gpp

how can i test a gt500 fuel pump to see if both pumps are running.ive checked the wiring harness and i think its right but im having a idle problem and low end drivabilty problem with my saleen sc so i want to make sure they both are running.im driveing the crew at jdm crazy over this so before i take it out and put the stock one in i thought i would check the pumps.chris and jim have been great help and i want to make sure the problem isnt my fault.
