Start problem new battery good connection ok where is starter relay located?

Is the anti-theft light lit ? Is the starter relay good ? Do you know what a relay is ? Are the battery cables good ? I would start will the starter relay circuit's if the anti-theft light is not lit.! The starter relay along with the starter relay diode is located in the battery junction box in the engine compartment. The relay is K-22 . If you pull out the relay an look on the bottom of the relay you should see four sets of numbers 30,87 an 85 ,86 . If you take a jumper wire (12-14 gage ) an jump pins 30 an 87 if the battery cables & connections are good the starter will crank . Pin's 85 &86 are the control side of the relay . One of these comes from the ignition switch when is start position an the other goes through the transmission range sensor (park neutral switch) To ground or the PCM if yours has a V-8 . Now if when you jump pins 30 & 87 an nothing happens you have bad connections or the battery cable is bad . You can go on youtube an check out videos on voltage drop testing the starter circuit .

Possibly a bad alternator. No Start Diagnostic Basics EricTheCarGuy

A Simple Preliminary Car Starting Procedure
If your car won't start, try this procedure:

• Check the battery cable connections:

Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.

• Check the battery the simple way, like this:

Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

• Check the starter and solenoid:

If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.

Check the ground connection on the battery and the frame. Make.sure the battery posts are clean and free from corrosion. Most likely it's the ground on the frame

The most common cause of a non-starting car is the battery. It is either weak, (low voltage) dead, (zero voltage) or has bad connections. (corroded or loose) I will assume you have a fully charged battery with good connections. (both to battery and starter relay) Just becaue its new, don't mean its good or fully charged.

If you remove the starter switch lead (small wire) from the starter relay and apply +12v from the battery to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. (not to be confused with your key switch). If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken. Picture of starter switch prong on the relay is pictured. NOTE: sparks are to be expected, so don't be too scared.

Tilt the steering wheel down all the way and see if it starts, if it does then there is a main power wire loose in the steering columb. Thats all which comes to my mind at this time.

Try removing the ignition module, usually located right under the coil pack, and having it tested at Auto Zone or Advance Auto Parts.

check that the alternator is charging first

an easy way too see if its the battery is to turn the headlights on, and try to start it, if the lights dim the battery is to low, if the battery checks ok, then it sounds like the starter solenoid located on the starter it self, a new starter and solenoid should be around $100 and take about 30 min. to install

if you don't even hear the starter click, it's the starter, relay, or battery (turn your headlights on and try to start. if the lights dim a lot, get a new battery). if it clicks but doesn't spin, battery or starter. if it turns over but doesn't start, fuel or spark problem.
