i'm buying a 1986 tomarrow with the 6.9 diesel that doesnt run, he said that it wouldn't start unless he poured some diesel fuel in the intake then it would start and stay running and that worked for him for a while now it wont start at all what do you guys think? im going to test the gps tommarow and check fuel pressure from the mechanical pump what else should i try he said it ran perfect when running.
I think I'd steer clear of that one. My Crap Detector is going off. Diesel engines fire off when fuel is sprayed (HIGH pressure) into the cylinder during the compression stroke. Liquid diesel poured into the intake would be about as effective as lemonade.

Depends on the pricing and condition. You can put quite a bit into a $500 truck with four wheel drive and a decent body and be in good shape. You can't do well with a $2500 rust bucket that needs tires and brakes with two wheel drive and a bad transmission that you cannot diagnose because it does not run.

Pouring Diesel or any liquid in the intake is a great way to hydro-lock the engine and bend a rod.
The guy with the truck is a BS artist.

Yeah i thought diesel in the intake wouldnt do anything so i asked him when i was there if he was using starting fluid he said he was didnt really bother me too bad because i knew that if he had to use that the glowplugs were probley burnt, so i brought a battery to try to turn the engine over and the sender by the thermostat housing started to smoke so i unplugged it, then turned it over it barely wanted to move it had been sitting for a year, so he was asking 900 i paid 600 its a 1986 f-250 2 wheel drive in great shape for the year and only 157,000 on it and 5000 miles on new trans and good tires, so when i got it home i put a couple used batteries in it and hooked it up to the charger still not turning fast enough so i went and bought 2 850ca and 1000cca batteries and installed them still slow and no firing, next day i went and bought a injection pump from a junkyard installed it still nothing, so i remembered on my 6.9 when it turned slow the starter was cooked so i took the new one off my other 6.9 and put it on my new one sprayed a tiny bit off either and she fired right up runs very smooth and quiet and more get up and go than i expected, so i bought new gps which the old ones were all burnt 2 were stuck but i got them out without breaking tips but what else to expect when there champions, bought a couple new parts to get it on the road, now i go outside wait for the gps and it fires right up, the only thing is the high idle isnt getting power and that sender by the thermostat housing was smoking i forgot what that was. but other wise a real good truck that i could easily triple my money on but i love the old 6.9s and its staying with me, i'll get some pics up soon. Now i think it was the gps and starter all along my other injection pumps still good, its nice to have a extra one and i only paid 79.00 for the one thats on it and a air cleaner assembly.
I think u did alright and got a good deal on it all these other guys where doubting it saying it was all bs but hell I dont know the guy that sold it to u but maybe he dont know jack about diesels. But u took it upon yourself to check it out and got the old girl runnin. Sometimes its good to just tackle an old project like that cause they can come out smelling like a rose. I would of done the same thing u did, even if it wouldn't of worked out for 600 bucks u could of got ur money back it parts, I say u made the right move.

thanks sanmanf250, thats about right he didnt know anything about diesels, but you can usally read people when you go to buy something from them. So he seemed honest and i took his word for it that it ran great before it wouldn't start and he was right it runs great!
