The car won't turn over and start, fuel pump is fine, along with the battery as well
SOURCE: 2006 dodge grand caravan-car won;t start.
Test at the spark plug if you are getting current there with a cheap spark plug tester, if not, it could be the spark box. ( it used to be an ignition coil on older cars ) double check the computer for codes which may lead to a cam sensor not giving the PCM information.
SOURCE: I changed the key batteries
stick the key in the ignition, turn it to the on position, remove it within 5 seconds, then hold the unlock button down and press the lock button 3 times within 10 seconds and release both buttons. The doors should lock/unlock to give you confirmation and your key should work.

No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.---------
To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.--------
The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.

Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
-----------
If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.---------
This will help.Thanks.Helpmech.
Testimonial: "Thanks. That was the best answer yet.I didn't want to hear that the PCM might need to be replaced but the car has served it's purpose through the year"

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned. To confirm the problem, the basic troubleshooting is required. Click this link below and follow the troubleshooting:------ http://technoanswers.blogspot.in/2012/02/car-starting-issues.html --------- This will help.
Thanks.
Maybe the antitheft system. Read thru this link
