I've had my '73 240z for a couple of years and its always run pretty decent, but it overheats in city driving. Last fall I was driving and hit some rush hour and it got pretty hot (about 3/4 of the gauge). After a while I got out of traffic and it started to cool down some, but about a mile from my house it started running really rough and 1/4 mile from my house it died completely. I coasted downhill to my house and pushed it into the garage. It wouldn't start, but I was so tired of the overheating I took the radiator out and got it rodded out. I also installed a fan shroud. After I got all that put back together, I've been trying to get it started, and it just won't start. I took the coil wire off of the distributor and held it next to the valve cover while my daughter cranked the starter. I expected a spark to jump across to the valve cover, but there was no spark. Doesn't that automatically mean the coil is bad. When it WAS running, it would hesitate when it hit 3500-4000 rpm. Doesn't that indicate a bad coil, too? I went and got a "IC70" coil from NAPA today. That's what their computer spit out as a replacement. Its a little skinnier than the old coil, but I tried it anyway. I don't get the coil-to-valve cover spark with this new coil either! What else can I try?

I have had my z for a couple of months (1976 280z) had some trouble with the ignition relay at first (accessories did not work) but got them working in the end. Started driving it 2 weeks ago no problems everything worked fine. Then last week I went to start it and it had no spark so after messing with the ignition relay and coil for a bit I found one of the fuseable links was bad (the one that goes to the lights, whippers and washer motor controls.) I replaced it hooked up every thing tured the key, and nothing worked then I heard a relay click and a fizz frying type sound comming from the passanger side didnt smell any thing. I took out the igniton relay and took it apart and all the wiring harness conectors. Checked the relay and filed the contacts and hooked it back up and still nothing. If I turn the lights on the voltage gauge pegs below 12 volts and the lights dont turn on the head lights will on the second click. I tried unhooking all the wires connecting to that control arm and still nothing when i tured the key. I could still hear the clock ticking aswell. I am thinking about taking the dash out I also need to replace the heater core, do some rust work on the fire wall and under the battery, and carpet aswell as some lights and what not behide the dash. Thank you.

Hi need help again, My car have a strange isue i saw a few post here that talk about it with no clear solution. I run pertronics pickup and 3ohm flame trower this worked fine for a few year 5 i think now it run inequal sometime it runs fine and sometimes at around 4k rpm it dies i lose fire on some of the cilinders and this only apens under load. I tried using 1.5ohm original coil same thing. tryied to bypass tachometer work for about 30miles than it started to do same thing, Note the 30 miles i did were on the highway and not to fast lets say around 70mph. any input would be great.

Hi, so I just finished rebuilding the engine on my 1973 240z and it turns over, but no start. Its getting air and fuel so it seems logical the only reason its not starting is the spark. My car has an MSD blaster 2 coil and an e12-80 module. We used the multimeter and determined that both the positive and negative side on the coil are getting around 12v, is this right?? Same thing goes for the b and c on the module. I am assuming the negative is supposed to be grounded, so am I missing a connection on the wiring harness? Or is the module messed up? Thanks for the help! I have it hooked up like this diagram:

Folks, I would like your suggestions on an ignition coil. I have 78 280Z that is running fine, but am considering replacing the coil due to the fact that I'm sure the coil is the original one and is showing some rust spots. Would you suggest replacing with an OEM coil or one of the 'hotter' coils? Thoughts? I appreciate any comments. Bob

I have a 1974 late model 260z. I am getting no power to the coil in any ignition position. I have replaced the ignition switch and lock. Needed a new lock anyway. I tested for continunity at the switch connector with the switch in the different positions Seems I have continunity. I checked the coil with a multi meter with the negative end grounded to the strut tower bolts and the positive on the coil positive, no power then I did the same for the negative side, no power. I did the same with the coil resistor at all connections...same thing no power there either. Where could I be losing power from the ignition switch to the coil.

I have been working on my Z for almost 2 years now, and what an experience! I am getting it back to really good condition. It has an electronic/push button start, and the tach is not functional. Anyone know where the tach should be hooked up to? Thanks!
