hey everyone! I am new to owneing a diesel and i have a few question that i need help with. The frist thing is i have misfire and need to be pointed in the right direction of how to check and rule things out. The next thing is the exhaust mainifold looks to be leaking not sure tho. so i want to replace the turbo gasget and mainifold i seen that the mainifold in known for wraping, so what kinda prices am i looking at for those? Would these leaks cause my turbo not to spool fast enought and at the right boost? what is the stock boost setting for these truck and what can they push? i also have a trans problem where its starting out in 2nd gear but we have that diaged n will b fixing soon. this is going to be my daily driver and want the best out of her. oooo and the truck is a 1999 dodge dually diesel 24v. tanks again for the help

tell us more about the misfire

the exhaust manifolds cracking is a very common problem look to spend 400-500 for an aftermarket 3 piece or around 250 for an aftermarket single piece replacment. and yes if its cracked bad enough it could hinder the turbos performance

stock boost would be 15-20psi

ok the misfire dosent really seem to show untill the truck is warmed up mabye like 10-15 of idling maybe less.

no check engine lights?

no CEL i scanned and got nothing. used solus pro scanner. will try again tomorrow. i have yet to even take the truck off my shopd lot so i havent been driving it to see if the light comes on.

ok finally today I was able to look at the truck at work today. I had a furl pressure of 11psi at idle (almost on empty). I loosened the injector nut on the number one cylinder wen i first started the truck and fuel came out, and then did the rest. I waited for the truck to warm up until i got the misfire and opened the #1 again and new fuel came out then i pushed on the line and fuel would come out. So is it possible that the injector is messed up or not?

Does it misfire only when idling or when driving too?

Miles on truck?

Stock lift pump?

I miss could be a injector or a updated injection pump. Most of the enhance injection pumps will cause a miss at idle but not when it is under load.

miles-319150, as far as i know everything looks to be stock looks like injection pump was painted. I have never worked on a diesel before and dont really know where to go or start. I do work on cars so know were to start (some what). How would i tell if it is a newer injection pump?

Injectors do wear out.... strange you have no codes, that is normally the best lead you'll get, it could be so many things. Personally, I think 11 PSI at idle is a little low... I get scared when I see 12 at WOT :scare2:

Probably has something to do with your fuel system in 1 way or another.

I like the miles on the truck..:tu:

If they are the stock (99) injectors there a little wore out.

The injection pump painted maybe a indication that it was replaced.

Do you plan on keeping the truck?

The misfire only seems to be after she warms up at idle. Thanks on the mile amazing she is still running (some what) is there anywhere I can find a number to see if it is a stock injection pump or newer? Yes I plan on keeping her for awhile :D

if it is a black, oem bosch unit it should have a big "REMAN" sticker on it, right on top. There is a serial number on the side, I suppose you could try calling bosch with that number, but I don't think that will even matter, get a raptor or airdog pusher pump ASAP :scare2: lots of great vendors here on db you can get a price from, raise that idle pressure to 18, and just pray the vp holds out

If the pump is brown its a cummins reman unit, when it starts to miss, open each injection line one at a time until you find the one that doesn't make it worse.

If there is no aftermarket lift pump on the truck, you will want to get one asap, with that mileage I would say its safe to buy a set of injectors, do a valve adjustment while your at it. did you get any kind of service history with the truck?

I will try tomorrow and see if i can scratch some paint off n see the color. i let it run the other day and opened the line to see witch got wrose. The number 1 injection didnt make any differance wen opened i completely took the nut out and nothing, however when i would push on the line slitly fuel would come out. Is there a stock lift pump ont these truck or no? what is the semi-best to go with on a budget? how dose it work alomst like a fuel pump being in the tank?

Unlikely you have a pump in the tank, that was the "recall" pump, that somebody would have bought from dodge. It is on the side of the engine block kind of hidden behind the fuel filter canister. the "pusher" pumps we all talk about bolt to the frame. I'd say Raptor 100 if you're on a budget, or 150 if you plan on making hp.

so know by putting this lift pump on it would bypass and cut out the stock one completely. the othr i had forgotten to say the other day is wen i cycled the key i had no pressure on my MAC fuel pressure gauge. then when i started the turck i got 11psi.

ok so today i put a stock lift pump in (thats really all i could afford at this time). when i cycled the key still didnt get any pressure reading, not sure how that really works on a diesel. My running PSI was about 13-14 and WOT 11psi. It seem that i still have a bit of a misfire i sat idleing in my drive way for about 15 mins and seemed like it wanted to maybe idle right. I think tomorrow i will try opening the injector nuts and seeing if i can bleed them out more and see if that make a diff.

i had the same problem its ur injectors i replaced mine and it runs like a top

Ok thats alot will do as soon as i get the cash:argh:...
