no spark on cylinders 1 & 4 df115

[swfl86]

Didn't do it as a test that is what it started doing so i started checking to see why it was losing power.I check the fuel system filters,hoses,injector's,pump everything was working so moved on to electrical component's. Found the coil on cylinder's 1-4 wasn't working so replaced it still no spark switched coil's put the one that was on 2-3 on 1-4 still no spark on 1-4 and that is where i am at now.Thanks for the help.

I find it hard to believe that a four cylinder engine running on two cyls could make to six thousand rpm let alone the vibration. the ecu won't let the engine rev over three in neutral,and That test you done tells me that the coil is being switched, whether the coil saturation time is not long enough I dont know. It would save a lot of time if you could borrow another ecu and try it.
