I got the 92 running

[JDKammin]

To give a little history, I bought this 92 truck with a broken flexplate. I could not start the truck because of a dead battery and broken flexplate. I did find the cheapest place for Cummins parts is to bypass the Dodge dealer and go directly to Cummins. Thanks to this post for the info. Anyways, with the flexplate on, I was getting ready to bolt up the transmission and noticed that one locating dowel was missing. Could this be the problems to the previous problems of the flexplate breaking? This is not the reason for the post. I decided to get the engine running before installing the transmission and transfer case. After charging the battery, I turned the key and the truck started faster than I could get my hand off of the ignition switch. I idles really nice and carries good oil pressure and no knocks or odd noises. I pushed on the throttle and about 1/3 throttle, the engine will start missing and start blowing white smoke out the exhaust and will then throw a check engine light. My thoughts is a bad injector, which is shaking the engine bad enough to activate the knock sensor, if these engines have one. What are your thoughts? Maybe after getting the truck back together and driving it around, the injector may clear up. Wishful thinking? Thanks.

Sorry to say it, but I just bought a 91. 5 with EXACTLY the same symptoms. I first swapped out the injectors, no change. It was something inside the injection pump. I swapped in a good injection pump and problem solved. Sure maybe once it's back together something hopefully will clear up. Start looking for a reman pump. I'd give my money to a reputable Bosch/fuel injection shop before a local or fly by night $300 outfit.

Hopefully, I will get the transmission and transfer case in today. I can then drive it around and see if it gets any better. Did your check engine light come on also? Did you get a pump set up to factory specs or with more fuel? Thanks.
