  1. Jeeze! Smog stuff needed to sell a 1978 truck in California. Just another example of legislators making rules about stuff they know nothing about. Your tax dollars at work. Fortunately, I'm in Oregon. Yay!
  2. I appreciate this forum so much! Three replies in less than an hour. A few details: Yes, original family ownership. Was my Dad's, passed, through the trust, down to me. When I took it over in 2010, it had 28K original miles. Dad liked power steering, being he was in his 80s, and this little truck didn't have it. He mostly used it to drive junk to the dump, three or four times a year. I've put on the rest of the miles. Has a new carb as the old one rotted out from ethanol tainted gas. New muffler as the old one exploded from a backfire, because of gas leaking through the carb. The shop that installed the new carb ripped out all the old, useless, emissions control hardware. The block and pistons are original. Tranny is in good shape. New radiator as the old one gave up. Every other replaceable part has been replaced (starter, coil, alternator, hoses, plugs, pumps, reservoirs, etc.), Paint is the old industrial orange with 42 years of regular age. Windshield has some wear from many, many wipers and a fair amount of gravel thrown on it over the years. The driver's seat upholstery is wearing out and the seat inclination ratchet needs work, broken tooth or two. Dad installed a CB radio in the forward part of the console and some of the trim is showing it's age. No injuries or MVAs. It's been a faithful part of the family since new. Probably what you would refer to as an enthusiasts truck. Whatever that means. It's far from cherry but it's still got a lot of solid miles left in it. When it's not raining and grey outside, as it is now, I will get some pictures. Thank you everyone. Daddio
  3. Hello fellow Ratsuns, I have a '78 King Cab 620 with around 80k miles, it's in fair shape and is part of a Family Trust Estate. Eventually, we will need to find the value of the truck such that it can be included in the value of the estate. I have been checking, as best I can, to find the value. It ranges from $500 to that being just the down payment or deposit. I know there is a market for this little truck because soooo many guys have asked me if I want to sell it. How do I go about getting an accurate idea of it's value? Greatly appreciate your insight, Daddio.
  4. King Rat, appreciate the checklist. There are several things on that list I have not tried. Wasn't looking for a short then. I'll print it off and run though them next time it acts up and report back on what I find. At this time it starts right up. 😒 Can't trust it. I bench tested the ignition switch last time it wouldn't run. It seemed fine at the time. However, it is a stock switch so I couldn't blame it if it did have issues. Much appreciated.
  5. Bought a new pick up coil for the distributor. Thought that might the problem. Nope. Installed a new ignition unit (under the glove box), both less than six months old. Old one worked when I tested it after it came home from the shop. Yep, been there, done that.
  6. King Rat and L motor God, Thank you both for your input. Obviously, my question needs to be re-framed. First, just a tad bit of history. This truck has been in the family since new off the lot. I have had it personally for the last 10 years. There isn't much about this rig that I haven't had apart, replaced, repaired or my hands on. New radiator, new carb, new muffler, new this, new that.I think the only original part of the engine is the block. I do most of the service myself, except when I DON'T have the tools or diagnostic equipment to work on it. I don't replace tires on wheels and I prefer to have the brakes done at the shop. That's why it was so frustrating to have to take it to the shop for this problem. After a month of playing with it, it had me stumped. Yes, I am aware that it is either spark or fuel. Fuel does not seem to be the problem. Mechanical fuel pump works, clean fuel filter, gas showing up in the carb. So yes, spark. Starts right up, when it wants too. That eliminates the starter, battery, alternator, coil, spark plug wires, fuse-able link, distributor electronic ignition , the electronic ignition module, ignition switch, ignition relay and fuse box. Now, could one of these go intermittently bad? Sure!!! Symptom: running just fine and instantly dies. Will restart after 5 to 15 minutes. When dead, it has no spark. Minutes later, it has spark. This happens after it's just started, it happens when it completely warmed up. There is no pattern. There is no sputter, shudder or notice when it will die. New coil doesn't make any difference. Coil tests fine. Everything that can be bench tested has been. One of the parts replaced was an OEM electronic ignition module. Found an old stock, unused unit. I bought it for the shop (at less than half the price they were going to charge me) and had them install it along with some other work being done. They also replaced the coil while in the process. I asked for the old parts. When I got home, just for fun, I switched out the new units for the old coil and the old EIM and sure enough, it started right up with the "bad" units. I put the new units back in and kept the old ones as back-up parts. This is one of the best shops in the area. The shop may be okay but the mechanic may have issues. Probably has a big boat, two ex-wives, hot girlfriend, horses and a drug habit. Dirty connection? Loose wire? Temperature sensitive connection? Poltergeist? I'm hoping someone else has had a similar problem and found a solution. This problem probably isn't exclusive to this brave little truck. Seems like every other time I'm out with it, someone asks me if I want to sell it. Holds it's value for being 42. Thanks for the help. Daddio.
  7. Hello Datsun fans. I have a total mystery on my hands. My '78 620 King Cab has an electrical glitch that causes it to instantly quit when sitting at idle or in park. Ongoing problem. Worked on it for two weeks the first time and a month the second time without coming to a solution. Had it towed to the shop both times. Last time it was $800 with a fist full of new parts. Two months later, it's doing it again. Only this time, I'm able to restart it after 15 minutes. Runs perfectly, maybe for 10 minutes or maybe for several hours, then does it again. Very frustrating. Every component of the electrical system has been either traced, checked multiple times or the parts replaced. If it were a component, it would have showed up and been replaced by now. I honestly don't think the shop figured it out, they may have just gotten lucky. This particular issue has accumulated almost $1500 in parts and labor over the last year. All the obvious things have been done. Looking for something that isn't obvious. Perhaps you have had a similar problem. I'd love to hear about how you solved the mystery.
  8. RedStar620, did you ever determine exactly what the problem was?
