In this tread the relay install betwin OPS and LP isn't it? Wy?
Now I connected the relay to the ignition switch. What's the difference?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.
Thanks! Now I understant all. In my mind formed the puzzle.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
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.
Tell me pls what is "DRAC SPEED CONTROL BUFFER QDU "? What functions it performs?
