i was getting O2, crank and AIR codes that all went away when a metal clip was removed that was grounding them out on the block (or firewall maybe?) but they all came back indicating that the wiring. i didnt do the work so im not sure where this clip was or were the wiring is exactly. i thought it was by the ignition coils, but im guessing there is no way to get there from the top. i was wondering if anyone had a pic of the back of the motor from under the car of this area from say a pulled motor, or an empty engine bay to show the wiring?

i also have a similair problem with the MAF loosing voltage somewhere. i saw that the plastic heatshield was broken right between some hoses and the valve cover, so i taped that up as best i can, but i dont know where the wire goes... seems to almost go under or through some passage on the intake manifold?? where does it come out on the other end?

lastly, can anyone tell me where on the ECU all these wires connect? be much easier just to varify where the shorts might lay if i know where they were on the ECU... hell, they could just be loose there for all I know, but RAVE and wiring diagrams dont mix with me!

 

Take pictures of the areas you are talking about, or mark up some other pictures.

I have 2 motors out right now, both with harnesses. I'll take pictures for you, but I can't tell what the hell you're talking about by your description.

 

ECU Harness:



The ECU harness goes to the firewall through the hole right here:



If you take off the kick plate on the passenger's side (left hand drive trucks) and look in there, you'll see the ECU and where all of those plugs connect to:



Also:



Note that the upstream O2 sensor plugs have brackets attached to them. These are held with bolts through the bell housing into the to block at about 10:00 and 2:00.

 

PERFECT my friend! this will help, gunna give it a go tomorrow see if i can resolve these issues.
