Ok, intermittent starting problems, the starter would only engage after i would click the ignition two or three times, other times it would engage on the first turn. I took it to my mecahnic, he thought it might be the inhibitor switch, replaced it and the problem still occurred. Next step the starter solenoid. Replaced that and no luck. Next thing that was replaced was the starter, i got the car back this afternoon picked it up from his shop and it started perfectly. Went home let it sit for about three hours and go back out. Go to start the car and what happens, it doesn't start, it takes about three turns of the key until the starter went. Then when i got home i turned it off, then restarted it and it started on the first try....

Also when my mechanic tested the voltage at the starter he would get 11-12 volts i went to start he car, on the times the starter wouldn't engage he would get 7-8 volts...

Please Help


Thanks

 

Anyone???

 

Does the problem only happen after the car is warm? I've been told that the ground wire to the starter is very thin and poorly insulated and that after it gets hot the electrical resistance can increase to the point where it will not ground the starter. I had a simialr problem and after cleaning my ground strap and adding a few extras it went away.

 

hey dude...i have this same problem...but i have learned to just live with it

 

I've got the same problem... just started happening... I would be forever in debt(not really, but I would greatly appreciate it) to the person that can solve this problem...

 

The NHTSA issued a TSB for this issue:

Service Bulletin Number: G001/93
Bulletin Sequence Number: 017
Date of Bulletin: 9307
NHTSA Item Number: SB033441
Make: MAZDA
Model: RX7
Year: 1993
Component: ELECTRICAL SYSTEM:STARTER
Summary: NO/HARD START CAUSED WHEN HEAT FROM ENGINE INCREASES ELECTRICAL RESISTANCE IN STARTER WIRE. *LDG

 

Thing is it does it when its cold not when its hot......

 

yeah same here...mine will sit overnight...then in the morning do it. i thought it might be my battery since i went to a miata battery...but i did that A LONG TIME AGO...and this just started happening. i have a 93 and just hit 65,000 miles.

 

I have a 93 Rx-7 and also have the same problem. My garage changed out the ignition switch and it helped for a little bit but I still have the same problem. I have a turbo timer that I think is wearing out the switch .I have replaced the starter motor, battery, wiring harness, and ignition switch and am still having problems. The next try will probably be the ground wire when I get my battery relocation kit from M2. I will let you know how it turns out.
