.
Got to my mechanics shop and the new IP was put in, nothing... Ugh the new (used) pump was a dud. I bought a rebuilt one and we got it in yesterday and the truck came to life! Engine sounds great when it runs. Was blowing heck of a smoke though, I'm sure that will go away it had been sitting for months. Now the problem. Once it get's warm it doesn't want to start again. And when it's running it gets too hot and shuts off. We figured out the electric fan (no mechanical one there) wasn't working. So I have ordered a thermostat wiring control for the fan. We did jump it but still couldn't get the engine running again until long time and it was cool I'm going to replace the glow plug controller with the updated one as there was something wrong with the old one and we had the jump the plugs too. Anyone have any ideas on why the engine runs great but won't start when really hot? I'm going to replace all the rubber fuel lines next in case there is air leaking in when warm... Thanks for any help! The truck is at my mechanics shop, when it's fixed I'll get pics taken and upload!

So:
It starts easy when cold. It runs fine. It will not restart when hot. The next time it will not start when hot: cool down the IP by pouring a bucket of water over it. Report back if that makes it start or not.

Hows that TD working out. I remember a few years ago you got the driveshaft rebalanced and all was well. What kind of millage did you wind up getting? As I remember I get around 34 on road trips with my 5 speed TD. Good luck with the PU, I like those Dakotas.

I was with the mechanic while we were getting the Dakota started for the first time. It was being a PITA to get the fuel from the tank, we jumped the in tank pump that was original on the dakota. We're not sure if that should run, we think that since we got all the system bled the Mercededs fuel pump could handle from there on.
Ok will try the cold buck of water IP trick and let you know. I won't be back to his shop until Monday to try it. Oh the wagon has been great! I hit 34mpg on the freeway once. Love driving it now...so awesome having that 5 speed!

I've been reading a lot and I think we are having fuel/air leak problems. I ordered all new hoses to replace fuel/injector lines.
I am wondering more if the tank might have junk in it, we weren't getting good fuel flow until we turned on the in tank pump. I don't think we need to run that pump though, but it wasn't moving at all until we power it up for a minute and shut it off.

drop the tank and get rid of that pump. the best thing you can do is exactly duplicate the benz fuel system, no restrictions, nothing that could impact diagnosis for engine issues.
there have been numerous examples of people trying to work around and around an in tank fuel pump they just dont want to remove, and ultimately it was some characteristic of that pump that caused all their problems. i say run the motor off a pop bottle in the engine compartment, if it works, get rid of that fuel pump. i have personally seen an example where an in tank pump was connected to the return line at the top of the tank with a poppet valve for some gasoline reason. what would happen was the lift pump on the diesel could pull this poppet valve open and draw air. result was at half a tank the vehicle would run out of fuel, as the return line was much higher. sounds like a cool truck, post some pics! i wonder how the 617 does moving that size truck and 4x4 system around, should be fun on the first test drive

Thanks for the response JB3! I was just going to post because my mechanic called me and said he'd been thinking about it. He really thinks we need to change the fuel outlet from the tank getting rid of the in tank pump just as you said. The dakota tank has an outlet at the top that the pump draws it in through vs MB tank where outlet is at bottom and gravity flows the fuel through. I think we'll drop the tank and put a new outlet on. My hourly bill must be rising thankfully he's quite a nice guy and really wants to see this thing run.

Edit: "As per post #9, and reading the link, Iam all wet in what I wrote here. I guess I should say pouring hot or cold water on the IP will greatly improve it`s performance." We are packing for a move, so I can`t quote the source I read it from, my manuals are packed away until we unpack in Oct/Nov. Charlie

Well I think my IP is OK because I spent a lot of $ on a professionally rebuilt one. I believe my issues now are because the PO was using the stock dakota tank setup.
I've been reading about a lot of air getting into the fuel that causes power loss and such. I want to make the tank draw fuel from the bottom and not the top like it does now. Anyone have ideas about how to alter the dakota tank to do so? I am trying to find a bolt on fuel tank outlet I can put on there.

I'll second that move! Get rid of that fuel tank/ fuel pump and go gravity. Nothing better, nothing more simple.

Why don't you try and run the engine using the soda bottle? It's easy to do and is almost free. If it runs on the bottle, perhaps your issue is the fuel tank. It could also be a clogged fuel cap or tank vent causing a vapor lock. Start with the simple cheap fixes unless you know the parts are defective. If the truck will not start or run on the soda bottle, it's probably related to the filter/ fuel pump/ hose clamp or air leak. Good Luck

Finally Pics and a vid in this post. I have Good and Bad news... Good news is truck is running! I think we were dealing with fuel/air leaks (maybe a pocket in that new IP too). You can see a video of the truck running here:
2001 Dodge Dakota with Mercedes 617 Turbo Diesel First Run - YouTube Bad news is I took out for an extended drive today and there clearly are some issues. First thing you'll notice is a lot of smoke. I am thinking this is because it sat for 2 months...? After driving a bit it cleared up some, but is WAY more smoky than my 300TD (which barely smokes at all). Any ideas how to clear up smoke? Or just drive a tank through it maybe? The big bad news is lack of power. On the freeway it did 55 mph and didn't want to do more. I am thinking this has to do with lack of fuel. I know what a 617 can do and it just seemed like something is wrong, not that I was maxing the engine. I brought the truck back to the mechanic. Our plan is for him to take out the in tank Dakota pump (not being used now) and install an inline fuel pump with metal hose drawing up from the bottom of the tank. This should ensure there is no fuel starvation, the idea is from others who have converted Dakotas. Any other ideas?

Do you know how it is adapted to the 42/44/46RE whatever is in there, and how the electronic transmission is controlling the trans without having any input from the engine?
Though it looks like it may be a stick. I've got a Dakota and a spare 617. I've had some thoughts...
