Yesterday my jeep stalled mid driving and it quit it took a hard start to get going i got it home from there it didnt start at all. we thought maybe it was fuel related and replaced fuel pump. well now it wont start at all at will crank two or three times and the started kicks out. i have good spark. good fuel. good air. what could it be

 

sounds electrical - did you check spark plugs for firing - might be a crankshaft position sensor or camshaft position sensor went bad.

 

I had a similar prob and I cleaned the terminals on the battery and tightened the clamps a bit. It hasn't had any prob since.

 

cps is always a likely culprit!! check for a bad connection, frayed wires... sounds like a short somewhere...
