Help me to find the problem!

The OPS triggers the relay, the relay gets it's power from a battery source to power the LP
 
Adding a relay takes the electrical load off the ops. The electric load on the ops causes them to burn out much sooner. This causes problems with fuel supply that not only makes the engine run rough. But wears out the ip sooner.

Now I connected the relay to the ignition switch. What's the difference?
 
One more question. When in the tank is a little fuel engine will run bad and very bad start. Is it to dirt in the tank and dirty strainer?
 
Ignition switch is fine in my opinion. GM did it to meet legal standards so that if there is a crash when the engine dies the lift pump can't pump fuel everywhere for a fire. From what I see on YouTube there are never any crashes in Russia:eek:

I would drop and lean the fuel tank. Get rid of the small screen sock inside of the tank and mount an external fuel filter on the frame rail before the lift pump. This will eliminate any problems of plugging up from debris in the tank. At least drop and clean the tank for now if you can't spend the money on the external fuel filter currently.
