Backstory: Just purchased a 98 GST stock other than injen intake, TurboXS RFL BOV, and a muffler. It needed a fuel tank, which I installed tuesday. I ran it fine wednesday-friday morning no issue. After work yesterday (friday) I get in my car to go home and it starts with a rough idle. I give it a little gas and decide to reverse it and see if the rough idle would go away once it warms up, it dies.

Problem: Car will start most the time but rough idle. If you give it gas it stays on but the rpms don't rise much. I floored it in neutral and it only went up to like 5k but very slowly and limp. If you don't gas it then it just dies in a few seconds. My co-worker was behind me when I first started it and reversed it and he said he could smell I was running rich.

I did a lot of searching last night and this morning and found many possibilities. As a full time college student and full time job, it's hard for me to go down a list of every single thing I found. I am hoping someone can help me pinpoint the issue. The possibilities that I found online are timing off, cam position sensor (this thread, exact problem I am having. Except my reader appears to be broken because it won't read the codes. I know I had P1105 since I got the car, not sure if any new codes popped up), and maybe fuel pump.

I took 2 videos just now. First one shows rough idle and die, second one won't even stay at idle anymore just dies.

Also, isn't the cam sensor supposed to be in this picture? Or is it located elsewhere? I don't see it.

:( Looks like your going to be setting the timing.

First I'd check to see if the tensioner bolts are loose..

If they are, that could be the problem, if not, then it will need to be replaced.
But while you are there, to save you time and money down the road, and since the car is new to you..

Replace the water pump, tensioner, timing belt, and balance shaft belt to start, because if that belt breaks, or goes off time too much, you will be replacing valves or more..
 
So timing is good from what someone who checked it told me. Fuel pump got replaced and now you can hear the pump turning on but the car just cranks still and won't start.
