Galant E50 1.8 GLSI no longer works

Hello Mitsubishi and Galant friends Unfortunately, I have a problem with my Galant Bj 96 197tkm. He doesn’t want to start any more, but thought that the ignition will go without errors. So no gasoline in the combustion? Have starter spray introduced to the air filter then it ran out as long as you sprayed but then went out again. So many times fuel pump? If I take it off from the power supply and then it runs extra easily. Now I don’t know what to do. It’s not the power supply that’s still up to it. What’s left of the potential for errors now? Any fuses, or the immobilizer? Would be really nice if you could keep me going. Where I have to look and or what I should control. Is everything so annoying, just a few weeks ago, Zahnziemen crossbars at the top of the front made both tires brake at the front blocks and discs as well as two wheel bearings. Exhaust system is also top except for the flex tube. m make summer new TüV. thank you in advance beautiful greetings from the Baltic Sea
