So, this is my first real post as I have been reading all the posts that may pertain to my issues. There is so much great information on here.
First I have a 93 Chevy 6.5 TD, K3500, single rear wheels, extended cab, long box, w/gooseneck hitch. (Love the gooseneck nothing pulls better.) 234,000 miles. I have had this truck for about 6 yrs., with only a few problems.
This last winter while using it to pull the mini excavator around, it began to show problems. It would start fine, I plug it in religiously, after about 5-10 min. at idle it would sputter and miss. Sometimes I could give it just a little higher idle and it would come out of it, sometimes not. I could crank it over and it would take just a little to pop off again like it got a little air. This would happen sometimes 3-4 times in a row, the same way. Once I get it to the open road and get moving, I kind of baby it a little, it would come out of it and be fine the whole rest of the day, even letting it set while at work for 8 hrs. I have had the tank down and cleaned, all new parts there, pick up hose, sending unit, all that, the old ones snapped off when i tried to remove them. I did the new lift pump, and new factory fuel line to the filter, new filter several times.
That stuff I can live with, gets frustrating though, but last week I started it and it acted like it was loading up with fuel. Started fine and idled fine for 8 min. and I tried to move it. I made it about 60 ft. and it started acting up again. This time though it was puffing lots of white smoke that smelled like lighter fluid on a BBQ when someone puts the lid on and snuffs the fire out before the fluid is all burnt up. Of course I was 3 miles from nowhere, with my partner in crime and no one else to call. So I checked under the hood (like I could tell anything from looking) and with out tools, I was forced to try to start it again. It smoked a lot, like a 007 smoke screen. It wasn't making any noises abnormal to the diesel except for a little miss. I have acquired a compression tester, and am planning on replacing the injectors and pump if all the cylinders are up to snuff.
I am looking for a word of encouragement in hopes that I am headed in the right direction. What is a good psi or is it OK if they are just all close to the same.
Any ideas on these issues, are they related.
BTW at first with the "air" problem it was helped by leaving the fuel cap loose.

 

ok it can be few things first all how many miles on truck where is the PMD mounted at

 

uhm??? I didn't think 93 had a pdm and 234,000 miles. I had a new tranny installed this fall.

 

I wasn't meaning to be rude. If there is a pdm I haven't touched it. The tranny doesn't have anything to do with it, but I thought I would add for the info.
I had an exhaust put on. I was in a pinch and needed to get it on due to work out of town and the locals didn't like the noise. Anyway they installed a new factory down pipe, and then the 2 3/4" back to a muffler which they stuck on, it had 2 3/4" inlet and came out 2", didn't understand the thought in this. I think they thought I was just an out of towner they could rip off. I said something about it and they said they could put another on next week, well I got transferred. I cut drilled holes in the back of it to let it breath some. It all rusted off in less than a year good stuff
Anyway thanks for any info.

 

So, I thought you guys were a little better at getting to questions on this site than other places. I am a little disappointed at the lack of input. Am I not in the right place? What happened to all the good ideas and pointers? Anyway, I tried to test the compression and pegged the gauge. 300 psi. didn't cut it, Oriellys' supper staff said it would work, and me trying to save a couple days not waiting on shipping thought I would try it. Luckily they took it back without question when I told them it wasn't high enough. So now I am supposed to get the new compression tester delivered today.
When I started the truck up to pull it into the shop though it didn't act up at all. Would it matter if it is parked on level ground or not as to how it would react? It sat about the same amount of time each time I have been using it lately. This time it was on level ground and sat for about 4 days. When I started it I had to tap on the glow plug relay it sticks (yes I am replacing it too) It cycled once I tried it and it popped right off without issue little rough still. I was able to get into the garage without it stalling, or smoking like crazy. I only let it idle for about 1 min.
Does an injector act up intermittently?

 

I have a 95 k1500 4x4 with a 6.5 turbo diese it has a little over 79,000 miles on it..The problem im having with it is it will run for 10 seconds and then die ..Have replaced the fuel filter and lift pump and also the sending unit in the tank ..It had DTC 54 internal fault in pcm so i replaced the pcm and problem is still there ..Hope some one has some kinda of an idea ..Thanks for any kinda ideas

 

have you done OPS or maybe bad PMD
