I have a 1987 Rx7 nonturbo that will not start. When I bought it from the guy the only problems we saw was that the alternator belt had ripped, so we replace the belt and the alternator. Later along the line we also replaced fuels injectors. I had my friend over and check on some things like the spark plugs and compression he said that my apex seals are probably bad, but I want to make sure the timing isn’t wrong or something before I pull the engine out. I’ll give more details if needed
