I bought a 88 N/A rx7 and it was in a fire. The fire wasnt bad but i replaced all the vacuum lines and the wiring harness. now when i try to start it it only gets spark once. it will spark once like everything was normal but then it wont spark agian until i turn the car all the way off. Any help would be apreciated

 

check distributor,and the coils,check main relay is what i would check.Then make sure there wasnt an after market alarm that someone had spliced into your ignition with the interruptor relay or a kill switch you never knew until you look
