Hey every one,
I have a 1984 Rx7 and it wont start. See the thing is I have an 84 that has been through alot. It has about 180,000 miles on it I believe and it turns over slow and wont start. I checked to see what spark plugs where sparking and the top two are. I know both coils work but for some reason no matter what I did I could not get the two bottom plugs to spark, when on the secondary coil, to spark.. Now the really wierd thing is I can' push start it on a bit speed and get the motor to run but it is EXTREMELY ruff... Any one have any ideas.. is the motor just warn.. The stater is good and I know for a fact cuz it new, battery is new and have used several.. It started doing this every once and a while but eventually just stopped starting..Can any one help me. I'm low on time so I am not able ot give that depth of detail so if you need mor info just let me know. I would appriciate any suggestions.. thanks.

the top plugs are the Trailing and the bottom ones are Leading. The Leading plugs are the main ignition circuit, without those, it will never run smooth. its a good possiblity that your leading igniter is blown. the igniter is basically a switch that is part of the ignition system, one for the top 2 plugs (trailing) and one for the bottom 2 (leading). they are small black boxes attached to the side of the distributor. when you find them, switch them around and then start the car, if it runs good, your leading igniter is dead.
