HELP.....Ok. I have a 87 n/a which would not start this morning. I flooded the engine by moving it 6 ft last night. (My mistake) So, I did the basic and advance unflooding tricks. No luck. New spark plugs. No start. So, I look to see if the spark plugs were firing. Try each spark plug to see if there was a spark. One of the leading coil had no spark. The three other have a spark. Could this be a bad leading ignition coil? And would that be the cause of my rx7 not starting.

Any and all help would be great.

Thanks,

Tony

 

No. The ignition is ok. Its just severly flooded. I recommend disconnecting the fuel pump plug thats buried under the carpet, on the aft side of the left rear strut tower.

Then put you foot to the floor and crank the engine for ten to fifteen seconds or until the engine momentarily goes varooom. Then reconnect the fuel pump plug and start the car.

 

Or push start it....

Leave in first or second, and push/pull it around the block a few times. It will start eventually!

thanks

How old are your plug wires? seems to me if one plug is not sparking, then there IS something wrong with your ignition, but I would start out small--check the little thigns before the big ones. and instead of disconnecting the fuel pump, why not just pull the EGI fuse from under the hood? that should do the same thing shouldnt it? or is it better to d/c the pump itself?

 

Just an FYI-If, as you stated, 3 wires are firing (1 leading, 2 trailing) the coil is fine. The leading coil fires both leading plugs at the same time. So, if one leading is firing, the coil is ok, plug wire bad, or insufficent ground.
The engine is definitely flooded. Remove plugs, clean them. You can even hit them with a match or propane torch, spin engine over with EGI fuse out until you see no "spray" coming out of plug holes. Put plugs in and try it. If you loose compression, you'll need to do it again and add some atf/oil into chambers. Try it again. Most say push starting best, although I have never had to do that.

 

Thanks for the input. I also check the ohms on the coils, and they are in range. Thanks for saving me the money on not buying new coils.

Maybe I'm old fashion, but I like to disconnect the fuel pump. That way when I crank the car with the pedal to the floor to get rid of the excess gas, I also have spark to help out, even if just goes varoom for a moment. Burns off the excess. I'm just partial to doing it that way.

Pulling the fuse kills the pump action but also the spark action.

If one Lead sparks, the other has to also, there's no way around that feature (with the exceptions like arcing from the plug wire to ground .

 

Got my car running over the weekend. Yep. It was flooded, Big Time. Big Thanks to everyone that post. If it wasn't for this forum, I would of never got my car running. Also saved me alot of money. Did seaches and posted a question about the coils, and found out the coils were OK.

Thanks again.

 

yeah, when it floods that bad the gas dissolves the oil in the engine, causing a severe loss of compression. That's probably part of the reason why it was so bad.
