Post subject:  no start after warm up and what I found to fix it: UPDATE
For a few months now on my 05 , after driving and the engine is warmed up I would stop some place
(in this case shopping at a store) the jeep would not start , it acted like it was in drive or if you try to restart without turning the key to off , the first time this happen I thought it was a failed battery and since we were at Sam's I had them replace it, eveything was fine for a while and then it did it again .
So I cleaned the battery connections and it started , that that was my fix at that time to get me going ,

it got to the point after it warmed up it would happen every time I stopped. So I replaced those battery connectors thinking that was it. Nope still happens . so yesterday after getting tired of dealing with it I realized that I must be reseting some thing when I disconnect the battery . so when it did it again I pulled fuse 14 (ECM and starter relay) and low and behold it started right up, turned it off and try to start , no start , so next I found the starter rely and switched it with the fuel heater relay (same PN) and then it started and has since I did that , so that relay must turn into a latching relay when it warms up

Well I guess it is not fixed , because it is back and this time the only way to get to reset and start is to pull the battery cable :banghead:

Possibly a bad solder joint in the relay like the one in my and many other 1999.5 Jetta tdi's had creating a similiar situation except in reverse. (wouldn't start after cooling off) :5SHOTS:

anyone know how many amps would I need for a relay inline with the battery , crank amps ?

I am thinking until I get this tracked down, a ? normally closed relay that I push a button to open the circuit
from the dash ?

Maybe still a bad relay. Put the relays back in the original locations, if you can still fix the problem by pulling the starter relay fuse, change the relay. My guess would be that the ecm really doesn't like a stuck relay for the fuel heater (after you swapped in the bad one).

I already put that relay back and have a new one for starter , it does not do it as often now

I can try a new one for the fuel heater
