For the longest time i thought i had an overheating problem. But after replacing the thermostat, water pump, fan clutch, and radiator i dont think that is the problem. i think i have a hot start problem. The car after getting to running temp is doesnt like shut off because its to hot, but once i turn of the car it gets tricky. in order to start the car. i have to turn the key and give it gas. and it will start. but everytime i start the car cold i dont have to give it gas. This is the weird part. The first time i try to start the car while it is hot and i dont give it gas it will almost start then sputter dead. if i would have given it gas it would have started but maybe …

I got a flasher relay from another car, but the ratings and part number on mine and the one I got are different. Is there any harm in using it or not? My flashers blink once every minute, or not at all..

Hi all- I just did the e80-early 80's skyline electronic dizzy conversion on my '71 240z- and I'm amazed at the difference-ie easy to start(dont need hardly any choke now) and seems revver. The vaccum advance units is stuffed in the electric dizzy but I've ordered a new one and will have it this week. Now my question. The vaccum hose off my carbie(std 240z carb- takeoff on left one) has no vaccum at idle but has lots of vaccum on open throttle. So.. the dizzy will advance at open throttle but not at idle. Shouldnt it be the other way around???with lots of vaccum advance at idle,then retard to normal at throttle to prevent pinging? If im right, shouldnt i take vaccum from…

Hi all- Please help me identify and find the wiring that is missing here. It is on a 1975 280Z -manual tranny-that is completely stock. The 8 pin connector that is shown in the pic comes from the wiring harness on the passenger side engine frame rail. From the FSM wiring diagram on Blue’s site, it appears that it has leads that go to the starter, alternator, neutral switch, back up switch, and oil pressure switch. There are other connections used –not used---depending on whether or not it has a manual or auto tranny. What is this piece of the wiring harness called and where can I find one? The car belongs to a friend of mine that did a restore, lost the part, and h…

any clues? the stereo is a sony explode yadda yadda yadda, wired to the orig radio hot wire (blue on plug) in my 77. Frame grounded. When ever you turn on the turn signal the radio goes black as in to loose power, it also sometimes does this when shifting into reverse, have checked all connections, fuses, and monitored the power whith a mulitimeter when this happens but see NO drop in voltage at any time! where would you start? 1977, 2600 Bored 30 over, mild cam, E-88, header (wraped), Trip webers, Msa areoII body kit, Paint code 232G, Tokico springs and struts, 83 5spd tranny.

I have located the harness and I know the appropriate wires (red and red/black) to connect to the switch. My question is what wires on the swtich do each of the harness wires connect to? The reverse switch has one remaining wire with a bullet connector. Does it connect to the red or the red/black wire? Thanks.

OK, here's a new one on me. The tach in my early '71 240Z (4 wire) suddenly this afternoon started to peg the needle at 8000 RPM any time the key is turned to the Run position, whether the engine is running or not. I suspect a problem with the tach itself, not the wiring as the ignition appears to be working fine, since the car starts and runs normally. Any thoughts?

I'm having a problem with some interior stuff. My Map light, dome light, glove box, key in buzzer, windshield wipe pump motor. All I know so far is that ther is no power to the wires for the motor and the fuse box doesn't have power either.I have figured out that all of this stuff is on the same circuit. Were should I start to find the problem? Help!!!!!!!!!!!! DeeDee

Car ran for about 50 miles then the tach jumped around and the car died will not restart. Put a rebuilt 79 electronic distributor in with a new E-1280 module. Wirring is correct. I even went as far as to energize the coil with 12 volts from the battery still no spark? Curious as to the relay on the firewall? Should i have to do anything with that doing this conversion? Car is a 73 240Z. Any help greatly appreciated :rambo:

I keep blowing 20amp fuses in the fuse box. when I blow a fuse the turn signals on the dash don't work, temp/oil guage, and the horn does't work. I went through 2 fuses today, definitely a problem. What should I do to fix the problem. DeeDee

Anyone know the circuitry for the electric door locks. I can't find anything on the circuit diagrams I have been able to locate. This for 81-83 280zx. it appears that there is some kind of latchup relay in the dash someplace cause the switch on driver door pulses current out through two differrent wires depending on lock/unlock. passenger door seems to reverse current when it lock/unlock but only two wires going there. Trying to put electric lock on a 81 w/parts from 83 junker. got the door switches and they work as I hooked them up to my working 83 as a test but not sure of the connecting wiring needed.
