ecc relay power question

[mustang_montana]

still trying to figure out why my fuel pump wont come on, im thinking my new ecc relay is shot but i checked the plug for power and heres what i got:
there are 4 slots, 1 has constant 12 volts, and one has 12 volts when key is on. the one with constant power is #4 when looking at the actual relay, and the one thats on with the key is #2. so the last one is #3 and its supposed to have 12v and be tied in with the fp relay, but it has no power. so im wondering if anyone knows if there is a fuse link that could have broken this circuit. i cant figure out where exactly it gets it power from, but according to the diagram its connected with several solenoids and ends at the ecc.

<<there are 4 slots, >> 4 connections

<<1 has constant 12 volts>> Correct

<<one has 12 volts when key is on>> Correct

<<the one with constant power is #4 when looking at the actual relay, and the one thats on with the key is #2. so the last one is #3 and its supposed to have 12v>> What happened to the 4th terminal? #1 by your definition.

<<and be tied in with the fp relay, but it has no power. so im wondering if anyone knows if there is a fuse link that could have broken this circuit.>> No.

the 4th terminal has nothing, neither does the second(the one connected with the red wire that powers the injectors/fuel pump etc). i dont understand why there kis no power to that one unless the relay switch is busted and thats how it gets power.

I don't understand, make a sketch.

12V in Run or Start is R/LG
Gnd is BK/LG
12V at all times is BK/O
12V to Fuel Pump Relay coil is ORG/BK

if you look at the relay itself it is the last plug on the row with 3. i spliced in a power line to power the fp relay so the pump primes fine, but the injectors arent firing. i may have a leak somewhere in the fuel system because i hear air when i prim the pump. i need to get a pressure gauge cause the tire gauge i used didnt show anything, but theres definetly pressure now, found that out the hard way.
