1992 Chrysler Le Baron help with code 37

I'm not getting any gas to my engine at all. It cranks just fine. I have a half a tank of gas. It has been sputtering in the past. A lose of power while on the road at times. Now it just won't turn over. I bought a fuel relay and an asd but first I ran the codes and came up with 12.37.55. Called napa where I got the relays and asked them have they heard of an throttle body unlock solenoid. They told me that's my problem. My question is first. Where is it and could this really be it. For 26 bucks lol

Do you
have the same problem?

Check for spark and fuel, do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/COP/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
