1986 7mge supra not starting

[Jrsinnovations]

I need help. Can any one help me get my supra running? Here is the story I bought a 1986 supra n/a I drove the car home but it was running rough so I decided to change the spark plugs with ngk iridiums. Found that the throttle was becoming rusting out so I replaced it and I replaced the mac too since it had an aftermarket one that was giving me problems. After replacing this and the distributor the car did not start. I have since then try two used mafs two used ignitors two coils and one ecu. And nothing I'm clueless the car doesn't behave any different when I disconnect the distributor. The ecu or the ignitor. It turns over the same whether they are plugged in or not. When installing the distributor I made sure that 1 cyl was at zero. Can any guide me in the right direction please
