car wont crank after change pcm tcm and bcm all in same car and work before ill change them in this dodge,,

 

Moved from the Durango section to the Caravan section.

 

If it won't crank at all, the battery is dead.

 

Won't crank meaning when you turn the key nothing happens or all you hear is a click. Is that what's happening? Not everyone has the same definition for what "won't crank" means.

 

ok my mistake..here... car is dodge grand caravan 2001 whit 3.3 flexifuel engine ...change all those 3 box. car starts twice runs nicely maybe 5 or 10 sek and shut down, now red light in dashboard and no crank.. yes maybe click can hear but no crank...try reset take battery cables off and put together while ,,no help...lock and open doors whit car key and remote no help car have black key so no programmed keys. how i get this immo off or could this pin 21 heater center plug make this trouble in this car too..some wierd light action before change those boxes. lost oil light and blinks cruise control light..rough idle and so and so ..thats why try change those boxes.and only code was this battery code think was 1684.
