the first thing is to check for codes ,although the codes can give a clue as to what is wrong .
if you have a rpm/tach gauge in the dash ,you can see if that moves or shows rpms while cranking the motor over .
if it doesn't then you can have a bad crank sensor as that usually points to along with no spark to the crank sensor .
another thing is the ignition coil
,that can be checked out at many parts stores .
again a scanner is really needed these days to help trouble shoot and diagnosing these vehicles
here is a very good site for checking things out for your vehicle .
it is called
this explains things well and gives you test to check things out
Usually if a coil pack is bad it may show spark on some cylinders and no spark on others .
it can/t hurt ti get the coil checked out either ..jazzmaster ..
