Was your 77 converted or is it one of the 77 3.0 cars? Where is the fuel pump?

It is a 77 that had a 2.7 and I installed a 81 3.0 in it. From what I understand the the 76 and later had a saftey switch on the air plate and it would shut the fuel pump of when it is in the rest postion. The power would come from the starter until the plate was lifted by air intake. Mine is acting like the switch is engaged or the plate is up and that is why i want to test it to see if that is my issue.
Thanks
