2007 jeep grand Cherokee crank but not start
Hi getu. Can you tell us a bit more about your vehicle and the problem, or how you might like someone to help you? Thanks.
A faulty crankshaft position sensor will cause a crank/no-start condition.
Tester
What tests have you performed?
compression?
fuel pressure?
spark?
does it briefly run on ether?
Have you at least attempted to retrieve any stored or current fault codes?
