Post 2002 tacoma 2.7L to 3.4L Cab Swap

I took my 2002 2.7L Ext Cab Base model with manual transmission off & replaced it with a 2002 3.4L Ext Cab TRD with manual transmission.
I installed the ECM from the 2.7L into the 3.4L cab.
As far as I can tell all lights & accessories are working.
I cannot get it started unless I run a positive jumper from the battery to the fuel pump.
Then it starts
I think I have to change some wires around at the ECM.
Anyone have an idea if I am correct and what I need to change.
