Well guys this is my first post on a forum ever about one of my builds. My latest build is this 2001 Dakota 3.9l 5spd manual. I was working in a salvage yard at the time and had 3 donor trucks to choose from. I bought this one for 300 dollars because of its immaculate condition given how long its sat. First thing i wanted to do was obviously put a v8 in it! I had assumed that the swap would be fairly simple since the trucks were so identical but later on in the build i discovered how different they really are. The main donor truck that i used for the motor was a 97 5.2l extended cab automatic. The others were also 5.2l but the motors were in questionable condition. The motor i decided to go with was the one that i could get running. So far the truck has been completed but ive run into one problem that has halted the build for a couple of months due to not having the time to work on it until now. I am currently stuck with a PCM issue. The original PCM is for a 3.9l 5spd 2001 model and the PCM i planned on using was from the 97 5.2l automatic. When using the 5.2l pcm the truck fires up no problem but dies immediately. Originally i thought it was a skim issue but this truck is not equipped with one. I decided to get it flashed and programmed for my 2001 but it still does the same thing. it took me a while to notice that there is a No Bus code so thats when i figured that the 97 pcm is just not going to work. So now im stuck because the 5.2l was not produced in 2001 and up on dakotas. I read somewhere that someone used a 2001 5.9l pcm to correct this but finding one at a decent price has been an issue so now im trying to research all of my options before putting down more money on a pcm than what i paid for on the truck lol Im sure someone out there has done this exact swap before and this PCM issue is the only thing that is stopping me! Btw with the v6 pcm on it will run but not on all 8, but with the v8 pcm from the 97 it fires up perfectly but dies immediately. Anyone have any wisdom of experience for me? This issue is the only thing i have left to finish on this truck! I would love to make a post of the entire build with plenty of pictures and info when im done but i dont want to post anything until i can resolve this issue! Help me out Dakota Gods!
