Ok, checked and cleaned. Problem still happening but this was a quick and important check to do. In last picture the ground is incorrect mounted. I fixed after the shot. I have more questions and more pictures to upload in the next post.

Thanks guys, I'll check it later today. I think it's possible the reason, because I put in and out the battery few times, because I use the same for my two cars.

I checked some grounds, but I don't know where is that one you mention 🤔

I had being moving the terminals of the battery and sometimes the cluster gauge displays all numbers, sometimes a few, sometimes none... I don't know if the problem came from the battery wires. I tired holding for 3 seconds the MFA button. Nothing happened. Anyway, I pulled out the gauge cluster to make some checkings, but I don't know how to start.

Ok, I will check grounds. Yes, I think. I will try again. Thanks

Ok, I will try pulling out the cluster. Do you think the new fuel pump wiring can cause this issue? Not only fuel pump was replaced, also the level indicator and I think this was connected correctly, because the fuel level indicator connections doesn't matter its positions:

Also, notice that water temp and oil pressure lights do not work on key turn on position.

Thanks for your response. Any other wiring mods done to the car? Well, it have a bixenon kit since years ago. That's the only. The cluster gauge works fine since I own the car 12 years ago. The bixenon is mounted since then. The displays were fine until I try to start the engine with the new fuel pump, what had a shorten black wire (pictures). This shorten wire I already fixed with an extension cable. I read about Voltage Regulator at PCB of the cluster. But I don't know, I think is not my problem because the fuel level and coolant temperature are working, and the RPM needle moves when you accelerate at least 2500-3000rpm (I know this RPM by engine sound). This needle RPM move is not constant, it's a little jump from 0 to 1000rpm and go down again. Very strange. Maybe you are right and is a missing ground. The car battery was removed months ago because dies. I constantly changing the battery with my daily car to run the Corrado.

Hey guys, how you doing. I'm new here (account from 2008, two posts) and I need help with my cluster gauge. Just at the same time I get the engine running again (fuel pump and fuel leveler replaced) , I lost the displays on my cluster gauge: 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 and have no relation of any kind to this new problem. I said that because I had a problem with one wire of the fuel pump: Because yellow is touching black terminal, I put a plastic clamp between them to fix it. don't think this is the cause of the problem, I think it's only a coincidence. 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: Gauge cluster video: 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? Ok, this was months ago. But, after this worldwide situation, I begin again with that issue in my Corrado. But the problem now is both displays are gone. I have one battery for my two cars, and I put it in my Corrado when I want to start it and drive through the garage. I made this during last month without any troubles, but the other day the displays gone. Do you know if this is another symptom of whatever (different than other things we talk here)? I don't pulled out gauge cluster yet, so this will be the next step if you don't say something different. If my gauge cluster is dead, I will like to swap it to the modern version with de 'Corrado' and the red needles. Do you know if my +91 gauge cluster is 100% compatible with that? Excuse me for posting this here and make a lot of questions, but really need help. After fuel pump replacement, my Corrado it is supposed to be prepared to return to the road again, after 10 years, but I can't do it that way. Thanks and regards.

[b:3akau9rg]Yeah, really nice job that bumper!! :notworthy: You save 200

I know you like my exhaust... :norty:
