My Grandson stopped for gas and his 2004 Limited would not start. He said after several tries it had a loud bang and there was smoke. He tried hooking up his code reader and it would not communicate. Any thoughts? I assume the bang and smoke was a backfire. The OBD2 issue I have no idea. He lives a distance from me so it is difficult to trouble shoot.

If the ODBII does not communicate let's start with the battery and RCM. I hope the computer did not die.

Re: new issue
A failed RCM (if it won't engage the starter) or Crank sensor (if it engages the starter but won't start) are common "no start" causes.
If the code reader can't talk to the ECU, then I'd suspect that the RCM not powering up the ECU.
But none of this explains a 'loud bang and smoke'.

Re: new issue
But a backfire, if that is what he really heard, means the ECU is powered up because the plugs fired.
There just is not enough here to go on. As someone else asked, did the car finally start and run? Has it done it again or is it doing other weird stuff?
Re: new issue
Okay, he finally responded after getting the following messages on the DRB2. It cranks and tries to fire. There are four messages. They are "linking error", "Verify that the ignition is on and check that the scan tools drb connector is securely connected", Verify that the vehicle is DRB2 compliant" and " Turn the ignition off, wait 10 seconds and turn the ignition back on". I will try to drive out there and look at it soon.
Thanks for any thoughts.
