could i have a bad ecm? the trouble code i got when it was scanned was p0650 check engine light will not come on when switch is on

checked all fuses and all are good.checked all wires and connectors replaced instrument cluster still no check engine light. noticed that my information button does not work would that affect the check engine light?

i have a 2007 aura xr and the fuse for the ignition (2 amp) powers the check engine light and the menu button on the steering column-i get a P0650 and the menu button won't work when this fuse is blown. Any ideas why? It did not work when I got the car, I found this fuse was bad after investigating this and replaced it-everything worked for at least half a year including the remote starter (that will not work if there is a code like P0650, CEL fault), so it is weird that all of a sudden it is blowing fuses again and not working,,,these cars are electrical nightmares.

I have an 08 and it absolutely won't start right now. I was at work went and got food at lunch and now it won't crank. I'm lost I've been told it's my computer but do they go that fast?
