multiple misfire on 2005 Nissan Altima

My 2005 Nissan Altima would not start. Replaced a fuse in the ECM. Worked for two days and the check engine soon light came on. On the third day, it would not start. What could it be now?

a blown fuse will be a short to ground on one of the ECM powered circuits,a thorough inspection of the harness for pinched/chafed wires is in order if this doesn't work put a fresh fuse in and do a wiggle test until you narrow down what section of the harness makes the fuse blow.
