problems on

Hello to all the colleagues I would like to do and thank the answers a lot, I am repairing a Twigo year 2000 with a direct injection system, the car was towed to the workshop after checking it detects low fuel pressure so it changes the pump, however the car turns on the Detect a connection that bridges the electrical signal of a relay that connects the air conditioning compressor signal and an electro fan with the fuel pump signal (white cable with white wire with yellow) is looking for the fuel pump relay I forgot to disconnect the electrors

The only thing that I recommend, after making those checks and exaustive corrections, is that you look for another computer from another vehicle of the same model and year, and look to see if you have the same problem.
Greetings,

Try feeding the pump directly from the battery, with two cables and you have the test again if everything is fine you have a land problem. There are several solutions for this but check first.

The first thing you should do is disconnect the
relief fans, since they send the circulation to the ground
(in the relay (s)), in which they are connected.
Then, check the fuses, the feeding and ground cable the fuel pump. The engine must work and the fans can make them work with new rereadors or check the original installation and maintain it.
Greetings and Luck Friend. [/B]
