Hey I have an 03 caravan se that's giving me a hard time. I'm trying to find all the grounding points (specifically one for fuel pump) because I'm not getting pressure to the rail and I've changed fuel pump, filter. Any help would be appreciated.
Since you are seeking information on the ground circuit I assume you are getting power to the fuel pump. If not, then you have a bunch of other stuff to look at. Anyway, here's the wiring diagram for the pump and the ground location. You are looking for the G302 ground.
I figured it out. Turned out to be a bad pump out of the box (had just installed a new one). Put the old one back in and cleaned grounds and was able to get fuel pressure back to rail. Bad news is that I think that I reinstalled the fuel injectors incorrectly and ended up getting fuel sprayed all up under the hood and leaking on floor. If I take out old fuel injectors do I have to replace O rings when putting them back in or is there a trick to seating them properly?
