The van has had now 2 fuel pumps installed. The orignal one quit working. The first one I installed would work fine the just quit working. With a hit on the bottom of the fuel tank it would start up and run fine again. So though it had a flat sopt on the pump. Put a another new fuel pump in and it startted right up. drove about 10 miles and it started stalling. Would start up after a few trys and run fine for a while and then stall. In a 22 mile trip it stalled 4 times, then would restart everytime. now if I statr it in will stall just sitting in the drive. The plug on the pump was clean and not burned so was not replaced. Any ideas???

With you saying it’ll stall, sitting in the drive; can you hear whether the pump is still running during the stall? What is the fuel pump pressure?
You have to confirm whether this stall is still fuel/fuel pressure related.

Is the fuel pump suppose to run the whole time the engine is running?

I'm with Dan, very unlikely second NEW fuel pump being bad, you can hear fuel pump prime itself before engine turns over just by turning the key to the crank position but don't start it. The fuel pump would come on for a couple of seconds then cut off, until you start cranking it. By the info you gave, tapping gas tank suggest a connection problem ,unhook fuel pump connectr check for votage while cranking.

I have checked the voltage at the connector near the trans mount. It read 12.6?? volts.
The pump does turn on when the key is turned on.
I have not checked to see if the pump continous to run the whole time the van is running.
I will have to check the voltage at the connector when cranking. I can not get to the connector at the fuel pump it self with out dropping the tank back out.
I hope not to do that a third time but if I have to I will.

A fuel pressure tester would help you alot before dropping the tank again . Autozone rents these out.
