Oh no! What'd I do?!
Hey guys, need a bit of help.
I tried searching but didn't know how to type in symptoms.
Edited: '01 XJ 4.0L
I was testing my injectors with a screwdriver near an exposed injector wire. The screw driver touched the injector then the exposed wire and *zap* *spark* followed by the engine shutting off. Now it just cranks with no signs of starting.
Did I blow the Crank Position Sensor?
Any help would be greatly appreciated.

Here's a pic of your Power Distribution Center. Note the fuse marked IGN RAIL COIL FUEL INJECTORS. Check to see if it is blown.
Also PCM and ASD. Check these as well.
Edit: The fuel injector driver in the PCM for that fuel injector you sparked may be smoked. These FI drivers are touchy and can be smoked even with a low impedance fuel injector.

Oh thanks! Might go check it out later. I'm a fair-weather, backyard mechanic. Windy and low 30s here.
Love this forum. Will keep you posted

Ok tested all the fuses in the distribution center. All good.
Tested connector B and C on the Crank Position Sensor. As I'm to understand it, it should be an infinity ohms reading but it's reading 140. Do I start by replacing that?

Why don't you check for spark first before replacing stuff you don't know is bad.
I'm not familiar with the 2001 setup, but why would you think you "blew" a CPS when you were messing with the fuel injectors? I'm not even sure how a CPS is "blow-able"?
