Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Sounds like a bad fuel pump. Do you have a pressure gauge that can read up to 150 psi? If you do you'll have to reduce it to an 1/8" nipple so you can screw it int a pressure tap on the pump
