After changing the fuel pump an X80 there is a problem with the running of the engines. If both engines are started simultaneously both engines run fine, if we switch off one engine or try to start only one the engine doesn't run or start. Does anybody know the problem? Should the engines be reset with the computer?

If there's a battery shut-off, kill the power and disconnect the batteries for a couple of minutes. Clean the terminals and re-connect them without making repeated contact (put the clamps on in one motion, quickly). See if this changes anything.

Hi Jimn, will try if it works and will keep you up to date.

The problem was solved by switching the connections of the pumps. During the last fuel pump change we had switched the connections!!!
