Answer
Hi richard:

my guess it you have the wires crossed at the new plug. there are 4 wires a power for the pump a ground for the pump a ground for the level sensor and the siganl wire for the level sensor. the wires must be crossed. another thing to look at on thse cars is if it starts and stalls out the fuel pump on that car is 2 speeds the low speed pump is controlled by a ballit resitor that is in the r/f fender if you live in the rust belt like I do those go bad all the time. good luck.
