Just some background info in case it helps. 1997 1fzfe 80 series 315k miles. Recently installed a new exhaust system which blocked off the EGR port. Ran fine for 3 min after the exhaust install then died and never started again. The motor turns over and it starts for about a half a second and it shuts off. I have checked a couple of things: alternator, fuel pump relay, battery. I ordered a fuseable link to see if that does anything. Here are some pictures and once i figure out how to post a video I will post one of it trying to start. If anyone could guide me in a better direction or help me with some troubleshooting I would really appreciate it
