Re: Cranks will not start 1999 Cherokee
Go over all your work again.
Try to crank it again, might take a good 6 tries to get the fuel up to the injectors, if you smell fuel stop. Your just flooding it at that point. Give it several minutes to clear.
If no go try it with the starting fluid directly into the throttle body.
If still no start I'd look into the spark timing using the link I posted above.
