Dear sirs

Hi,I Have a volvo 440gl, from 1989, with a 1.7 Liter engine. Engine code. B18F. The car won`t start. The fuelpump are not priming the engine, in the 3 secunds, as it should. When i turn the kee to start position, the starter is turning. There is also spark on the sparkplugs. The fuelpump is new, and i have also change the fuelpumprelai, and the main relais in the fusebox. When i connecting a wire betwine 30 and 87 on the fuelpumprealiswitch, the fuelpump are pumping normaly. Its like the ECU doesent get any electriciti, because i think that the ECU should give a message to the fuelpump to start. maybe its the ignition switch?. I have tjeckt all the cabels, and i can`t see any leaking. I have also cleant all the earths wires without any result. What can it be???

Thanks and

Many kind reguards Dennis
