2010 tundra will not start

I have a 2010 tundra. It showed a cylinder 2 misfire, so I changed all the spark plugs and the coil for cylinder 2. Now it shows codes that all of the cylinders are misfiring. It will turn over but will not start. I checked that fuel is getting to the engine and I tested all of the other coils with a multi meter. Could it be the ECM? any help would be appreciated.

 

Welcome . Is it a 5.7 or 4.6 ?

 

It is a 4.6

 

You could start by disconnecting the battery for a few minutes.
While you are waiting, check connections. Check wires also.
Rodent damage seems to be common this time of year.

 

I think you would have to troubleshoot the mechanical side first before you replace the ECM... Nothing like investing your kidneys on a problem that is not there.... Possible loose ground, or damaged ground??

 

I hope that you used either Denso or NGK sparkplugs. Did you do the work with the battery connected? If so I agree with fixnfly on the battery disconnect for a few minutes.
