How many times have you tried to crank it and got this. It can be caused by a multitude of things. Low voltage from the battery going bad, faulty ignition switch, other service codes such as throttle positions sensor failure, MAF sensor failure, etc.

If you know someone that has a programmer for the H2, they can clear the computer codes and possibly get you back going for some time and also read the fault code.
