My car is a 91 tbi Shadow. The computer I am using is an 89. I tore the harness out and made it to 89 specs. everything should be perfect. However, the car will not fire. I have spark as well as fuel pressure. My injectors don't seem to be turning on. I will figure that one out tomorrow hopefully. But i dumped some gas into each cylinder and the car still wont fire. It acts like it wants to but the most she does is pop a few times. It is almost like its outta time but i assure you it is not. Are there any things I am over looking or under looking? Has anyone done a tbi to turbo swap? Any help will be great thank you ahead of time.
