A little more in depth explanation of our diagnosis.
We started testing the wiring harness for power, and also sensors and injectors for resistance. Injectors and sensors all had the resistance stated in the Repair Manual. This is where it gets mind boggling. There are 3 main plugs that go into the wiring harness for the manifold and everything hooked to it. The top plug (smallest), middle plug (middle sized), and the bottom (Largest). With all the plugs in we tested the sensors to see if they were receiving a signal. They were not. We unplugged the bottom plug, and we started getting signals to the injectors and sensors. We also got fuel pressure, but with that bottom plug plugged in, we had no power anywhere. We went over the wiring Schematics over and over for both the 2.2 and the 2.5 and came up empty handed. With all 3 plugs in we tested straight from the pin-out of the computer, and no power. But with that bottom plug un-plugged we got power at the computer. We decided to unplug every sensor and anything that plugged in passed the 3 main plugs, one by one, to see if we would find the culprit. We unplugged everything except 3 things with no luck. The 3 things we did not unplug were, One plug under the manifold on the passenger side, it is a blue plug that plugs into a little box with 2 or 3 small vacuum lines coming out of it, and then also the ground that is bolted under the manifold to the block, and last is the engine coolant temp sensor.
What we are guessing is that something is telling the computer something it does not like, or something is not completing a circuit. We have no idea what the something is, but it is definitely something electrical and not fuel related.
