Thread: 00 GT wont start...where to go from here?

You should always have power aka positive voltage at the injectors. The pcm toggles the ground to operate them.

Check your ICM connector and crank sensor connectors as well. Unplug your maf and map sensors. Then give it a try. I have seen a map/maf reading keep the pcm from giving the cylinders fuel.

I got it to run. Since the MAP KPA was at 180 ish and i changed out the sensor and checked the wiring and didnt get it to go down, i wired it with the signal and power backwards to get me down to 41 KPA. after i did that the car started right up no problem. So clearly something in the computer disabled the injectors when the KPA is to high or out of table reach.
