383 Stroker Fuel Issues

[Kyle Doiron]

I'm hoping somebody might be able to help me out. I'm having a fuel issue, we are pretty sure there is something electrical that is telling the fuel pump to stop pumping after the prime stage. Replaced the pump, regulator, relay under the hood and under the dash as well as the filter. We have wired the pump direct to power and it works fine so we know the pump is working properly. Motor is a 383 stroker
