I parked my 1989 RX7 about two weeks ago and it was running fine. I went to replace the factory radio with an aftermarket. I used the wiring kit for the radio only to find out that the aftermarket radio was not working properly. I decided to put the factory radio back in. Now the factory radio is back in and working properly and the factory alarm is functioning properly as well but the car won't start. I know that I'm getting fuel to the motor and I know I'm getting spark through all the plugs. The car is turning over but won't start. I'm at a loss on what to try next. Any help would be great.
