You'll have to figure out if it is a fuel or ignition problem. Is the check engine light on ? Have you checked for trouble codes ? It could be a relay, the ignition module, coil, fuel pump, or a list of other things. Does it start back up quickly ?
What size engine 3.3 or 3.5 L ? Without testing ,would only be guessing . You need to look at a wiring to see what all is involved in the starting system for your vehicle. Then using a DVOM - digital volt ohm meter test the electrical circuits . Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter the vehicle info. year , make ,model and engine size . Under system click engine then under subsystem click on starting . Then click the search button then the blue link . Looking at the wiring diagram you will see a number of componets . Ign.switch ,when turned to start sends B+ voltage through the coil side (control side )of the starter motor relay .This would close the contacts sending B+ voltage from fuse A - 20 amp to the starter solenoid engaging the starter . If you look at the control side again , at the end , you will see the PCM - this is the engine computer . If it see's that the vehicle is in park or neutral it will supply a ground to the control side energizing the starter motor relay .
The battery maybe new ,but what about the connections and the cables ? Voltage drop testing the cables and connections should be done . Starter Voltage Drop How to voltage drop test starter motor circuit
plus testing for power and control of the starter motor relay should be done . Do you know what a relay is and how it works ? Relays Understanding Diagnosis and Testing Relayed Circuits Pt1
If no engine cranking (Turning over) then starter / battery / wiring fault. If ignition lamps work with key on and DO NOT DIM when starter is activated = faulty starter or wiring to it. If lights dim and chattering / click is heard = flat faulty battery.
If the plugs get wet, then you have a spark problem somewhere in the ignition system. Pull a spark plug and hold it against a ground while you turn the engine over. You need to see a fat blue spark. If not, check the distributor, spark plug wires and coils. An easy way to test for spark is with an inexpensive spark tester. This is a device that is readily available at most auto supply stores. If the plugs do not fire properly, check the spark plug wires for fraying or cracking. Next, you need to check the coil(s). If firing voltage is low (weak spark), measure the coil primary and secondary resistance with an ohmmeter. If it is out of specifications, replace the coil. Also, make sure the coil is receiving normal voltage from the PCM or ignition module. If it is low, check the charging system for anything that may be reducing alternator output (battery and alternator cable connections, ground connections and voltage output).
