So the fuel pump does not prime or turn on unless I supply 12v power to the 5th spot (unused)for the fuel pump relay, even then when fuel pump turns onthe car will not start. Is this a pump problem? I did swap the multiport tb so that meant swapping the fpr over, could that be an issue? All I know is that pump does not turn on and when it is manually it still won't start. I tested the wires in the fuse/relay box at the fp relay and none had 12v power.

 

why not tell the year of your rig. the more info you give the better.

 

its a 98 4door 4x4

so today I found that pump now has pressure on its own but needa fp gauge to measure pressure at the filter and then the valve. I'm thinking fpr at this point if the pump puts out 60psi + its the installment of the fpr to the new multiport tb
