A while ago i've read somewhere that the volkswagon tdi series under bosch edc16 ecu are known to have similiar issue called hot start issue. It is solved by an update on the ecu done at the dealership, but ! this would be a premier if it happends to the jeep crd also... So i dont think this could be your issue.

SKIM module (where you plug you key in) could also act funny like that.

Finaly starter / starter relay.

If you have a tune try reload ori and see what happends, but like i said i'll be surprise that it has something to do with the tune.

Oh yes, I remember that now. Almost had forgotten it. I'm trying to remember what I did to blow that relay. I remember there were some other random things that were on that circuit also.

yea starter relay is $14 so i might change it anyways...

i should see about reloading my tune, i emailed Keith and he hasnt heard of anyone having problems..

i remote started this morning and tried to take a video but for some reason it wouldnt record sound lol
ill remote start again tomorrow and see if it starts fine then maybe start with the actual key

i have heard that sometimes the truck has a hard time getting signal from the key causing it to crank for a prolonged time..

so many possibilities!

Oh ... Is your issue only when using wireless start ? If so this could also be WCM :|

Are you parking on a slope? VW TDI's had an issue with Fuel filter fittings sucking air. If you were parked on a slope with the nose up air would suck into the system and all the fuel would make its way back to the tank. Resulting in long / hard start until the fuel lines refilled themselves. Make sure the filter fittings are not sucking air.
