Hello everyone, this is my first post. A week ago my 85 wouldn't start so I checked if I was getting spark at the plugs and sure enough the two lowers weren't sparking. So a quick trip to the local Autozone and $25 later I have a new ignition coil and an RX7 that starts just fine. Until today that is, it wouldn't start again so I thought maybe the other coil now. But no, the same coil no longer works. what gives? Any suggestions on what the prob might be before I go buy another new coil? By the way, great website with loads of helpful banter.

 

i had one that fried a coil, it turned out the spark plug wires were bad. could also be that the coil they sold you was the wrong kind/style

 

just wondering what plugs are you using?

 

me again ...i'm new too ..just did the plugs and wires..plugs were njk's ..replaced with same brand only platinum..bosch wires.(say what you want) ..its runnin like a friggin top..try the njk plats...if you're using same brand disregard..just my .02$!!

 

my ? to you is what coil are you buying, try acc., or msd cost more but works great

 

The coil I just bought is a Wels C843 and the plugs are Denso. When you said you fried a coil and it turned out to be bad wires, did you mean the bad wires caused the coil prob?

 

no I had a cheap coil from auto zone Buy A brand name or you might get stuck on the side of the road at 10 at night like I did because of a cheap coil. and then pay for a big tow bill

 

yes!

 

ok, same problem again. I exchanged the coil that stopped working after a couple days for a new one and got new plug wires, put them all in and it worked for one day this time. any idea what might be causing this?
