I installed the new relay ,but no dice.I we pulled the relay out and I have the constant voltage from the pump fuse.I then had the key cycled on and checked for voltage from the ecm to trigger the relay.I got no trigger from the ecm on the sockets in the fuse/relay holder.
I have the box unbolted and flipped over and the wires under the box don't seem to correspond with the earlier post.I only have a green with white tracer going up to were the relay is.I assume this is the ecm trigger wire?I fail to see a gray or black wire under there fo the pump or ground.There must be a circuit board between the wiring plugs under the fuse box and the top were the relays plugs in.I also have about 10 or 12 pink wires under there so that is confusing.
Now what should I be looking at to see what is causing the no signal to turn on the relay?
I also did check the pressure of the pump when I jumped the relay and it put out over 40 lbs.
So now what?
thanks
