No spark, no start....

My Jeep randomly died pulling into tha gas station a few days ago, and now it wont start. I checked it and Im not getting spark at the plugs, and then I checked it coming off the coil. No spark there either.

So what else do I need to check?

Check all your connections and be sure they are clean. Next check your coil wire and coil. Then your cps and your ecm.

Sounds like a bad coil. Mine did exactly the same thing and that's what the problem was.

Check your fault codes by cycling the key. Judging by the number of post you have I know you know the routine. Does the fuel pump cycle when you turn the key. Chances are its the Crank position sensor.
