1996 6.5td idle problems
first off hello from delaware. i have been working on gas motors/trucks now for a little time but this would be the first diesel i have touched. but anyway me and my buddy just picked up a "work" truck in its previous life it was a plow truck. but the body isnt that bad off, shes been parked for the past couple years. then my buddy who owns a welding shop needed another work truck. he has his 04 chevy v10 and my 94 c1500 4.3 its ok for small runs but if we need to haul anything with weight we have to use his 04 or my 79 k20. but my k20 is limited due to 6" lift and 40s. and his 04 doesnt get good mpgs with the box on the back and welder and tools so we need/wanted a diesel was planing on getting a cummins and dropping it into a 89 3+3 but this deal cam along and we picked up this 96. but the problem is/are the glow plugs seam to be messed up. i dont know the full details but my buddy looked at them and said the harness seams to be melted or something. so anyway we tried to start it to get her loaded on the trailer. took about 10-15 seconds of cranking to get her to fire up. once she did she screamed to 2k then back down to about 1k then a couple seconds continued this cycle. during this run she would blow black smoke then white/maybe gray smoke this was alternating with the rpms. dont recall which smoke went with which rpms but it was changing. after 10 seconds of this we shut her down. started to look for other problems. both of us can work on any gas motor fine he has more experience than me in diesels but its not much. so while we where cranking on her i recalled not hearing the lift pump with the key on. so we checked it no power to it. replaced it with one we had and ran a jumper wire to the battery. bled the line and started to crank still same results. now i know the body looks ok with rust but the bolts seam to be hurting, so could this be a ground problem? from what im reading it seams like IP. the pmd is relocated so its not stock but it could be bad. need to find a working one to test her with. but till i find one im looking for other things that could be a problem. i dont know but i think my buddy said the throttle light was on, and when it was doing its thing there was little to no throttle response. now on a side note we had to start her by jumping the starter ( it was getting power but thats it) the guys father came out and told us the PO knew the starter was bad but he didnt want to put any more money into her. he did act surprised when we did get her started and she ran like crap. so till i get a response here i will continue to search for similar problems.
quick question, how important is it that the batteries be matching?
