Car: 82 GS (77,776.2 miles, so close to all 7s).

Story:
It starts up perfectly fine in the morning, sits at work for 8 hours, starts fine again, go in to store (10 min) doesn't start. All the accessories turn on but doen't make a "click" when you try to start it or crank over. It did this at an autox this past weekend as well (started fine going there, but wouldn't start between runs). I had to pop the clutch in both instances to get home.

It seems that it won't start if it was recently shut down. Is this the starter solenoid?

I tried to check it by hooking a voltmeter to the "S" terminal with the key in the "start" position. According to the FSM: >8v = starter malfunction, <8v = wiring. However, I didn't get a reading, should I assume this is the wiring or me testing it wrong? Or is it something else?


Thanks in advance.

Check to make sure the small wire that triggers the solenoid coming down from the
wiring harness has a good, stable connection. I had an issue very similiar to this
and it was just a loose spade connector that needed to be tighten up a bit.

It can also be symptom of the ignition switch itself, which you can get replacements
for from Mazdatrx and Black Dragon, I think.

Could be corroded battery cables...

This could be it. After examining the cables and connections more thoroughly, there is an open cut in the negative cable. Looks like I will be relocating the battery to the storage bin sooner than expected.

Don't you just love how the RX-7 tells you what upgrades you should do...

Kentetsu

lol, I know what you mean. I've upgraded damn near everything now, so I practically have a brand new car.

Well, I replaced the battery cables and no go. That wasn't it. Tapped the starter motor lightly to see if that was stuck, still no go. I am back to guessing it is the starter solenoid.

Any suggestions? Is the voltmeter reading of 0 the same as <8V, meaning wiring or a bad test?

Take it to a parts store that offers free testing...

I just bought a new one, I was under the impression that they were more expensive. I'll put it on tomorrow to see if it works.

Did your problem get fixed. I am running into the same problem, but I have had the starter tested and it came out good.

Well, everything is fixed. Here is what I did:
-New fusible links (30/60/30 amp) at the same time since my headlights were acting up. ($13)
-New negative cable ($10)
-New starter ($70)
