My G35 was parked for about a month and will not start. So far I have drained the tank and added premium fuel, tested fuel pump pressure (50+lbs), checked fuse under dash and checked for pulse (yes), cleaned MAF sensor today. The red light on the dash blinks but does not stay on and there are no codes. Wil run by spraying either. What am I missing? Thanks in advance.

Sounds like no fuel to injectors. May want to pull a plug after a short cranking session and see if the plug is wet (also look in the combustion chamber).

Thank you. i agree. I did purge the line to the fuel modulator and sprayed (too much) starting fluid hopefully to get past any bad gas. I can pull the plug but doubt it is wet-ether stops, engine stops.
