Re: "no start" problem with Barb's (wife) 78 280 Z with auto trans. and factory air.
Stock car
1. Turn key to start........nothing!
2. Click from right footwell? starter relay?
3. Battery NEW, Starter NEW, cables clean etc. Jumpered hot to start terminal on solenoid. Engine cranks fine. No fire.
4. Jumpered switch on auto trans (in gear lock out). Nothing...
5. Connected temporary 12V lamp, start terminal on solenoid to ground. Key to start, No light.
6. Book says to examine ignition switch contacts for loose connections etc........Should I try this next?.

Thanks for listening to my tale of woe, but must get the Z running to take to the Motorsport show in April..

Thank You for your help!!!!!
Sam and Barb.

Hi Sam,.

Doc here. You sound like you have a voltage drop problem. This is common when terminals get corroded through time. Start at the ignition switch. Take a hot connection and jump to the black/yellow wire with the car in park. By the way when did this start happening?.

Next thing that I want you to check is with the key, on does the red light come on in the voltmeter, and the brake light come on? Have you got a voltmeter? Have you removed the fusible links to check if there is one that is burned under the insulation, so that the wire is not connected inside..

This happens many times when someone is replacing the starter and doesn't remove the battery cable before installing the starter..

Please get back to me Sam, so that Barb can be "Zing"! Did you get snow up your way last night?.

"Thats what I get for going to Clutch-Mart" "Frosty" wrote Doc: "That is what I get for getting the job done at "Clutch Mart", And yes there is noise when the clutch is disengaged or the trans is in neutral. Any info will help." Read Doc's answer to Frosty and other Datsun enthusiasts who have sought his advise for the last couple decades on Doc's Tech pages.

280Z Dies SudenlyTravis here(Zonc #98029), in Fresno. I have a problem with my 1977 280z which I can not figure out. It started today. Just driving down the road the car shut off, I disengaged the clutch and it started right back up. I drove it home only about a mile. Tonight I drove it to FSU and it shut off 3 times on the way there, while it was cold and running at temp. I just hooked up a test light to the fuel pump and drove the car. The light is inline with the pump so when the pump is getting power the light is on.
