1990 XJ WILL NOT START- Help please

So, Iíve got a 1990 XJ that Iím about to light on fire.

The Jeep will turn over, it has spark, and it is getting fuel. It was just running a few weeks back and now it will not fire up anymore. After I try to start it, when I turn the key back from the ďcrankĒ to the ďrunĒ position, the injectors start to fire uncontrollably.

Iíve checked the CPS, (stator/camshaft position sensor), and the ECU.

I have 10 Xjís here at the house and have never had this issue. Starting to think there is a short somewhere.

Iíve got a video if the injectors pulsing but canít figure out how to post it.

Any help would be greatly appreciated

Also, the only light that comes on in the diagnostic/idiot light panel is the “BRAKE” light. It is only lit up while the key is switched to the “crank” position and the starter is turning the motor over.
