I just bought a 1990 626 and all of a sudden it quit getting fuel to it. We are thinking that since its fuel injected something triggered the emergency shut off. We cant find where the switch is. Any help would be greatly appreciated!!!!!

 

no.. fuel shutoff switch is called the inertia switch.. and that would only come in effect if you got hit hard.. i bet its your fuel pump which is inside the tank

 

well now my fuel pump is working but the air regulation thing isnt working i need a wiring diagram to find out why or what wires are supposed to be where This is rather upsetting due to the fact i am a single mother and i live 17 miles from where i work and from a sitter for my daughter if any one could help it would be great

 

Hope I dont insult anyone, but did you check if it had a fuel relay under the hood, my 94 626 had that happen a 30amp relay went bad and wala no fuel.

 

What is an air regulation thing? Are you talking about the air flow meter on top of the air cleaner housing?
When you said "it quit getting fuel to it" was that no fuel when running but would have fuel pressure during cranking?
