Fuel phenomen

[ekstroemtj]

Yesterday driving home from my holidays in france. On the way i already feel the car doesnt have that much power. I thought maybe the very high outside temp could be one reason.  Max speed which i got 240. thats a joke for a Turbo S.

When i had the warning on my display to take fuel i know there are many kilometers i can drive on the last liters. But what happend here i never saw before.  The display is showing the remaining km you can drive until your tank is empty.  I noticed that this number went down within some minutes from 90 to 40 km very fast. Even i was driving very careful during this short period. Never could be the car used that much petrol in some few minutes. I paniked almost because highway and no station so far. I take next exit and luckily found a gas station. 

I was thinking what was this. Some problems with the gauge. Some problems with fuel pumps?

Thanks Loren. I read it . 

The fuse trick i did already. Take 13 and 14 out and start. No prob. Looks pumps are ok. Fuses are ok.

where to look for open cicuit / short circiit?

 

merci

Try a new relay.

Any other wiring problems could take some time to trace down.

[ekstroemtj]

Great. Thanks. Do you know if the relay from CS and CTTS are the same? If so injust can try with my cars.

[Loren]

Yes, all the V8 engines use the same relay.

Great. Thankx for helping. Will try tomorrow.
