Twice in the last week I ran to the store and when I came out the car wouldn't start - nothing - dead! Then after about 30 minutes, it was as if it would reset and it started right up and worked fine without a problem for days. Was this some kind of computer glitch or what? And does it automatically reset itself? Has this happened to others?

 

Dead? So you turned the key and there were no lights on the dash? Or you turned the key, the dash lit up with lights, but the starter would not engage - THAT is not dead, that is a "mystery no start" that we've known about since 2007.

I had this happen to my car ten days ago, just got my RCM back from DJ today, in fact. All fixed.

 

It can also be a bad or weak battery connection.

 

THe test is the fan.

Car won't engage starter.

• Leaving key at "ON" for 30 seconds causes fan to run at HIGH speed - RCM is at fault (no output from the Engine Control Relay, so the ECU is not powered up).
• Leaving key at "ON" for 30 seconds does not cause fan to run at high speed - very likely battery, as this indicates power is available to the ECU but not enough voltage to engage the relay in the Pulse model, so no starter.
