2007 H3 Won't start!
Hi, newb here. I have an 07 H3 that is turning over but won't start. Wait 15 mins and it starts. The ****ty part is I bought this for my wife but she won't drive it because it happened to her aswell. So i've got a beautiful blue paper weight in my garage because I don't feel like being stranded either.
Ive seen in some forums that its the ignition switch but I don't see that it worked for anyone. Any feedback is appreciated. The truck is only under its remaining powertrain warranty. The bumper to bumper is done.
Please assist!

If the "Lock" icon is illuminated on you instrument cluster it is likely the ignition switch not sending the proper signal to the BCM and therefore it thinks somone is trying to steal the truck so goes into anti-theft mode. That is why it restarts after 15 minutes. Under these conditions, there are numerous examples on this and other forums of the ignition switch being the source of the problem. It is good place to start looking.

thank you
Thank you! I got the part today. Hopefully install it this week.

Did it fix the problem ? i'm having the same passlock lighting up in the dash , No Fuel pump buzz ..just cranking , waited the 10 theft differ minutes and starts like brand new, .
Was it easy to replace the ignition switch . will order one this week . Very frustrating to be stranded for 10 minutes..
When is GM going to post a recall on this ????? All H3 are having the same problem . My cylinder Head was replaced under warranty @23k miles ... that's a BIG one !

Hey, this happened to me tonight. I could hear the fuel pump turn on though. I ended up disconnecting the battery for about 20 seconds and when I reconnected it, it started fine! I'm going to buy an obdII tomorrow to see if there are any codes, but in the meantime are there any other common causes of this problem?

More than likely your problem is at the connector to the ignition switch. I have had an intermittent problem also and just wait exactly 10 minutes and it restarts.
Anyways I will be replacing my ignition switch, and clean the connector to the switch with electrical contact cleaner, and lube with dielectric grease( I use Nyogel 760G on all my electrical connections) . Amazon has the switch for $33.81 with free supersaver shipping. (ACDelco D1403G for M30 RPO -4 Speed Trans) There appear to be 2 different switches, 4spd or 5spd. According to Mitchell it calls for 1 hour to replace, or in my case approx. 4 beers. GL
