I have the same setup with exactly the same problem with my 260z. I just assumed it was God telling me to slow down.

The same thing happened to me. I was starting the car when the key just stopped after about a quarter turn. I couldn't turn it back to the off position or forward. I called a locksmith because I was stuck in a parking lot miles from home. He told me to tap the end of the key really solid, but not too hard, three of four times -- like I was driving a nail into a wall. He also cautioned that I should make sure I hit it square and not at an angle. It worked. the tumblers had jammed up inside and banging knocked them back in place. I gave it a blast of WD 40 when I got home. It's been about six months and I've not had any problems since. I make sure I keep it lubricated with a few drops of oil on the key now and then.

Check out my gallery. I love my z, so I haven't totally decided to sell. However, I need the money for my kid's college. So maybe in a couple of months I'll be ready. As far as price; I just don't know yet. Make me an offer.

Here are some other interesting points about the 260. Although the 240 was produced from 1970 to 1973; and the 260 was produced only in 1974 the number of vehicles manufactured by Nissan is about equal for both models. The Z car was growing in popularity over the four years the 240 was produced and peaked in 1974. This is confirmed by the number of cars produced per year. I wish I had the numbers to quote; I'm going by memory. As with any car, minor improvements are made throughout the production as the manufacturer finds out what works and what doesn't with any given design. In my opinion the quality of the product also peaked in 1974. Nissan figured out how to do it right by then. After 1974 the quality and "specialness" of the Z car declined. Just look at any 280z on a used car lot and you can see there is no comparison to the 240 or the 260. Another fact about the 260 is that they are heavier than the 240. The two major reason are: the metal on the 260 is thicker than the metal on the 240, and the engine is bigger. Again I don't have the exact numbers to quote. Some people like the lightness of the 240, but I think the combination of greater horsepower on the 260 and the stiffer unibody created by the thicker metal make a better automobile. One reason there are more 260s is, I think, they didn't rust out as quickly as the 240s. So, lets review why the 260 is better IMHO: 1.) You get the styling of the 240 (especially in what is refered to the early 260s with the "thin bumbers") 2.) Most 260s have already had the major flaw removed: the evil-government-mandated emission control carbs. 3.) Larger, more horsepower engine. 4.) Stiffer, thicker unibody with more rust-through protection. 5.) Lower price because of marketplace realities. One other difference: the 260 introduced the electronic ignition module. I think this is superior to the mechanical points and condensers of the 240. Face it, 1974 was the peak of automotive engineering genius. These are just my opinions, and I'm also thinking of selling my 260.

Wouldn't it be great if it was just a hose. So, how do you do a pressure test? Is it a matter of waiting for the car to heat up, or is there another way to put pressure on the system? Anyway, I will get in there and check it out. I do appreciate the help. Thanks.

Clue number one: windows fogged when the car heated up. Clue number two: I could smell coolant. Clue number three: I found a small puddle on the passenger side floorboard. Does this sound like a leak in the heater core? Is this a major or an easy one? Anyone had experience?

I installed the Crane Fireball from MSA. Works great. Can't tell if there is an improvement on performance of the engine overall, but it seems to run smooth and has good ecceleration. I'm very happy to be up and running again.

I've decided to go with the MSA Crane "Fireball" electronic ignition kit. It replaces both the module and the pick-up coil. And its a whole lot cheaper than replacing both stock. I will post an update when I'm done. Marshall

Thanks CoastGuardZ for taking the time to do the test. It amazes me that you would not only take the time to give your advice, but also go the extra mile. I really appreciate it. Anyway. I think my coil is good based on a good resistance reading and getting some spark. I think the spark was weak because my battery is getting low. I agree with smg1404 that the problem is in either the pick-up coil or the module. Probably the module since its the most expensive to replace stock. Again thanks guys.

I think the reason they couldn't test it is because they did not know what the output should be. They had no specs on the Mallory. I'm not really sure why the previous owner replaced the coil with a higher output "performance" coil. Its still running through the ballast, which I thought reduced the voltage so it wouldn't burn up the points. So whats the point? Why not stay with the original? I'm wondering if it would make any difference to go back to the standard coil. Also, this didn't seem relevant at first, but I had a leak in my radiator and was not aware until it overheated. I had replaced the radiator just prior to the problem of not cranking. I'm wondering if I've burned up the water temp. switch. Haynes says that its a spark timing control system on cars with automatic transmission. I have a manual trans., so I don't know. Maybe I should just start replacing parts until it runs. I think thats cheaper than having it towed to a mechanic and paying them to figure it out. Or maybe this would be a good time to go completely to an electronic ignition setup. So many options.
