Re: VATS trouble!!!
12 VDC on both injector terminals is normal. The ECM switches one of them to ground to fire the injector(s).
5 VDC on the VATS is normal.
You mentioned noid lights..I take it they are NOT flashing while cranking?
And IF the engine cranks over it is NOT VATS related. VATS only disables the starter.
If you are not firing the injectors, look for a bad ignition module. the ECM gets a refrence pulse from the distributor and when it sees it, it will fire the injectors.
If the module is good, look at the ref pulse wire from the distributor to the ECM.
It is possible that when you crossed the wires you burned up a quad driver in the ECM too.
