Open injector circuit.

Hello, I have a problem with Husqvarna, after connecting to ibeat, I get a 2080 error. The fuel pump not priming and there is no spark. I have two ECU: one original from 2008 TE 250 and one from TE 310 2009, on the original ECU the fault was displayed earlier, but on another ECU there was no problem and the pump was priming and there was a spark, but now after I disconnected the tank and replaced tilt sensor resistors ( earlier i have a fault with tilt sensor but after I change the resistors the error no longer shows.) the fault is already on each ECU.
I checked the fuses (ok) , but I only have two fuses connector, in the service manual I saw that there should be three fuses. What should i check to get rid of the problem? Sorry for my bad english :/

Re-check the fuses, with a voltmeter. or replace them them with new fuses.

You must check the entire length of the power wire for the coil and the fuel pump AND the ground wires for the coil and the fuel pump. partially disconnected wires, rubbed bare wires can be make your problem come and go every time you take the tank off and move stuff around.

How can I check that the ECU is good or not fried ?
