Hey I'm stumped I've checked the fuel pressure at idle it is at 45psi I put a new throttle position sensor in it I can keep it running better if I use carb and choke it will run a little better I can not give it any gas. Any help?

 

Update... I just replaced the alternator before all this started happening. I said he'll why not and unplugged it started it up and it ran just fine is it the alternator? I'm going to replace it again...
