Stupid question but have you checked your fuses?.

Did you check the fuel pressure? Is should be 284-325 kPa (41-47 psi) If it is to low the engine won't start. There may be a problem with the fuel pressure regulator. Is the security light on? If it is the vehicle won't start. you may have a problem with the passlock system. Did you check all the fuses in the under hood fuse box? There is a 20 amp fuse labeled ECM B that supplies power to the fuel pump and fuel injectors. If the fuel pump only runs when you crank but quits when you release the key you probably have a problem with the crankshaft position sensor. If you drop me an email (address is im my profile)I can send you the diagnostic chart for a no-start.
