   Starting problems

   My 260Z is having issues starting when left for a day or two, once i do get it going it will only be able to start itself for around 12-24 hours after being shut down. The starter seems to be going quite strong all the time, there is just no sign of the engine turning over. At first I thought the battery was on its way out but my multimeter showed it holding a good 12V even when the car was not starting. To confirm this I jump started the car this morning and even with 13.5V provided from the good car it still was struggling and took several attempts, although a bit more convincingly than on its own. The only way I can get it to start is to hook it up to a running good ca…

   Cost to rebuild?

   Hi all, Who's had an engine done recently? I'm trying to get a feel for a price to rebuild a stock L28. At the moment, I am staring at an invoice from ATK for $1,695 plus a $195 core. Back when I had my L24 rebuilt (in 1989), it cost me around $1,500. So, this might not be such a bad deal. What do you have into your engine rebuild? -- Mike

   Air Cleaner Snorkle

   I have a 76 280z that I am restoring. I've seen a snorkle attachment on later models that connect the air cleaner to the right side air vent above the hole where the engine harness passes through the radiator wall. Is this a part of the original 76 280z setup or is it only found on the 77-78 models?

    I have just aquired a '72 240Z with a 280Z L28 engine. Here is where it gets tricky.... new sparkplug wires, coil, and Optima battery. Still not cranking. It all started with me and my wife trying to jump the old battery. We got a quarter of a crank but that was it. Then the next step was to put the new battery in. NOW from the ignition, I don't even get a crank. I can hear the (I guess) starter relay clicking but nothing to the starter. Took the starter off, works as advertised. Put the starter back on, still nothing. Then back to the starter....I put the jumper cables on my other car and took the - and mounted it right to the - on the starter. Then taking the + side of …
