My jeep Cherokee has check engine light and diagnostic code 22 it has a hard time starting and staying on. What is diagnostic code 22 ?
SOURCE: 96 Jeep Cherokee Sport Hard Starting
The Engine coolant temp sensor would ABSOLUTELY cause a hard start, but don't guess get the codes check again at Auto_Zone to make sure. Another cause of that kind of hard start is a dirty throttle body/ intake manifold. Use INTAKE cleaner and a rag clean the intake esp[eciall in the throttle body area. Good Luck

Take it to any Autozone or Advance Auto. They will check it for free! Probably other similar stores will do the same!

Answer
Hi ,
The code refers to the leak detection pump that is part of the gasoline
vapor control system which is for pollution minimization. It says either
that the pump switch or mechanical operation is faulty. According to a
Chrysler manual I have, you would find the pump, probably on the
underside of the vehicle by tracing the hoses related to the vapor
recovery tank that may be in the right front corner of the engine
compartment (I don't know Jeep designs) and then check to see if the
pump starts when you turn the ignition to the run position when the
vehicle is cold. Then remove the vacuum hose side of the pump and see if
it draws a vacuum. If it does, then the vacuum-detecting switch that
detects that the pump operation is OK may be faulty. If the pump doesn't
start or doesn't draw a vacuum then the power to the pump, the pump
itself, or the vacuum line may be leaky. Finally, the powertrain
controller could be at fault.
In any case, that is where the issue is, and it should not be a major
issue if it is handled by a knowledgeable mechanic. But you could check
it over yourself if you are so inclined. p.s. your best bet is to take it to a jeep dealer to get it fixed hope this helps please dont forget to rate my solution
