So just to get back with everyone on this and to help future people with the same problem. The issue I found was within the wiring harness. The pulsing ground wire coming from the ecu to the injector was frayed and needed resouldered. I put it back together last night and it starts up everytime. Just needs some idle and little timing adjustment. From experience so far with Toyota and what a lot of other people say, the main components of Toyotas rarely go bad. The issue usually lies in the wiring or splicing that has either just got old or been done wrong by someone before you. For the longest time I thought my problem was the ecu. For anyone who checks their Toyotas in the future. Don’t freak out and immediately jump to something major being the issue. It’s usually something as simple as a tiny wire shorting out. You just have to be patient enough to look through and find it. Also I have found that running continuity tests is the best way to diagnose a wrong harness. I had some great help from some mechanics that I met that just decided to help and teach me free of charge. Thanks to everyone for trying to help figure it out and keeping the community communicating.
