Ive got a 1988 rx7 non turbo that refuses to run. Iv had it running good a few times since I bought the car but cant seem to get it running again. The past few times Iv had the car running I have had to adjust the tps using my multimeter but that doesn't seem to be working now. I replaced the plugs and that had no affect at all. I'm stumped and not sure what to do. Any and all help would be great.
