First a Code 54 - now no power

[Magic071]

I only see the two relays....there doesn't seem to be any others.

Try one from the A/C or something.

There is no reason to buy a new one until you know the old one is bad......remember the pump?

[Magic071]

Okay....the other relay doesn't fit...it seems to be an opposite plug....it is backwards compared to the fuel relay. I don't have a/c or anything...this was the bare minimum packaged vehicle and I bought it second hand.

[Magic071]

I have pwr at the orange/blk wires, but also the green wire...which is very weak. Any suggestions?

[Magic071]

I have checked the orange/blk wires...they have pwr. But the green one does too, only just a small amount of power.

[Magic071]

The relay is working...still don't have power to the plug that plugs into the fuel pump. I am mapping the wiring to look for shorts.

If the relay is clicking then you need to test it's contacts. There should be 4 wires going to the relay.
With the key off, one will be hot and three will show no voltage.
With the key on three should be hot and one will show no voltage.

If only two show 12 volts with the key on, the contacts inside the relay are bad.

Your relay wires orange/black=ECM+oil switch
green=mod
black=ground
gray or tan/white ?=power to tank should match at tank either or
