2002 town and country will not start intermittently. Been checked out at garage. Say they cannot find anything. Most times when try to start all warning lights come on.


Will not start how intermittently ? The engine won't turn over or engine does turn but won't start . Starter relay , lose connection . Checking power an grounds would be the first place to start , voltage drop test the main electrical circuits . Voltage Drop Testing the Starter

The starter circuit control is achieved by the starter motor relay ! It is located in the under hood fuse/ relay box or as Chrysler calls it ,integrated power module ! If you pull out the relay an look on the bottom where the pins stick out you will see four sets of numbers .30,87 an 85,86 ! 30 is B+ voltage . 87 is to the starter solenoid . If you jumped those two spots where the relay plugs into the starter would crank the engine over . The last two 85 an 86 are the control side .If you checked with a volt meter where 86 plugged into ,with key on it would show B+ voltage . The last pin is from the PCM - engine computer . When turning the key to start a signal is sent to the PCM to let it know crank has been requested , in return the PCM supplies a ground to pin 85 energizing the starter motor relay sending B+ voltage to the starter motor cranking over the engine . Here is another video on test from the relay base (where relay plugs into ) This is for a horn circuit but same thing . VEHICLE RELAYS Testing from the relay base The relay could be going bad , you never know .Replacing the relay mite not be a bad idea . Good luck , hope this helps !

Aurora 4.0 im stumped checked starer relay and car still wont start clicking ssound comin from backseat jumped it whats wrong


What year vehicle ? The clicking sound you hear from bake seat is probably a relay ! There is a fuse / relay box under the back seat ! How did you check the starter relay ? Just pull it out an look at it ? Was it #36 START 1 Relay
-- Starter Solenoid and PCM in the under hood fuse / relay Box ?
This relay is computer energized - PCM supply's a ground to circuit 447 which energizes the relay sending voltage to the starter S terminal engaging the starter . Do you have a test light or a volt ohm meter ? If you pull out the starter relay an look on the bottom you will see some numbers , 85,86 an 30,87 . match them up to the holes they came out of . Check out this video on YouTube ,you can check for voltage an computer control . Is the SECRUITY light lit on the dash ?

My 1997 park avenue is stalling. When it does the gages tweek out. The break instantly locks up. And now it wont start nor even turn over. Idk. But I need a lead


There are very specific diagnostic steps to follow when diagnosing problems on vehicles like yours ! An using a professional grade scan tool is key , because it will communicate with all modules on the vehicle ! A shorted module or a serial data bus malfunction will cause a no start , no crank problem !
The PCM has the ability to disable starter operation if conditions inappropriate for starter operation exist. The PCM disables the starter if the engine is running, if a correct VTD password is not received from the PASS-Key?® III module or if the vehicle operator attempts to engage the starter for an extended period of time.
The PCM controlled starter system consists of the following components:
?€¢
Starter enable relay #1.


?€¢
Starter enable relay #2.


?€¢
The park neutral position switch.


?€¢
The ignition switch.


?€¢
The starter solenoid.


?€¢
The PCM.


Is there a SECURITY light lit on the dash ? Your best bet is take to a ASE certified repair facility !

Engine starting problem


Problem is probably the starter motor. The windings probably have a burnt spot and wont turn over readly.

2003 Caravan No Crank, 3.3L


This is a bad PCM. Try to disconnect the security system first and if it still does not start then it is the PCM.
