Did this start after the fuel pump was replaced? Does the fuse blow instantly when the key is turned on?

my wife was driving and it just died out and didnt want to start no more. so i replaced the fuel pump but now the ecm b keeps blowing every time you go to turn it over.

The ECMB fuse powers the fuel pump so I suspect something is wrong with the installation. You may have the power wire contacting the housing in the pump module and that mighty dangerous. Try unplugging the fuel tank harness and see if the fuse stops blowing. If so, drop the tank again.

pulled the fuel pump relay turned it over and it didnt blow the ecm b

I said disconnect the harness at the tank. Pulling the relay doesn't tell you if the relay or the wiring going back is good or not.

ok thank you I'll let you know what happened

I started the truck after disconnecting the fuel tank harness and it didnt blow the ecm b fuse should I check the fuel pump also to make sure the pump is working

No, that means the short is in the fuel pump and the tank will have to be dropped and the pump inspected to find the problem. I suspect you have one of the wires touching the pump frame.

the pump was no good and it kept shorting out the fuse,i got a new pump and its running good now, thank you!
