My daughter backed into a fence post and now it wont even crank. If i disconnect the battery and reconnect it, it will crank but not turn over. If i try again it wont even crank. I checked the fuel pressure and its fine. Any ideas?

 

Its a 07 h3 with 3.7L

 

Are you still using the crappy azzed OEM Battery Terminal Connectors???? Been a bazillion posts on hacking them off and replacing with a quality aftermarket set to achieve a secure ans consistent battery connection.

BTW.... when you crank a vehicle it means it IS turning over.

Voltage of battery at rest?

Is the little lock symbol light up on the dash when trying to start it? If so, look up GM Passlock.

 

Did you may be end up shorting the wiring by the back bumper?

 

Thanks for the replies, i do need to change the terminals. I found the problem. A while back i tried a cold air intake. I ended up removing it and evidently i missed a sleeve. When she was backing she got scared and missed the brake and slammed the gas instead. When she floored the gas that sleeve got sucked into the throttle body and stuck the throttle open. So when i tried to start it, the system knew the throttle position was wrong and kept it from starting. Its running fine now

Just when you think you've heard it all...

 

That will go down in the annals of H3 History...

I did fall for the suggestion of the short in the hitch wire harness. That was a good one...
