    Turn the key and car won't start. No noise at all from engine trying to turn over. All electrical devices work though, radio, lights etc. Usually have to lock and unlock doors to reset anti theft system, then have to hold key in start position for a few seconds before it starts

    Last November this happened for the first time - turned key, lights all on, engine did not turn over at all. Dealer said poor connection to starter removed, cleaned and re-secured both + & - cables. Van was fine until mid July. Same problem. Dealer replaced relay, still didn't start, now does intermittently. Dealer claims no knowledge of this easily findable problem with the Vehicle Immobilizer Control Module. Huh? Reports been going on for last 10 years!

    Been having problems for last six months. Dealer changed anti theft module three weeks ago. Two day later same issue. Returned vehicle to shop following Monday. Dealer had vehicle two days with no issues. They cleaned terminals on starter and swapped relays. Next day I had same issues twice. Worked fine for 1 week. Then last night issue returned. Sometime have to turn key up to 40 times before it will start.

    The car starts and runs great but occasionally will not crank. All the proper lights come on the dash, everything else works fine but no crank. It may crank again on the next attemt or not for 10 -20 min. Some blogs say to thump on the relays in the cabin fuse box or the engine compartment fuse box. I have done so and had no luck but then suddenly it will crank and start. I have no clue if the thumping helps or if it is just coincidental.

    My '06 well-maintained Sedona is randomly refusing to turn on despite having replaced the battery 5 weeks ago. When I turn the key, all electrical systems are fully functioning but the engine is completely silent. Both times this has happened, it has self-resolved after about 20-30 minutes. Alternator checks out totally fine. Dealership stumped. I will be printing out this thread and taking it in to them. Thanks for the help!
