Help with BMW 325

Good to all a few days ago postie that this BMW 325 is 2.7 liter engine I did not want to start and they recommended to take it to scan, I scanned it and the computer does not give me errors in any sensor however it still still does not reach the signal to the fuel pumps, I also have a doubt in the cables that reach the ineters must mark me signal in a cable or in both?

Good, in the injectors a CBLE is common in all the injectors, and you have tried the fuel pump outside the deposit, and if so you have tested the cables from the pump to the engine. I await your answer

Good thanks

if in fact the bomb was the new mountain PQ had been linked, out there the fault because the vehicle was stopped for 1 or 2 months and when trying to start it again, it did not want to start, I changed the pump but now it does not reach a sign, I have not reviewed the lines yet.
Another issue is that if direct current amount to the pumps and I put Ether in the admission the engine starts but when the Ether effect is finished.

Good, then then the pump discarded, if it starts, it is that either gasoline does not arrive because the sleeves are obstructed, the injectors are dirty, or the gasoline pump, it does not work, test has unwind the tubes of the injectors that comes from the pump and start it if they throw gasoline through the tubes is that the pump works from the deposit and the injection pump they work, well if this part goes well, it goes well. Clean them in a gas station or pressure air, but on the side that is involved in the engine not where the injection pump pipes are mounted. You will tell me how it has gone
