Hey all new to the group here!!! I have a 98 GT 4.6 5 speed with quite a few bolt ons and a livewire ts+ tuner. I just installed a firewall mounted fpr and a oe replacement fuel pump from auto zone. Shortly after installing the pump my car started cutting out around 3000rpm once it warms up. I can shut the key off and start it back up and it runs great for a couple mins until it loses the prime from the system. I have my fuel pressure set at 38psi on the regulator and when it starts acting up I can watch the pressure drop to around 20 to 25 max psi at wot. I also replaced the ccrm from a low mileage one from a salvage yard. I didn't have these issues until I replaced the pump. Any help I can get on this issue will be greatly appreciated and happy motoring guys and girls...
