BAMF FORD
Hi, my name is Jeremy! I am new to this forum and am also new to diesel ford trucks. Not necessarily new to diesels though I am a Die-hard Volkswagen diesel fan and haven't much experience working on the old Ford's.
(sorry if some of this doesn't make sense, it applies to the diesel vw forum I am apart of and posted there because every ford forum i found was lousy.. until i found this awesome site!)
The truck in question is a 1987 F-350 with a 6.9 N/a IDI with 695k on the clock.
It's my gf's moms work truck. They have owned it for 8 years and have done nothing to it. And rightfully so it hasn't needed anything, until now. My gf's dad worked on it and kept it going good, but he recently passed on and now its up to me to keep this beast going because one day I hope for it to be mine Smile They don't run it all winter long because they claim it will never start, now this leads me to believe her father in his mechanical wisdom wasn't much of a diesel guy. I checked the resistance at the gp's and i think I got around 5.5, I thought the number was supposed to be like less than 1 or something? Also, I noticed that some of the gp's wires weren't even connected! Not only that but when you turn the key to activate the gp's the light goes off after 3-5 seconds! No wonder this thing could never start in the winter!!! It must still have decent compression to start the way it does..... ? I measured the voltage at the plugs as well and got a steady 8.4V Sad when i got it going for the first time this winter on Friday i hadn't found out about the gp's yet so i just used a battery charger set to 60A so i could crank the engine up to temperature. When i went to go out this morning to try it again (i was at their place for a few days) I thought to myself.. what about jumping the gp's? so i did that while i had my gf crank her, it fired up in about 10 seconds as opposed to Friday's 45-60 seconds. So it does seem that at least 7 of 8 (due to broken wire) are working.
Question being, where is the GP relay on these things? Also why would it only stay on for 3-5 seconds? It was about 5 degrees Celsius out today i would expect at least 10 seconds of gp's to attempt a start on an engine of such size and age.
I think that if I reconnect the broken GP, use Vince's guide to "pimping" to make sure they are getting as close to 12V at each plug, it will run a lot better. I mean they don't drive it in the winter anyway, but having the gp's actually work in the summer I'm sure will help prolong the life of everything.
The weird thing about this thing is, is that it was used before they got it, to haul a fifth wheel to B.C every year! for like 10 years. I am really surprised with how this truck runs.. Once it gets started it runs like a tank.
WOW this is a long post, I hope you liked reading my blabbering Laughing
What do you guys think? some cheap ways to maintain and keep this old girl going for a few more years?
Thanks a lot guys.
