Question about Generac 5622R GP5000 GP Series 5000 Watt Portable Generator
If it is new and under warranty, talk to Generac about getting it fixed.
If it is old and unused, it probably needs fuel system cleaned out. Carb needs to be removed and cleaned inside and out, fuel lines need flushing, filter changed and if it has an automatic choke, it needs to be checked because it sounds like it is stuck on.

I install and work on these everyday. If you hooked up the transfer switch you probable have a control wire wrong. check the utility power sense wire. That lets it no when to start in auto. it could be a relay or fuses. or a control board.

I have the 18KW model and was told that most alarms relate to a low battery. Make sure the battery charger in the Transfer Switch is properly feeding the battery or hook up a mobil battery charger to the battery and see if the alarm goes away. Good Luck.

SOURCE: Generac control wires
older model Generac only haver 4 control wires:
if it is the included wiring harness the wires should have their numbers stamped on the jacketing and a sticker should designate the proper screw to mount it to in both the ATS and the generator housing. hooking these wires up incorrectly often results in blown fuses and/or damage to the control board in the generator.

Its the Oil sensor just pack the oil sensor wires together with a smal screw and bolt and try starting if it starts your problem is the oil sensor they tend to go bad I have run through several myself . To avoid hassles I now have overidden the sensor but I check the oil level everytime I need to use the generator
