Hey there i have a 88 rx7 non turbo. I have problem with turning the car over through my ignition. the car starts first couple times no problem when i havent started it in a couple hours but after i turn it over a couple times and run it turn it off and try to turn it over again it wont... i can turn my key for the longest time every thing sounds right starter is running i can hear is but wont ignite and run, just stall... BUT if it has to come down to it we can push start the car very easily with no problem. What could this problem be ?
