1993 nissan maxima 3.OL i replace the timing belt and spark plugs an there is a misfire on number 2 cylinder the belt had broke while driving on the highway could it have cause the misfire on number 2 cylinder what all i need to check?
Check the compression on cylinder 2, a valve may have damaged the piston.
will it hurt anything if i drive the car?
If a valve has damaged a piston you may have small bits of metal in your sump and possibly in your oil if small enough which could cause further damage, I would get it checked as soon as possible, if the compression on cylinder 2 is the same as the other cylinders then the problem is something else.

Breaking a timing belt while driving can drop a valve. But I would try spark plug wires first.

yes its possible, start by checking the spark plug and if the saprk plug wire is shorting down in the tube. if all is ok, then check compression.
SOURCE: need to know where number 3 spark plug is located on 2004 Nissan Maxima
Wow a lot of suggestions and Zero answers. I own an 04 Maxima and cylinders 1, 3, 5 are near the firewall. You can access cylinder 1 and 5 without removing the intake. I found cylinder 3 difficult and i had to remove the intake. When doing this remember to replace the intake manifold gasket. Most parts stores will only sell the kit and not the upper intake gasket alone. Price should be $75.00 for gasket set.
Cylinders 2, 4, 6 are up front near the radiator.
*** Tip... if you buy new coils place them on the coils 1, 3, & 5. It will prevent you from having to remove the intake later. Especially cylinder 3!!!

SOURCE: what can cause no spark when cranking?
If your doing a lot of cranking and testing, You need to hook up battery charger or use jumper cables to see if spark comes back. Make sure the battery has a full charge and connections all good. Even if battery is only down a couple of tenths, it might make a difference. 12.6 volts is the generic spec for a full charge. I have seen starter motor taking all the voltage, not much if anything left for ignition system. Could be other issues?
