What would cause the fuel pump to not stop running? I finally had to disconnect my battery. I started for the car first time and it ran fine (engine swap TBI to TPI), but now fuel pump will not stop running.

did your car have an in tank pump before the install? some how there is constant power running to it. check the relay, maybe it fried in the open position, this happend to me once with the fan relay.

It did have an intank pump for the TBI, I changed to a Walbro pump for the TPI.

The pump works correctly today, fired the engine, broke in the cam, set the timing, and no problems. That is very strange, but I am not going to complain.
