      Your Corrado has to have 1991 California emissions with the PG engine for that diagram to be of any use to you.


      You need another diagram.

      Both diagrams are equal.

      This clamp box will be valid to fuel hoses of fuel tank and fuel pump?
      https://www.amazon.es/gp/product/B07...PNQ6T9Y5&psc=1

      Or it's preferable to buy the originals?



      Where goes blue, and where black?






      That fuel hoses are connected correctly?



      Sorry for that stupid questions, but I am a little paranoid at this point. I've checked the schemas, and in the case of fuel hoses I think they are in correct places, but I'm not sure about connections.

      I will like to lose the minimum time in this.

      Thank you guys

      Those Clamps look fine and much like the original Oetiger clamps.

      The Sender wires (blue/black) position do not matter. The sender is just a variable resistor so the measured value will be the same regardless of position.

      The hoses look OK, but without seeing the top, I can not tell. The top should have an arrow on each hose fitting (imprinted on the plastic part of each fitting). One IN (Arrow toward the cap) and one OUT (Arrow away from the cap). Make sure the OUT (Arrow away from the cap) comes from the center line on the fuel pump itself. The fitting on the pump housing that is off to the side is the return line from the Fuel Rail and should be connected to the Arrow IN.

      The only stupid question is the one that was not asked!

      Let's start with the good one:




      The bad new?
      I lost the following sensors: RPM, water emergency and pre-start check light, oil pressure and all MFA displays. The problem now it have "painted" the entire displays and I can't see anything:






      The fuel level indicator is working correctly (in those pictures can't we see it). So, the fuel pump I think it's well mounted and wired.

      Problem with fuel pump "header" connections

      Today, when I'm connecting terminals of the fuel pump, I noticed the black faston terminal is too short, so to reach the correct place I've had to twist yellow cable:




      Because yellow is touching black terminal, I put a plastic clamp between them... I really don't like to do this things, but I'm not going to lost another weekend because of that. I do not think this is the problem of the MFA not displaying correctly, I think it's only a coincidence. But I'm gonna explain more about that in a next post.

      MFA and gauges problem

      Right after the fuel pump is mounted and wired, fuel tank filled with 20-25 Liters of fuel I tried to start engine.

      The first I noticed it's a little electrical noise right below the steering every time I turn the key to on.

      Immediately I stopped starting engine and look to the reles and fuses box. Didn't see anything, no smoke, didn't smell anything strange, so I try again to start engine. The noise came again. With my finger I touch a souspicious rele while the key is trying to turning on the engine. I felt how this rele vibrates at the same time of the noise.

      The engine felt like it's gonna turn on, so I try again and again... Engine sounds like better at every try. But in one of them, the crunchy noise stopped and I can see the MFA displays are now erased. I turn off the key and turn on again. Is at that moment when the MFA displays all its lines, making impossible to read anything.

      Hopefully for all I am a documan, so I recorded the noise:

      Which relay is making the noise? The one centered in the video is the hazard/turns relay.

      Yes, that grey one was relay where I felt vibration.

      Around second 20", if you pay attention, you should listen a sound at the same time of acceleration. It's like a kitty meowing:



      I remember years ago reading about vacuum hose problems of the gauge cluster. Maybe now I have it too? And what relation have with the electrical sound of the other video?
