2004 SRX no crank no start , someone used this truck to jump start another car and when it was done and he went to drive off the car shut down...all POWER and GROUNDs to ecm good.....replaced ECM but i m unable to communicate with ecm to program....all circtuis to ecm are testing normalll need help

Did you check all the fuses? Do the lights come on?

the dash lights up no problem there ,everythings powers up just cant comm with ECM

Hopefully, it'* not the ECM. Make sure to check the fuses under the hood, in addition to the fuse block and passenger block ones.

And what engine do you have?

he could of connected the batteries backwards and the car still would start. sounds odd but german cars have this problem cause they make both the pos and neg cables black and people were jumping them bass ackwards!! Good Luck!
