I just got done doing my top swap on my 98 gp gt and everything went good started it and ran perfect, couple days later I went to finish my exhaust and went to start it and would not start. I spayed some starting fluid in and fired up but only would stay running if I held the gas down a little, I pulled the gtp pcm and put my gt one back and it fired right up and ran perfect. So I pulled that one back out and put back the gtp and still no start. I have fuel, spark,but i don't think the gtp pcm is firing the injectors. Any ideas?
